5.1 RECEPTION

1. After the transceiver has been installed, ensure that the power supply
and antenna are properly connected.
2. Press the POWER SWITCH on.
3. Turn the SQUELCH CONTROL knob fully counterclockwise. This
state is known as "squelch off".
4. Turn up the volume until noise or audio from the speaker is at a
comfortable level.
5. Turn the squelch control knob until the random noise just disappears.
This state is known as the "squelch threshold."
6. To turn on the backlight for the display, press the LAMP key. Each
press of the LAMP key changes the intensity (bright, dim and off) .
7. Rotate the CHANNEL SELECTOR KNOB to select the desired
channel. Refer to the channel chart in the OWNER'S MANUAL
SUPPLEMENT for available channels.
8. When a message is received, adjust the volume to the desired
listening level. The "BUSY" indicator in the LCD is displayed indicating
that the channel is being used.

5.2 TRANSMISSION

1. Perform steps 1 through 7 of RECEPTION.
2. Before transmitting, monitor the channel and ensure it is clear. THIS IS
AN FCC REQUIREMENT!
3. Press the PTT (push-to-talk) switch. The TX indicator on the LCD is displayed.
4. Speak slowly and clearly into the microphone, hold the microphone
about 1/2 inch away from your mouth.
5. When the transmission is finished, release the PTT switch.
6. Refer to the OWNER'S MANUAL SUPPLEMENT for standard
transceiver operating procedures.

5.3 TRANSMIT TIME - OUT TIMER (TOT)

With the PTT switch on the microphone held down, transmit time is limited to
5 minutes. This prevents unintentional transmissions. About 10 seconds
before automatic transmitter shutdown, a warning beep will be heard from
the speaker(s). The transceiver will then 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. Also note that
the PTT switch is ineffective while the microphone is in its grounded hanger.
