Power On Off
Ensure the power supply is plugged in at the wall socket and the
wall socket is turned on. Using the on/off Volume control knob on
the rear of the desk unit, turn on the unit.
Noise Cancellation
The desk unit is pre-set for optimum noise reduction and adjustment
is not normally necessary. The noise cancellation switch on the rear
of the unit can be used to momentarily disable the noise cancellation
system, hold the switch up in the off position and all noise will be
heard from the remote speaker. Release the switch and the noise
will be removed. Adjust the volume control for a comfortable listening
level.
