If all the LED’s on the front panel are blinking together, then the unit has
detected an over temperature condition and is performing a partial shutdown to
prevent damage to the integrated circuits. This condition is reversible and
when the temperature decreases to acceptable levels the extender begins to
function normally again. If over temperature condition occurs frequently, then
the user must allow better cooling and air flow around the box. The enclosure
has a temperature controlled fan on the left side that draws in fresh air and
exhausts the opposite side, make sure the sides are not blocked.
If for a particular channel the Link, Video, and L.R. LEDs are blinking
together, there has been a failure on the corresponding transmitter module or it
is missing. Contact Support.
