AV System Operation Instructions for JPMC Employee Experience Expo
Overview and Prerequisites
This audiovisual system consists of 26 display monitors distributed across multiple interactive kiosk stations throughout the expo floor. The system is designed for a three-hour open-flow event where attendees can engage with digital content at various stations. Before beginning operations, ensure that all power connections have been tested, HDMI cables are securely connected, and that content sources are ready for display. Facility power should be available at each kiosk location, and backup power sources should be identified in case of electrical issues during the event.
Important Safety Notice: All monitors are mounted using specialized mounting hardware. Do not attempt to adjust, move, or unmount displays during event operations. If a monitor appears unstable or shows signs of mounting failure, immediately contact the on-site technical support team and cordon off the area to prevent guest access.
Pre-Event System Power-Up Procedure
Step 1: Arrive at the venue at least 90 minutes before the scheduled event start time. This allows adequate time for full system initialization, content verification, and troubleshooting any issues that may arise. Walk the entire floor to visually inspect all 26 monitor locations before beginning the power-up sequence.
Step 2: Begin with the kiosk stations located in the central floor area. Working from the entrance toward the back of the room ensures that high-visibility stations are operational first and allows you to identify any systemic issues early in the setup process.
Step 3: At each kiosk station, locate the power button on the monitor. This is typically found on the bottom right edge or rear panel of the display unit. Press and hold the power button for approximately 2 seconds until you see the indicator light illuminate. Most commercial displays will show a red standby light that changes to blue or green when actively displaying content.
Step 4: Wait 10-15 seconds after powering on each monitor to allow the display to fully initialize and detect the connected HDMI input source. During this time, the screen may show a "No Signal" message or display the manufacturer's logo. This is normal behavior during startup.
Step 5: Verify that each monitor automatically detects and displays the content from the connected HDMI source. If a monitor shows "No Signal" after 30 seconds, check that the HDMI cable is firmly seated in both the monitor and the source device. HDMI connections can sometimes appear secure but lack proper contact—disconnect and reconnect with firm pressure until you hear or feel a click.
Step 6: If reconnecting the HDMI cable does not resolve the issue, use the monitor's input selection function. Press the "Input" or "Source" button on the monitor (usually located near the power button). Use the navigation buttons to cycle through available inputs until HDMI is selected. Some monitors may have multiple HDMI ports labeled HDMI1, HDMI2, etc.—ensure you select the port matching your physical connection.
Step 7: Repeat Steps 3 through 6 for all 26 monitors throughout the expo space, including those at the Food & Beverage Anchor area near the popcorn and snow cone stations. Document any monitors that fail to power on or display content properly, noting their specific location and kiosk number for troubleshooting.
Step 8: Once all displays are powered and showing content, perform a complete walkthrough of the space from multiple entry points (escalators and primary door entrance). Verify that content is visible and appropriate from typical guest viewing angles and distances. Check for any screens showing distorted images, incorrect aspect ratios, or misaligned content.
Volume and Audio Adjustment
Step 9: Determine which kiosks include audio components as part of their interactive experience. Not all 26 monitors will necessarily have audio output, but any that do require proper volume calibration before guests arrive.
Step 10: For monitors with audio capability, locate the volume control buttons on the monitor itself, typically marked with "+" and "-" symbols or up/down arrows. These are usually positioned near the power button or along the bottom edge of the display.
Step 11: Set initial volume levels to approximately 40-50% of maximum capacity. In an open expo environment with multiple audio sources and ambient noise from the popcorn and snow cone stations, volume must be loud enough to be heard by guests immediately at the kiosk without creating disruptive noise pollution for other areas.
Step 12: Test audio levels by standing at the typical guest interaction distance (approximately 2-3 feet from the display). The audio should be clearly audible without requiring the guest to lean in closer. Then walk to adjacent kiosk stations to ensure audio from one station does not interfere with the experience at neighboring stations.
Step 13: If audio sources include external speakers rather than monitor-integrated speakers, locate the volume controls on the speaker units or amplification equipment. These may be rotary knobs or digital controls depending on the equipment provided. Follow the same volume testing procedure described in Steps 11-12.
Step 14: Make note of the volume settings for each audio-enabled station. During the three-hour event, ambient noise levels may change as guest traffic increases or decreases, potentially requiring volume adjustments. Having baseline settings documented allows you to quickly return to optimal levels if adjustments are needed.
