8 BASIC OPERATION
8.1 RECEPTION
1. After the transceiver has been installed, ensure that the power supply
and antenna are properly connected.
2. Press and hold the
PWR/VOL
knob until the radio turns on.
3. Rotate the
SQL
knob fully counterclockwise. This state is known as
“squelch off”.
4. Turn up the
PWR/VOL
knob until noise or audio from the speaker is at a
comfortable level.
5. Rotate the
SQL
knob clockwise until the random noise disappears. This
state is known as the “squelch threshold.”
6. Rotate the
CH
knob to select the desired channel. Refer to the channel
chart on Page 136 for available channels.
7. When a message is received, adjust the volume to the desired listening
level. The “
” indicator on the display indicates that communica-
tions are being received.
8.2 TRANSMISSION
1. Perform steps 1 through 6 of RECEPTION.
2. Before transmitting, monitor the channel to ensure it is clear.
THIS IS AN FCC REQUIREMENT!
3. Press the
PTT
(push-to-talk) switch. The “
T X
” indicator on the LCD is
displayed.
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. Position the oval slot labeled
“
MIC
” within 1/2” (1.5 cm) from the mouth for optimum performance.
8.3 TRANSMIT TIME - OUT TIMER (TOT)
When the
PTT
switch on the microphone is held down, transmit time is limit-
ed to 5 minutes. This limits unintentional transmissions due to a stuck micro-
phone. 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.
