3.For communications over short distances, press the H/L key until “ ” is displayed on the LCD. This indicates Low power (approximately 1 watt).

NOTE

Transmitting on 1 watt prolongs battery life. Low power (1 watt) should be selected whenever possible.

4.If using Low power is not effective, select Medium power (2.5 watts) or High power (5 watts) by pressing the H/L key until “ ” (Medium power) or “ ” (High power) is displayed.

5.When receiving a signal, wait until the incoming signal stops before trans- 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.

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.
