No input detected. Verify the input signal.
If an input signal is present, raise the
input level until signal LED lights.

exist standby mode
when inputs signal is
present
The output signal level of the source may
be too low to cross the signal detection
threshold of the amplifier (see amplifier
specs on the Extron website,
www.
extron.com
, for details).
Increase the signal level of the source
until the signal LED lights consistently, or
defeat the standby timer.
