11. Troubleshooting & Maintenance
1. When images of terminal unit output with ghost, such as the projector output with ghost, please
check the projector’s setting or try another high quality connection cord.
2. When there is a color losing or no video signal output, please check the input and output end
connection of VGA cable.
3. When the remote controller doesn’t work:
A. Change the batteries
B. Remove the batteries, hold the power button for 10 seconds then reinstall the batteries
4. When user cannot control the switcher by computer through its COM port, please check the
COM port number in the software and make sure the COM port is in good condition.
5. When switching, there are codes back but no output image, please check if there is any signal
at the input end. If there is no signal input, maybe the input connection cord broken or the
connectors are loose.
6. If the POWER indicator doesn’t work or no respond to any operation, please make sure the
power cord connection is well.
7. If the output image is interfered, please make sure the system is grounded well.
8. If the static becomes stronger when connecting the BNC connectors, it maybe due to the
incorrect grounding, please correct it otherwise it would damage the switcher.
9. If the switcher cannot be controlled by the buttons on the front panel, RS232 port or IR remote,
the switcher may have broken.
