IN CASE OF EMERGENCY

If your vessel requires assistance, contact other vessels and the Coast Guard by sending a Distress call on Channel 16.

USING CHANNEL 16

DISTRESS CALL PROCEDURE

1.“MAYDAY MAYDAY MAYDAY.”

2.“THIS IS ...............” (name of vessel).

3.Say your call sign or other indication of the vessel (AND 9-digit DSC ID if you have one).

4.“LOCATED AT ...............” (your position).

5.State the nature of the distress and assistance required.

6.Give any other information which might facilitate the rescue.

Or, transmit your Distress call using digital selective calling on Channel 70.

USING DIGITAL SELECTIVE CALLING (Ch 70)

DISTRESS CALL PROCEDURE

1.While lifting up the key cover, push and hold [DISTRESS] for 5 sec. until you hear 5 short beeps change to one long beep.

2.Wait for an acknowledgment on Channel 70 from a coast station.

•After the acknowledgement is received, Channel 16 is automatically selected.

3.Push and hold [PTT], then transmit the appropriate information as listed above.

INSTALLATION NOTE

The installation of this equipment should be made in such a manner as to respect the EC recommended electromagnetic field exposure limits (1999/519/EC).

The maximum RF power available from this device is 25 watts. The antenna should be installed as high as possible for maximum efficiency and that this installation height should be at least 5 meters above ground (or accessible) level. In the case where an antenna cannot be installed at a reasonable height, then the transmitter should neither be continuously operated for long periods if any person is within 5 meters of the antenna, nor operated at all if any person is touching the antenna.

In all cases any possible risk depends on the transmitter being activated for long periods. (actual recommendation limits are specified as an average of 6 minutes) Normally the transmitter is not active for long periods of time. Some radio licenses will require that a timer circuit automatically cuts the transmitter after 1–2 minutes etc.

Similarly some types of transmitter, SSB, CW, AM, etc. have a lower ‘average’ output power and the perceived risk is even lower.

■ AquaQuake water draining function

The IC-M603 uses a new technology to clear water away from the speaker grill: AquaQuake. AquaQuake helps drain water away from the speaker housing (water that might otherwise muffle the sound coming from the speaker). The ICM603 emits a vibrating noise when this function is being used.

While pushing and holding [H/L], turn power ON.

•A low beep tone sounds while [H/L] key is pushed and held to drain water, regardless of [VOL] control setting.

•The transceiver never accepts a key operation while the AquaQuake function is activated.

While pushing and holding [PTT] on the optional HM-162E, turn power ON to clear water away from the HM-162E.

3 BASIC OPERATION

■ Optional Voice scrambler operation

D Activating the scrambler function

The optional Voice scrambler provides private communications. In order to receive or send scrambled transmissions you must first activate the scrambler function. To activate the function, an optional scrambler unit is necessary. See pgs. 45 and 50 for setting the scrambler unit. Ask your dealer for details.

The scrambler function automatically turns OFF when Channel 16 or 70 is selected.

qRotate [SELECTOR] to select the desired channel other than Channel 16 and 70.

wPush [F], then push [0] to turn the Voice scrambler function ON.

• “SCRAM” appears.

eTo turn the scrambler function OFF, repeat step w.

• “SCRAM” disappears.

D Programming scrambler codes

There are 32 codes (1 to 32) or 128 codes (0 to 127)* available for programming when an optional scrambler unit is installed. In order to understand one another, all transceivers in your group must have the same scramble code. This function may not be available depending on dealer setting.

*Depends on the installed scrambler unit.

qWhile pushing and holding [!6•C], push [POWER] to enter Set mode.

• Turn power OFF in advance.

w After the display appears, release [!6•C].

eRotate [SELECTOR] to select the “Scrambler Code,” push [ENT].

r Rotate [SELECTOR] to select the desired scrambler code. t Push [ENT] to set and exit the scrambler code item.

yPush [CLR], or rotate [SELECTOR] to select “Exit,” then push [ENT] to exit Set mode.

DUALWATCH/TRI-WATCH 4

■ Description

Dualwatch monitors Channel 16 while you are receiving on another channel; Tri-watch monitors Channel 16 and the call channel while receiving another channel. Dualwatch/Triwatch is convenient for monitoring Channel 16 when you are operating on another channel.

DUALWATCH/TRI-WATCH SIMULATION

Call channel

Dualwatch

Tri-watch

•If a signal is received on Channel 16, Dualwatch/Tri-watch pauses on Channel 16 until the signal disappears.

•If a signal is received on the call channel during Tri-watch, Tri-watch becomes Dualwatch until the signal disappears.

•To transmit on the selected channel during Dualwatch/Triwatch, push and hold [PTT].

■ Operation

q Select the desired channel.

wPush [F], then push [1• DUAL ] to start Dualwatch or [2• TRI ] to start Tri-watch.

•“DUAL 16” appears during Dualwatch; “TRI 16” appears during Tri-watch.

•A beep tone sounds when a signal is received on Channel 16. e To cancel Dualwatch or Tri-watch, push [CLR] or repeat

step w.

[Example]: Operating Tri-watch on INT Channel 25

5 SCAN OPERATION

■ Scan types

Scanning is an efficient way to locate signals quickly over a wide frequency range. The transceiver has Priority scan and Normal scan.

PRIORITY SCAN

	CH 01	CH 02
CH 06	CH 16	CH 03
	CH 05	CH 04

Priority scan searches through all TAG channels in sequence while monitoring Channel 16. When a signal is detected on Channel 16, scan pauses until the signal disappears; when a signal is detected on a channel other than Channel 16, scan becomes Dualwatch until the signal disappears.

Set the TAG channels (scanned channel) before scanning. Clear the TAG channels which inconveniently stop scanning, such as those for digital communication use. (Refer to the right page for details.)

Choose Priority or Normal scan in Set mode. (p. 43)

NORMAL SCAN

CH 01	CH 02
CH 06	CH 03
CH 05	CH 04

Normal scan, like priority scan, searches through all TAG channels in sequence. However, unlike priority scan, Channel 16 is not checked unless Channel 16 is set as a TAG channel.
