3.2.2.3 Local Mode
Description
Local mode using the built-in front panel control unit of the radio allows the
maintenance staff to operate the radio locally with the highest priority.
In order to change to local control, the LOC key on the radio keypad must
be pressed. If local mode is entered, all possible existing fixed sessions of
remote RC clients change back to monitoring session. In case of local mode
disabled (configurable via service PC), the LOC key does not work.
Local mode cannot be interrupted by remote control. After leaving local
mode, all parameter settings remain valid.
