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.
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.

6.4 NOAA WEATHER CHANNELS

1. To receive a NOAA weather broadcast, press the [WX] key. The transceiver changes to
the weather channel mode. This mode consists of a special preset memory bank
containing the NOAA weather channels.
2. The transceiver will be set to the last used NOAA weather channel. Press the [ ] or
[ ] key to change to other weather channels.
3. To exit from the weather channel mode, press the [WX] key. The transceiver will revert
to the channel you were using prior to switching to the weather channel mode.

6.4.1 NOAA WEATHER ALERT

In the event of extreme weather disturbances such as storms and hurricanes, NOAA
(National Oceanic and Atmospheric Administration) sends a "weather alert" consisting of a
1050 Hz tone, followed by weather reports on the weather channels. The transceiver is
capable of receiving this alert if the following is performed:
1. Program your area's weather channels into the transceiver's scan memory. Follow the
same procedure as for regular channels.
2. Press the [SCAN] key to start the scan.
3. The memorized weather channels are scanned along with the regular memorized
channels. Scanning will not stop on the (continuous) weather broadcast channels
