Priority Channel (16/9)
The
16/9
key is used to switch priority channels. When you first turn on
the radio, its default priority channel is Ch. 16. To switch priority
channels, hold down the
16/9
key for a few seconds until the priority
channel switches to the other channel. This is particularly useful when
you want to make a non-DSC call and Ch. 16 is receiving a lot of
transmission traffic. The
16/9
key also allows you to exit various opera-
tion modes, ignore incoming calls and cancel outgoing calls.
With a quick press of the
16/9
key the priority channel immediately is
selected with high (25W) transmission power. Press the
16/9
key again
and it selects the last used channel.
PTT (Push To Talk)
This key is on the microphone. Press and hold it down to send a trans-
mission. There is a 5-minute maximum transmission timer, per FCC
regulations.
