Transmitting
Trunked Systems
1. Turn the radio on and select the desired system and mode (see “Selecting a
Trunked System 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 will light while the radio is
transmitting. When you have finished talking (transmitting), release the PTT
to listen (receive).
Notes:
• 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 lets you make your call without getting another busy signal.
• If you hear a continuous talk-prohibit tone when you press the PTT
switch, you will not able to transmit. The radio may be out of range.
• To take full advantage of the radio’s noise-cancelling feature, do not block
the noise-cancelling port when transmitting.
Conventional Modes
1. Turn the radio on and select the desired mode (see “Selecting a Conventional
Mode”).
2. Listen for a transmission and adjust the volume control for a comfortable
listening level.
3. Do not interrupt another user. When the radio is receiving, the Smart PTT
feature causes the red LED to blink indicating that the mode is currently busy
and that you should not transmit.
4. When the mode is clear, press and hold the PTT switch on the side of the
radio, and speak slowly and clearly into the microphone area. The red LED
will light while the radio is transmitting. When you have finished talking
(transmitting), release the PTT to listen (receive).
Notes:
• If a conventional mode is programmed for receive-only operation, any
attempt to transmit on that mode will cause an invalid-mode tone to
sound until the PTT is released.
• To take full advantage of the noise-cancelling feature, do not block the
noise-cancelling port when transmitting.
