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.
