6.3 TRANSMISSION
1. Perform steps 1 through 7 of the RECEPTION discussion above.
2. Before transmitting, monitor the channel and make sure it is clear.
THIS IS AN FCC REQUIREMENT!
3. For communications over short distances on the Marine band, press the
[H/L] key until “L” 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. On the FRS and MURS
bands, the transmit power is fixed (0.5 Watt: FRS band, 2 Watts:
MURS band).
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 “M” (Medium power)
or “H” (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.
7. Speak slowly and clearly into the microphone. Hold the microphone about
1/2 to 1 inch away from your mouth.
8. When the transmission is finished, release the PTT switch.
Refer to section 14 “CHANNEL ASSIGNMENTS” for an overview of VHF
marine, FRS and MURS band operating procedures.
6.3.1 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, and then pressed again. This Time-Out-Timer (TOT)
prevents a continuous transmission that would result from an accidentally
stuck PTT switch.
