"Setting Up Group Mode" on every radio in your
group. Then, to record the unit ID and everyone’s
nickname in every radio, send a call to "All" from
each radio one time (see "Sending a Direct Call").
Sending a Direct Call

talk to.

in
group mode. The radio flashes ALL. Then, press
d-call
again. Everyone in your group receives a call
"chirp" for about 3 seconds. When the chirp ends,
begin your conversation.

When you make a direct call to "all," your
radio also sends out your nickname or ID so that it
will show up in the call list for everyone in your
group.

other people know, press
d-call
in group mode.
Then, use

the person you called until 15 seconds after your
last conversation. Then, your radio automatically
exits private mode.

channel change for everyone in your group. You
might want to do this when you find you are getting

Your radio chirps for about 10 seconds while it
sends out the channel change signal. As each
radio receives the channel change signal, it chirps
once, then changes to the new channel.
To ensure all radios make it to the new channel, we
recommend you:
•
Make sure you are in an open environment,
where the radio will get the best range.
•
Optimize range during the channel change
signal by raising the radio over your head to give
the best possible height.
•
Do a "roll call" on the new channel after the
move to be sure no one was left behind. If you
missed someone, return to the previous channel
and issue the signal again.
