2. Panel Test Mode

The transceiver’s transmission output, receiver sensitiv-

ity, and other items are measured and QT, DQT, 2-Tone and

DTMF signalling is decoded in this mode.

2-1. To Enter the Panel Test Mode

Hold down [PF1] and turn the power switch on to enter

this mode. The test frequency channel and test signalling

channel will be displayed.

3. Panel Tuning Mode

The transceiver is adjusted in this mode.

3-1. To Enter the Panel Tuning Mode

Press the [PF3] key in the panel test mode.

The adjustment items, the frequency and signalling, other

than the maximum deviation and sensitivity, return to the val-

ues that were effective for the test frequency channel and

test signalling channel before entering the panel tuning

mode.