Input Source Management and Content Switching
Step 15: Each of the 26 monitors displays content from a dedicated HDMI source device (such as a media player, computer, or content management system). Under normal operations, no input switching should be necessary as each display is configured to show specific content throughout the event duration.
Step 16: If technical staff determines that content needs to be changed or updated on a specific display during the event, first locate the source device connected to that monitor's HDMI cable. This may be positioned behind the kiosk structure, in an equipment rack, or concealed within the display mounting system.
Step 17: To change content on the source device, access the device according to its specific operating instructions. This may involve using a wireless keyboard and mouse for computer sources, a remote control for media players, or a content management interface for networked systems. Ensure you have the appropriate access credentials before attempting content changes.
Step 18: If you need to temporarily disconnect a source to troubleshoot or replace equipment, first power off the monitor using the power button described in Step 3. This prevents potential damage from hot-swapping HDMI connections and avoids displaying error messages to guests.
Step 19: After connecting a replacement or updated source device, power the monitor back on following the procedure in Steps 3-6. Verify that the new content displays correctly and that any associated audio functions properly before reopening that station to guest access.
Special Features and Considerations
Step 20: The kiosk layout is specifically designed with clear sightlines and balanced grid positioning to prevent congestion during the three-hour event window. Monitor this flow throughout the event. If particular stations become congestion points, technical staff may need to adjust content timing or add directional signage to encourage more even distribution of guests.
Step 21: The Food & Beverage Anchor stations (popcorn and snow cone areas) serve as initial engagement points. If these areas include displays, ensure their content remains operational as these screens create first impressions and help draw attendees deeper into the expo space. Prioritize any troubleshooting needed at these high-traffic anchor locations.
Step 22: Two main entry points exist via escalators and the primary door. Displays visible from these entry points require special attention as they set expectations for the entire event experience. Confirm these displays remain operational and that content is appropriate for first-time viewers who may not yet understand the expo's purpose or flow.
Step 23: The system design allows attendees to approach kiosks from any side. Verify that display angles and brightness levels provide acceptable viewing from all approach vectors. If certain viewing angles show excessive glare or poor visibility, note these locations for potential adjustment in future iterations of this event layout.
Step 24: Throughout the three-hour event, conduct regular system checks approximately every 30 minutes. This involves a quick walkthrough to confirm all 26 displays remain powered and showing appropriate content. Early detection of failures prevents extended downtime that could negatively impact the attendee experience.
Step 25: Monitor the temperature of displays, particularly in areas with limited ventilation or where equipment may be enclosed within kiosk structures. Commercial displays include thermal protection that will automatically shut down the unit if overheating occurs. If a display unexpectedly powers off, allow it to cool for 10-15 minutes before attempting to power it back on.
Step 26: Some displays may include interactive touchscreen capabilities depending on the specific kiosks deployed. If touchscreens are present, verify touch responsiveness during your pre-event checks by testing all areas of the screen surface. Dead zones or unresponsive areas should be reported immediately as they significantly degrade the interactive experience.
Step 27: For interactive displays, periodically wipe screens with provided microfiber cloths to remove fingerprints and smudges that accumulate during guest interaction. This maintains visibility and professionalism throughout the event. Never use liquid cleaners or abrasive materials directly on powered displays.
Event Conclusion and System Shutdown
Step 28: When the three-hour event concludes and all guests have departed the expo space, begin the systematic shutdown process. Start with kiosks furthest from the exit areas and work toward the main entrances. This ensures that any guests still departing see operational displays until they exit.
Step 29: At each kiosk station, first close or exit any interactive content or applications running on the source devices. This ensures data is properly saved and prevents corruption of content files. Follow the specific shutdown procedures for each source device type.
Step 30: After properly shutting down source devices, press and hold the power button on each monitor for approximately 2 seconds until the display shuts off and the indicator light shows red standby mode or extinguishes completely.
Step 31: Leave all HDMI cables connected unless specifically instructed otherwise by the technical installation team. The mounting hardware and cabling are designed to remain in place for the duration of the event setup, and premature disconnection can complicate subsequent event days if this is a multi-day expo.
Step 32: Document any equipment failures, performance issues, or operational challenges encountered during the event. This information is critical for the technical team to address before subsequent events and helps refine the system design for optimal reliability.
