When operating on a channel programmed for digital mode, all
transmissions will be digital transmissions and the radio will receive clear and
digital signals. The PVT light turns on when the private mode is enabled. If
the selected channel is programmed for autoselect capability, the mode may
be toggled between digital and clear with the flex keys (A1, A2). Radios
programmed for forced operation do not allow a change of the transmit mode;
therefore, the flex keys would have no effect.
TRANSFERRING KEYS INTO THE RADIO
