Panel Test Mode
This mode is used for making transceiver connection
tests and clearing the memory.
To set Panel test mode, turn on the power with [Side 2]
and [PTT] are still held down and then first release [PTT].
This mode cannot be set when disabled with the FPU.
In Panel test mode, when channel or signalling is se-
lected, the signalling that was most recently used is dis-
played.
Channel
Key operations in Panel test mode are as follows.
[Selector switch] : Use to select the test channel.
[PTT] : For transmit.
[Top 1] : For down signalling.
[Top 2] : For up signalling.
[Side 1] : For setting Panel tuning mode.
[Side 2] : For switching power between Hi/Low.
Enter the LCD all lamp mode if held
down for 2 seconds.
[Orange] : For monitoring.
[Toggle] : For switching between Wide/Narrow.
