EXPLICIT DEFINITIONS

WORD

RWARNING

DEFINITION

Personal injury, fire hazard or electric shock may occur.

CAUTION

Equipment damage may occur.

NOTE

If disregarded, inconvenience only. No risk of personal injury, fire or electric shock.

FEATURES

☞

Durable, water-resistant construction

Built tough to withstand the punishing marine environment, the IC-M45A offers reliability you can count on.

☞

Dual watch and tri-watch functions

Convenient functions which allow you to monitor the distress channel (ch 16) while receiving a channel of your choice—dual watch; or monitor the distress channel and another channel while receiving a channel of your choice—tri-watch.

☞

Large, easy-to-read LCD

With dimensions of 20(H)

× 60(W) mm, the IC-M45A’s function display is easy to read and shows operating conditions at a glance. Backlighting and contrast can be adjusted to suit your preferences.

☞

‘Smart’ microphone

Operating channel and transmit output power level settings are easily selectable via the supplied microphone.

☞

Simple operation

Ergonomic design with a minimum number of switches and controls provides simple intuitive operation.

CAUTIONS

RWARNING! NEVER

connect the transceiver to an

AC outlet. This may pose a fire hazard or result in an electric shock.

RWARNING HIGH VOLTAGE! NEVER

touch the antenna or an internal antenna connector during transmission. This may result in an electric shock or a burn.

NEVER

connect the transceiver to a power source of more than 16 V DC. This connection will ruin the transceiver.

AVOID

using or placing the transceiver in direct sunlight or in areas with temperatures below –20°C (–4°F) or above

+60°C (+140°F).

DO NOT

operate the transceiver without running the vessel’s engine. When your vessel’s engine is OFF and the transceiver is transmitting, the vessel’s battery will soon become exhausted.

KEEP

the transceiver out of the reach of children.

KEEP

the antenna cable and DC power cable as far away as possible from electrical pumps, generators and other electronic instruments to prevent instrument malfunctions.

KEEP

the transceiver and microphone at least 1 meter away from your vessel’s magnetic navigation compass.

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. Your call sign or other indication of the vessel.

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

5. The nature of the distress and assistance required.

6. Any other information which might facilitate the rescue.

D 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 calls are prohibited under law.

D Privacy

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

• Indecent or profane language is prohibited.

D Radio licenses

SHIP STATION LICENSE

When your craft is equipped with a VHF FM transceiver, 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. This license includes the call sign which is your craft’s identification for radio purposes.

OPERATING RULES

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 near the transceiver or be 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.

A current copy of the applicable government rules and regulations is only required to be on hand for vessels in which a radio telephone is compulsory. However, even if you are not required to have these on hand it is your responsibility to be thoroughly acquainted with all pertinent rules and regulations.

NOTE: Even though the IC-M45A is capable of operation on VHF marine channels 3, 21, 23, 61, 64, 81, 82 and 83, according to FCC regulations these channels cannot be lawfully used by the general public in USA waters.

Weather alert function: NOAA broadcast stations transmit a weather alert tone before important weather announcements.

• When the weather alert function is turned ON the “ALT” indicator appears on the display.

• When the alert signal is received “ALT” flashes with an alert tone and then weather announcements start.

This function is activated when a weather channel is selected or during any scan. See “SET mode items” on p. 12.

■ Receiving

➀

Rotate [PWR/VOL] to turn power ON.

➁

Rotate [SQUELCH] fully counterclockwise.

➂

Adjust [PWR/VOL] to a suitable listening level.

➃

Rotate [SQUELCH] clockwise until the audio noise disappears.

➄

Select a channel. See pgs. 5–6 for details.

• When a signal is received:

➧ The squelch opens.

➧ Audio is emitted from the speaker.

➧ “BUSY” appears in the function display.

➅

When an interrupting signal is received, rotate [SQUELCH] deeply clockwise.

D Dual/tri-watch functions

These functions allow you to conveniently check the distress channel (ch 16) or, both the distress and leisure call channel

(ch 9; programmable) while receiving another channel. When receiving a signal on one of these channels, the transceiver stops on the channel until the signal disappears.

Depending on your preference, select dual watch or tri-watch in advance in SET mode (p. 12). Dual watch is the default setting.

3 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 pushing [PTT], hold the microphone 15–20 cm from your mouth, then speak into the microphone at an even, normal voice level.

CALL PROCEDURES

You must identify yourself when you transmit and you must respect time limits.

1) 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 minutes before repeating a call.

5) Unnecessary transmissions are not allowed.

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.

■ Scan function

The transceiver has a high speed scan function for standing by on utility signals. The scan speed is 8 channel/sec. (except when the weather alert function is in use).

Two scan types are available: normal scan (scans all tag channels in sequence) and priority scan (checks channel 16 while scanning). These scans can be selected in SET mode

(p. 12).

D Setting tag channels

You can specify channels as tag channels for efficient scanning. Tag channels can be set for each channel group (USA,

CAN, INT) independently.

➥ Select the desired channel, then push [

SCAN

• TAG] for 1 sec. to toggle the tag setting.

USA

TAG

Appears when the channel is specified as a tag channel.

✔ Clearing all tag channels
