11 BASIC OPERATION
11.1 RECEPTION
1. After the
GX1150
has been installed, ensure that the power supply and
antenna are properly connected.
2. Turn the
VOL/PWR
knob clockwise to turn the transceiver on.
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
or
keys to select the desired channel. Refer to the chan-
nel chart on page 70 for available channels.
7. When a message is received, adjust the volume to the desired listening
level. The “
” indicator on the LCD is displayed indicating that the channel
is being used.
11.2 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 “
” indicator in the LCD is
displayed.
4. Speak slowly and clearly into the microphone.
NOTE
This is a noise cancelling microphone. The oval slot on the micro-
phone should be positioned within 1/2 inch (1.3 cm) from the mouth
for optimum performance.
5. When the transmission is finished, release the
PTT
switch.
11.3 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.
NOTE
When a transmission was shut down by the TOT, the
GX1150
can not
transmit afterwards for 10 seconds.
