8.2 Operation
! Connect a cable leading from the INPUT connector of the 123V machine to
the output of the video source.
! Connect up to three video acceptors to the OUT sockets of the 123V
machine. Use best available coaxial cables for connection.
! Connect an appropriate 12VDC source to the DC socket of the 123V
machine. Observe polarity. The built-in LED will light.
! Operate source and acceptor(s).
! Adjust the GAIN and EQ. (cable equalization) control trimmers on the
123V machine only if necessary. Those trimmers are preset at the factory
for unity gain, so re-adjusting them unnecessarily might upset the signal
transparency.
