Panel Test Mode
The transceiver's transmission output, receive sensitiv-
ity, and other items are measured and QT, DQT, 2tone and
DTMF signaling is decoded in this mode.
• 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.

Panel Tune Mode
The transceiver is adjusted in this mode.
• To enter the panel tune mode
Press the [GR ] key in the panel test mode.
In this mode, QT and DQT signalling is decoded, but
2tone and DTMF signalling is not decoded.
The adjustment items, the frequency and signalling,
other than the maximum deviation and sensitivity, return to
the values that were effective for the test frequency chan-
nel and test signalling channel before entering the panel
tune mode.
