Avoiding image retention
Image retention can occur when static content appears on the display panel in as little as a few hours.
Image retention is not covered under warranty. To prolong the life of your display panel, follow these
recommendations.
• Operate the display panel within its rated ambient environment. Christie recommends an
operating temperature of 0 to 40 degrees Celsius (32 to 104 degrees Fahrenheit), with a
maximum relative humidity of 90%.
• Avoid static content. Christie recommends displaying moving images whenever possible, and
using a screen saver with a moving image.
• Turn off the display panel when it is not in use, or use the Scheduling feature to automatically
turn off the display panel at preset times of the day.
• Turn on the Pixel shift setting.
• When designing content for the display panels, consider the following:
• Regularly change the color of the text and background of the content
• Move text or images around the display
• Use colors of similar brightness levels
• Avoid using text color and background color with contrasting brightness, for example black
and white.
• Gray may contribute to image retention
Index of parts and modules
Check module markings, parts lists, and the relevant replacement procedure to ensure the module is
replaced correctly.
Components must be replaced with exact equivalents. Failure to do so may result in unsafe operation.

Troubleshooting
Learn about common issues and their solutions.
Understanding the LED status indicators
Identify the LED state flashing pattern and meaning.
LED Status Status of the monitor
Power LED not lit Power on
Power LED lit Power off (Standby mode)
Power LED flashing (slow) Scheduler active
Power LED flashing (fast) Power up/down and software update
Wireless network not available
The wireless network does not appear in the list of available networks.
Resolution
• Ensure the display panel wireless connection is allowed through the network firewall.
• Try searching for wireless networks again.
• If the wireless network does not function properly, use the wired network.
• If the display panel does not function using the wired connection, check the modem and router.
• If the router does not have a problem, check the internet connection of your modem.
Connection is slow
The network connection to the display panel is slow.
Resolution
To get information on the internet service area, connection speed, signal quality, and other settings,
refer to the wireless modem documentation.

Disruption during playback or slow reactions
While content is playing on the display panel, the video is disrupted or slow to play.
Resolution
• Ensure the display panels are at least three meters away from microwave ovens, mobile
telephones, Bluetooth-enabled devices, or any other Wi-Fi compatible devices.
• Change the active channel on the WLAN router.
Internet connection not available
The display panel cannot connect to the internet.
Resolution
• Ensure the display panel wireless connection is allowed through the network firewall.
• The MAC address of the display panel is authenticated each time when connecting to the
internet. If the MAC address of the computer or modem is permanently registered, it is
possible that the display panel might not connect to the internet. Because the display panel
has its own MAC address, the internet service provider cannot validate the MAC address of the
display panel. For this reason, the display panel cannot connect to the internet.
Contact the internet service provider and request information on how to connect a different
device, such as the display panel, to the internet.
Audio video sharing not working
Audio and video cannot be shared to the display panel.
Resolution
• Ensure the display panel wireless connection is allowed through the network firewall.
• The MAC address of the display panel is authenticated each time when connecting to the
internet. If the MAC address of the computer or modem is permanently registered, it is
possible that the display panel might not connect to the internet. Because the display panel
has its own MAC address, the internet service provider cannot validate the MAC address of the
display panel. For this reason, the display panel cannot connect to the internet.
Contact the internet service provider and request information on how to connect a different
device, such as the display panel, to the internet.

Invalid domain
An invalid domain error is displayed when trying to share media.
Resolution
Prior to sharing any files in the media server program on the computer, ensure that an authorized
username and password is used for logging in, and that the domain is active. If the domain is invalid,
this might cause problems while browsing files in Audio Video Sharing mode.
Remote control does not work
Using the remote control has no impact on the display panel.
Resolution
For remote control commands to be received by the display panel, the IR extender cable must be
installed.
In certain conditions, direct light may impact the ability for the IR receiver to identify commands from
the remote control.
