Transmitting

Conventional Modes
1. Turn the radio on and select the desired mode.
2. Do not interrupt another user. If the mode on which
you are transmitting is programmed to receive PL
(Private Line) or DPL (Digital Private Line),
ensure that the channel is not in use by listening to
activity. If the green LED is solid while receiving
(PTT released), this will indicate that the channel is
currently busy and you should not transmit.
3. When the channel is available, press and hold the
PTT switch and speak slowly and clearly into the
microphone. The red Tx LED will light continuously
while the radio is transmitting. When you have
finished talking (transmitting), release the PTT to
listen (receive).
Note:
• 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 Systems
1. Turn the radio on and select the desired trunked
mode.
2. Press the PTT switch. Speak slowly and clearly into
the microphone area. The red Tx LED will light
while the radio is transmitting. When your
transmission is completed, release the PTT to listen.
Notes:
• If you hear a busy tone (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,
allowing you to make your call without getting
another busy signal.
• If a continuous talk-prohibit tone is heard when
the PTT switch is pressed, it means that the
radio is out of range and you will not be able to
transmit.
