Conventional Modes
Note: Do not interrupt another user. If the present
mode is programmed to receive PL, ensure that
the mode is not in use by pressing the monitor
button to listen for activity.
• If the mode-busy feature is enabled, a blink-
ing red LED on receive (PTT released) indicates
that the mode is currently busy.
• If a mode is programmed for receive only,
any attempt to transmit on that mode will cause
an invalid-mode tone to sound until the PTT
switch is released.
Trunked Modes
Note: If you hear a busy signal (a low-frequency
“bah-bah-bah-bah”), release the PTT switch and
wait for a call-back tone (sounds like “di-di-dit”).
When you hear the call-back tone you will have
three seconds to press the PTT switch. This
allows you to make another call without getting a
busy signal.
1. Turn the radio on and select the desired
zone and mode (see Selecting a Zone and
Mode).
2. Your radio is now set to receive calls on the
selected mode.
