2. Before transmitting, monitor the channel and make sure it is clear.
3. For communications over short distances, press the H/L key until "
displayed on the LCD. This indicates Low power (approximately 1 watt).
Transmitting on 1 watt prolongs battery life. Low power (1 watt) should
be selected whenever possible.

mitting. The transceiver cannot transmit and receive simultaneously.
6. Press the PTT (Push-To-Talk) switch to transmit. The "TX" indicator is
displayed during transmission.
7. Speak slowly and clearly into the microphone. Hold the microphone about
½ to 1 inch away from your mouth.

9. Refer to the OWNWER'S MANUAL SUPPLEMENT for an overview of
common transceiver operating procedures.
4.4 TRANSMIT TIME - OUT TIMER (TOT)
While the PTT switch is held down, transmission time is limited to 5 minutes.
This prevents prolonged (unintentional) transmissions. About 10 seconds
before automatic transmitter shutdown, a warning beep sounds from the
speaker. The transceiver automatically switches to the receiving mode, even
if the PTT switch is held down. Before transmitting again, the PTT switch
must first be released, then pressed again. This Time-Out Timer (TOT) pre-
vents a continuous transmission that would result from an accidentally stuck
PTT switch.