Step 33: Secure the area and ensure all power strips or electrical connections are safely positioned to prevent tripping hazards during breakdown activities by other event staff. Coordinate with facility management regarding when full equipment removal and breakdown will occur.
Troubleshooting Common Issues
Problem: Monitor powers on but displays "No Signal" message continuously
First verify the HDMI cable is securely connected at both ends. If the connection is secure, check that the source device is powered on and actively outputting content. Test the HDMI cable by temporarily swapping it with a cable from a working monitor—if the problem follows the cable, it is defective and requires replacement. If the problem remains with the monitor, the HDMI port may be faulty, and the monitor should be replaced if a spare is available.
Problem: Display shows content but with incorrect colors or distortion
This typically indicates an HDMI cable that is damaged or experiencing interference. Replace the HDMI cable with a spare from your toolkit. If the problem persists with a new cable, the issue lies with either the source device output or the monitor input processing. Try connecting the suspect source device to a different monitor—if distortion follows the source, that device requires troubleshooting or replacement. If distortion only occurs with one specific monitor, that display may have internal processing issues and should be powered off and reported for repair.
Problem: Audio is not playing or is extremely quiet despite volume adjustments
Check whether audio is muted on the monitor—many displays have a separate mute function accessed through the on-screen display menu or a dedicated mute button. Verify the source device audio output is not muted and volume is set appropriately within the content application. If using external speakers, confirm they are powered on and their input is set to the correct source. Check all audio cable connections if external speakers are used. If integrated monitor speakers are used and audio still fails, the monitor may have defective speakers requiring replacement.
Problem: Touchscreen not responding to touch input
First clean the screen surface thoroughly with a microfiber cloth—oils, moisture, or debris can interfere with capacitive touch sensing. If cleaning does not resolve the issue, restart the source device as touch driver software may have encountered an error. Verify in the source device settings that touch input is enabled and the correct touch device is selected. If touch remains non-functional, the touchscreen controller may have failed, requiring monitor replacement or technical repair.
Problem: Monitor intermittently powers off and back on
This behavior usually indicates an overheating condition, unstable power supply, or internal electronic failure. Check that ventilation around the monitor is not blocked and that ambient temperature is within the display's operating range (typically 32-104°F or 0-40°C). Verify the power connection is secure and the outlet is providing stable power by testing with another device. If the problem continues, the monitor has a hardware fault and should be replaced to prevent complete failure during the event.
Problem: Content appears stretched or cropped incorrectly
The source device resolution does not match the monitor's native resolution, or the display is set to an incorrect aspect ratio mode. Access the monitor's on-screen display menu (usually via a "Menu" button) and navigate to picture settings. Look for aspect ratio, zoom, or screen fit options and select "16:9," "Full," or "1:1 Pixel" depending on available options. If this does not correct the issue, adjust the output resolution on the source device to match the monitor's native resolution (commonly 1920x1080 for HD displays or 3840x2160 for 4K displays).
Emergency Procedures
In the event of smoke, unusual odors, or visible sparks from any display or associated equipment, immediately power off the affected unit and disconnect it from power if safe to do so. Cordon off the area to prevent guest access and notify facility management and event safety personnel immediately. Do not attempt to use or troubleshoot equipment showing signs of electrical failure or fire hazard.
If a monitor mounting system shows signs of instability or if a display appears to be at risk of falling, immediately evacuate guests from the affected area and establish a safety perimeter. Contact the on-site installation management team who oversees the mounting hardware—never attempt to adjust or stabilize mounted equipment yourself as this requires specialized tools and expertise.
Should a complete power outage occur affecting multiple or all displays, do not attempt to power equipment back on until facility management confirms stable electrical service has been restored. Once power is restored, follow the standard power-up procedure starting from Step 2, understanding that all 26 monitors will need to be reinitialized simultaneously, which may require coordination among multiple technical staff members.
Post-Event Documentation
After event conclusion and system shutdown, compile a comprehensive report documenting system performance. Note which monitors operated flawlessly, which required troubleshooting, and which failed completely. Record any content issues, audio problems, or interactive functionality concerns. Document guest feedback if available, particularly regarding display visibility, audio clarity, and overall technical experience quality. This information enables continuous improvement for future iterations of the expo and helps justify equipment upgrades or modifications where persistent problems are identified.
