8. Troubleshooting & Maintenance

1) When there is a color losing or no video signal output, maybe the cables have

already broken or haven’t been connected well.

2) When EDID management does not work normally, probably the HDMI cable is
broken at the output end.

3) When switching, there is a blank screen on the displayer, maybe the displayer does
not support the resolution of the video source. Switch again or manage the EDID
data manually to make the resolution of the video source automatically compliant
with the output resolution.

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 and the communication protocol is correct.

5) When switching , there is no output image:

 Check if there is any signal at the input.
 Check if there is any signal at the output.

If there is no signal input/output, maybe the input/output cables broken or the
connectors loosen, please change for another cable.

 Check if the output port number is the same with the controlled one.
 If it is still the same after the above checking, maybe there is something wrong in

the switcher. Please send it to the dealer for repairing.

6) If the static becomes stronger when connecting the video/audio connectors, it
probably due to bad grounding, please check the grounding and make sure it
connected well; otherwise it would damage the switcher.

7) If the switcher cannot be controlled through the RS232 port, front panel buttons or by
the IR remote, the unit may have already been broken. Please send it to the dealer
for repairing.

9. Safety Operation Guide

In order to guarantee the reliable operation of the equipments and safety of the staff,
please abide by the following proceeding in installation, using and maintenance:

1) The system must be earthed properly. Do not use two blades plugs and ensure the
alternating power supply ranged from 100v to 240v and from 50Hz to 60Hz.

2) Do not put the switcher in a place of too hot or too cold.

3) As the power generating heat when running, the working environment should be

maintained fine ventilation, in case of damage caused by overheat.

4) Cut off the general power switch in humid weather or left unused for long time.

5) Before following operation, ensure that the alternating current wire is pull out of the

power supply:

 Take off or reship any components of the equipment.
 Take off or rejoin any pin or other link of the equipment.

6) As to non-professional or without permission, please DO NOT try to open the casing
of the equipment, DO NOT repair it on your own, in case of accident or increasing
the damage of the equipment.

7) DO NOT splash any chemistry substance or liquid in the equipment or around.
