Remote Control Lights -
When in Programming Mode – The power light comes on and stays on.
Generally you have 10 seconds to enter a command or the
remote will exit Programming Mode.
Programming Success – The remote flashes the power button light two times
Programming Error – The remote fast flashes the power button light for one
second
Remote Out-Of-Range – Alternating flash of power button light and Xtender
Channel lights (Red/Green/Blue) – this occurs if the remote
is too far from the Xtender – either move closer to the
Xtender or purchase a BOCS Repeater to Xtend the range of
your wireless remotes.
