10.3 TRANSMISSION
1. Perform steps 1 through 6 of RECEPTION.
2. Before transmitting, monitor the channel to ensure it is clear.
THIS IS AN FCC REQUIREMENT!
3. Press the PTT (push-to-talk) switch. The “ ” indicator on the LCD is
displayed.
4. Speak slowly and clearly into the microphone.
5. When the transmission is finished, release the PTT switch.
NOTE
This is a noise-canceling microphone. Position the Oval Slot label “MIC”
within 1 inch (2.5 cm) from the mouth for optimum performance.
10.4 TRANSMIT TIME - OUT TIMER (TOT)
When the PTT switch on the microphone is held down, transmit time is limited to
5 minutes. This limits unintentional transmissions due to a stuck microphone.
About 10 seconds before automatic transmitter shutdown, a warning beep will be
heard from the speaker(s). The transceiver will 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.
10.5 SIMPLEX/DUPLEX CHANNEL USE
Refer to the VHF MARINE CHANNEL CHART (page 91) for instructions on
use of simplex and duplex channels.
NOTE
All channels are factory-programmed in accordance with FCC (USA),
Industry Canada (Canada), and International regulations. Mode of op-
eration cannot be altered from simplex to duplex or vice-versa.
10.6 USA, CANADA, AND INTERNATIONAL MODE
1. To change the modes, hold the [16/9] key and press the [WX] key. The
mode changes from USA to International to Canadian with each press of
the [WX] key.

played for International mode, and “CAN” will be displayed for Canadian

nels in each mode.
