ICOM IC M402 VHF Marine Transceiver INSTRUCTION MANUAL

INSTRUCTION MANUAL

VHF MARINE TRANSCEIVER

iM402

This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

i

NOTE FOR RF SAFETY

C AU TIO N

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 6 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 6 meters of the antenna, nor operated at all if any person is touching the antenna. If the antenna cannot be installed at 6 meters or graterI, we recommend touse the one watt setting to minimize RF exposure.

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.

IMPORTANT

READ ALL INSTRUCTIONS

carefully and completely before using the transceiver.

SAVE THIS INSTRUCTION MANUAL —

This instruction manual contains important operating instructions for the IC-M402.

IN CASE OF EMERGENCY

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

Or, transmit your distress call using digital selective calling on

Channel 70.

USING CHANNEL 16

DISTRESS CALL PROCEDURE

1. “MAYDAY MAYDAY MAYDAY.”

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

3. Your call sign or other indication of the vessel

(AND 9-digit DSC ID if you have one).

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

5. The kind of the distress and assistance required.

6. Any other information which might facilitate the rescue.

USING DIGITAL SELECTIVE CALLING

(Ch 70)

DISTRESS CALL PROCEDURE

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

2. Wait for an acknowledgment from a coast station.

• Channel 16 is automatically selected.

3. Push and hold [PTT], then transmit the appropriate information as at left.

TEMPLATE

CAUTIONS

R

WARNING! NEVER

connect the transceiver to an AC outlet. This may pose a fire hazard or result in an electric shock.

CAUTION:

Changes or modifications to this device, not expressly approved by Icom Inc., could void your authority to operate this device under FCC regulations.

NEVER

connect the transceiver to a power source of more than 16 V DC or use reverse polarity. This will ruin the transceiver.

NEVER

cut the DC power cable between the DC plug and fuse holder. If an incorrect connection is made after cutting, the transceiver may be damaged.

NEVER

place the transceiver where normal operation of the vehicle may be hindered or where it could cause bodily injury.

KEEP

the transceiver at least 3.3 ft (1 m) away from the ship’s navigation compass.

DO NOT

use or place the transceiver in areas with temperatures below –4°F (–20°C) or above +140°F (+60°C) or, in areas subject to direct sunlight, such as the dashboard.

AVOID

the use of chemical agents such as benzine or alcohol when cleaning, as they may damage the transceiver surfaces.

BE CAREFUL!

The transceiver rear panel will become hot when operating continuously for long periods.

Place the transceiver in a secure place to avoid inadvertent use by children.

BE CAREFUL!

The transceiver and optional HM-127 employ waterproof construction, which corresponds to JIS waterproof specification, grade 7 (1 m/30 min.). However, once the transceiver or microphone has been dropped, waterproofing cannot be guaranteed due to the fact that the case may be cracked, or the waterproof seal damaged, etc.

OPERATING RULES

◊

PRIORITIES

• Read all rules and regulations pertaining to priorities and keep an up-to-date copy handy. Safety and distress calls take priority over all others.

• You must monitor channel 16 when you are not operating on another channel.

• False or fraudulent distress signals are prohibited and punishable by law.

◊

PRIVACY

• Information overheard but not intended for you cannot lawfully be used in any way.

• Indecent or profane language is prohibited.

◊

RADIO LICENSES

(1) SHIP STATION LICENSE

You must have a current radio station license before using the transceiver. It is unlawful to operate a ship station which is not licensed.

Inquire through your dealer or the appropriate government agency for a Ship-Radiotelephone license application. This government-issued license states the call sign which is your craft’s identification for radio purposes.

(2) OPERATOR’S LICENSE

A Restricted Radiotelephone Operator Permit is the license most often held by small vessel radio operators when a radio is not required for safety purposes.

The Restricted Radiotelephone Operator Permit must be posted or kept with the operator. Only a licensed radio operator may operate a transceiver.

However, non-licensed individuals may talk over a transceiver if a licensed operator starts, supervises, ends the call and makes the necessary log entries.

Keep a copy of the current government rules and regulations handy.

Radio license for boaters (U.S.A. only)

The Telecommunications Act of 1996 permits recreational boaters to have and use a VHF marine radio, EPIRB, and marine radar without having an FCC ship station license.

Boaters travelling on international voyages, having an HF single sideband radiotelephone or marine satellite terminal, or required to carry a marine radio under any other regulation must still carry an FCC ship station license. For further information, see the FCC Ship Radio Stations Fact Sheet.

SCAN OPERATIONS

■

Scan types

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

When the weather alert function is in use, the selected weather channel is checked while scanning. (p. 20)

PRIORITY SCAN

CH 01 CH 02

Set the tag channels (scanned channel) before scanning.

Clear the tag channels which inconveniently stop scanning, such as digital communication use.

Choose priority or normal scan in set mode. (p. 20)

NORMAL SCAN

CH 01 CH 02

CH 06 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.

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.

Warning sticker attachment

A WARNING STICKER is supplied with the transceiver.

To comply with FCC regulations, this sticker must be affixed in such a location as to be readily seen from the operating controls of the radio. Make sure the chosen location is clean and dry before applying the sticker.

■

Antenna

A key element in the performance of any communication system is an antenna. Ask your dealer about antennas and the best places to mount them.

■

Fuse replacement

One fuse is installed in the supplied DC power cable. If a fuse blows or the transceiver stops functioning, track down the source of the problem, if possible, and replace the damaged fuse with a new, rated one.

■

Cleaning

If the transceiver becomes dusty or dirty, wipe it clean with a soft, dry cloth.

AVOID the use of solvents such as benzene or alcohol, as they may damage transceiver surfaces.
