RECEIVING A CALL
1 Turn the radio on and select the desired
zone and mode (see Selecting a Zone and
Mode on page 20).
2 Your radio is now set to receive calls on the
selected mode.
MAKING A CALL
Conventional Modes
1 Turn the radio on and select the desired
conventional zone and mode (see Selecting
a Zone and Mode on page 20).
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.
3 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
blinking 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 on page 20).
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
listen.
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 have three seconds to press the PTT
switch. This allows you to make another call
without getting a busy signal.
