To record, press and hold the Record/Pause button on the Front Panel until you
see the countdown begin on the Front Display. Then, release the button and begin
recording your message by speaking clearly into the internal mic under the top
perforated grill of the unit, or into a hand held mic plugged in to the MIC jack on
the rear of the unit, or by starting an external source plugged into the LINE INPUT
jack on the rear of the unit.
The front panel digital display will count down the total record time available, but
you can pause recording at any time by pushing the record button again. Then, fin-
ish the record process by pushing the play button or continue recording by pushing
the record/pause button again.

Next, determine an open
frequency in your area and
set this frequency on the front
panel display using the up/
down arrow keys. Please see
the “Frequency Selection” page
in this manual to select the
best frequency.
7
To begin playback, press and
hold the Play button until you
see the frequency reappear.
The message will now be
broadcast in a continuous loop.

Finally, monitor the radio signal on
a good car radio to check coverage
and audio quality.
You can try different transmitter
locations and frequency selection
to improve coverage and
minimize noise.
Use of the outdoor antenna/ range
extender will substantially increase
coverage.
