Make sure that all your connections are solid, and check the state of the
LED’s on the front of the unit.
Do not open or try to repair the unit yourself. There is no customer
repairable item in the unit and you will void your warranty. Contact HRT
Support at 714-641-6607 or via email or web. If you need to ship your
switch for repair, make sure to get a Return Material Authorization
(RMA) number first.
Cable Length Limitations
The switcher cannot be used as an extender. Therefore it is best to plug
the output of the switch directly to the display device and use input cables
that are 5 meters (16 ft) maximum. In other words, try to keep the total
length of cables from the video source to the box and from the box to the
monitor should not exceed 16 feet. At longer distances you may
experience video degradation. If you cannot use shorter cables, try to set
the refresh rate and/or resolution of the video signal to a lower level.
