BASIC OPERATION

■ Transmitting

Before transmitting, read the call procedures at right.

➀ Select an operating channel. See pgs. 5–6 for details.

➁ Push [H/L] to select a transmit output power.

•“LOW” appears when low output power is selected.

• High power cannot be selected on some channels. Refer to the

channel list on p. 18.

➂ Push and hold the [PTT] switch to transmit.

•“$” appears.

➃ Speak into the microphone at your normal voice level.

• Do not hold the microphone too closely to your mouth or speak to

loudly. This may distort the signal.

➄ Release the [PTT] switch to receive.

☞ IMPORTANT: In order to maximize the readability of

your transmitted signal, pause for a moment after push-

ing [PTT], hold the microphone 15–20 cm from your

mouth, then speak into the microphone at an even, nor-

mal voice level.

MOMENTARY HIGH POWER

On USA channels 13, 15 and 67, transmission using high

power is momentarily possible. To use high power, push

and hold [H/L] while transmitting.

TIME-OUT TIMER (USA version only)

The transceiver has a time-out timer function to prevent

continuous, long transmissions. Transmit is automatically

inhibited after 5 min. of continuous transmission.

CALL PROCEDURES

You must identify yourself when you transmit and you must

respect time limits.

Give your call sign each time you call another vessel or a

coast station. If you have no call sign, identify the station

by giving the vessel name and the name of the license.

2) Give your call sign at the end of each transmission that

lasts more than 3 minutes.

3) You must pause and give your call sign at least once

every 15 minutes during long ship-to-shore calls.

4) Keep your calls short (less than 3 minutes). Wait 2 min-

utes before repeating a call.

5) Unnecessary transmissions are not allowed.
