Transmitting while in scan mode
If PTT is pressed while the radio is in scan mode, your dealer or
communications coordinator may have programmed one of the
following options for the transmit channel:
1. When PTT is pressed, the radio will generate an error beep
because your dealer or communications coordinator has
programmed the radio to not allow transmission while the
radio is in scan mode.
2. When PTT is pressed, the radio will switch to and transmit
on the priority channel regardless of the current receive
state. This mode may be referred to as priority only transmit.
3. If the radio has stopped on a channel, or the resume timer is
active, the radio will transmit on the channel it is stopped on
when you press PTT. If you press PTT, while the radio is
scanning channels, the radio will switch to and transmit on
the priority channel (or the first channel in the scan list if no
priority channel is programmed). This mode may be referred
to as (priority) talkback transmit.
4. When PTT is pressed, the radio will transmit on the channel
indicated by the channel selector knob. This mode may be
referred to as channel select transmit.
