EXPLICIT DEFINITIONS
WORD
DEFINITION
Personal injury, fire hazard or electric
RWARNING shock may occur.
CAUTION
NOTE
ii
Equipment damage may occur.

CAUTIONS
IN CASE OF EMERGENCY
RWARNING! NEVER connect the transceiver to an
AC outlet. This may pose a fire hazard or result in an electric
shock.
If your vessel requires assistance, contact other vessels and
the Coast Guard by sending a distress call on channel 16.
RWARNING HIGH VOLTAGE! NEVER touch
the antenna or an internal antenna connector during transmission. This may result in an electric shock or a burn.
❍ USING CHANNEL 16
DISTRESS CALL PROCEDURE
NEVER connect the transceiver to a power source of more
than 16 V DC. This connection will ruin the transceiver.
1. “MAYDAY MAYDAY MAYDAY.”
AVOID using or placing the transceiver in direct sunlight or
2. “THIS IS ...........................” (name of vessel)
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.
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.
KEEP
the transceiver and microphone at least 1 meter
away from your vessel’s magnetic navigation compass.

OPERATING RULES
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.
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.
• 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
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.
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.
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.

■ 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.
When dual watch is selected in SET mode:
➥ Push [CH/WX • DUAL] for 1 sec. to start dual watch.
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

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.
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.
• “$” 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.
v 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.
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.
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.
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.

BASIC OPERATION
■ 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.
TAG

Appears when the channel is
specified as a tag channel.
D Scan operation
➀ Select the desired channel group (USA, CAN, INT or WX)
channels with [CH/WX] + [H/L] (or [CH/WX] only for
weather channels).
• When the weather alert function is in use, select the desired WX
channel in the display, then perform the above step.
➁ Push [SCAN] to start scanning.
• “SCAN” appears and flashes in the function display.
• “16” appears during priority scan.
➂ To stop the scan, push [SCAN] again.
• “SCAN” disappears.
✔ Scan resume timer
When a signal is detected, scan pauses until the signal disappears or resumes after pausing 5 sec., according to the
SET mode setting. (p. 12)
✔ Confirming tag channels
While operating scan, push [UP] or [DN].
• Only tag channels are selected.
• Stop pushing [UP] or [DN] to resume scan.
✔ Clearing all tag channels
✔ Weather alert function
While pushing [H/L], push [SCAN • TAG] for 3 sec. until the
long beep becomes 2 short beeps.
When this function is turned ON (p. 12), the selected weather
channel is checked during scan. Refer to p. 6 for a description of weather alert.
• All tag channels in the selected channel group are released.
