MAKING A CALL

Conventional Modes

1. Turn the radio on and select the desired con-
ventional zone and mode (see Selecting a
Zone and Mode).
2. Press and hold the PTT switch on the side of
the radio and speak slowly and clearly into
the microphone area. The red LED lights
continuously when the radio is transmitting.
When you have finished talking, release the

PTT to listen.
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

1. Turn the radio on and select the desired
trunked zone and mode (see Selecting a
Zone and Mode).
2. Press and hold the PTT switch on the side of
the radio and speak slowly and clearly into
the microphone area. The red LED lights
when the radio is transmitting. When you
have finished talking, release the PTT to lis-
ten.
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.
