1. After the transceiver has been installed, ensure that the power supply and
antenna are properly connected.
2. Turn the VOL knob clockwise to turn on the radio.
3. Turn the SQL knob fully counterclockwise. This state is known as “squelch off”.
4. Turn up the VOL knob until noise or audio from the speaker is at a comfort-
able level.
5. Turn the SQL knob clockwise until the random noise disappears. This state
is known as the “Squelch Threshold”.
6. Press the [ S

T
] key to select the desired channel. Refer to the chan-
nel chart on page 48 for available channels.
7. When a message is received, adjust the VOL knob to the desired listening
level. The “ ” indicator in the LCD is displayed indicating that the

played.
4. Speak slowly and clearly into the microphone.
5. When the transmission is finished, release the
PTT switch.
NOTE
This is a noise-canceling microphone. The oval slot on the bottom of
microphone should be positioned within 1/2 inch (1.3 cm) from the mouth
for optimum performance.
10.3 TRANSMIT TIME - OUT TIMER
(
TOT
)
When the PTT switch on the microphone is held down, transmit time is limited to
5 minutes. This limits unintentional transmissions due to a stuck microphone.
About 10 seconds before automatic transmitter shutdown, a warning beep will be
heard from the speaker(s). The transceiver will automatically go to receive mode,
even if the
PTT switch is continually held down. Before transmitting again, the
PTT switch must first be released and then pressed again.
