6.3 TRANSMISSION

1. Perform steps 1 through 5 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 “

” 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 press-

ing 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 “

” 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.

For an overview of VHF Marine band operating procedures refer to section 3.

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.
