FEATURES
❍ Built-in DSC meets ITU Class D requirement
An independent receiver continuously watches Ch. 70,
while using another channel. Further, a single antenna
connector allows VHF and Ch. 70 operation, thus simplifying installation. The 10-keypad allows simple and
efficient operation of the DSC emergency functions,
vital for your safety at sea.
❍ Superior receiver performance
The IC-M601 has excellent receive specifications of more
than 75 dB for spurious response, and intermodulation
rejection. With such high level performance, received
calls are remarkably clear and free from noise. The powerful audio output from the front facing speaker further
increases the clarity of received calls.
❍ Optional COMMANDMIC
(2 systems are connectable)
The optional COMMANDMIC provides a 2nd and 3rd
station capability and an intercom function. With slim
dimension and sizable LCD, the COMMANDMIC offers
ease and convenience of operating the radio from
remote locations such as the cockpit or tower up to a
max. 21 m* from the IC-M601.
* Requires use of optional OPC-999 extension cables.
❍ Large LCD with dot matrix characters
The large dot-matrix display is designed for optimum
readability in any lighting condition. With the extra large
font, the channel number is maximized on the display
and other information can be easily read.
❍ Rugged waterproof construction
The IC-M601 including the supplied (HM-137)/optional
(HM-134) microphone has effective waterproofing
equivalent to JIS waterproof grade 7*.
* 1 m/30 min; except cables.

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
vessel may be hindered or where it could cause bodily injury.
KEEP the transceiver at least 1 m away from the ship’s nav-
igation compass.
DO NOT use or place the transceiver in areas with temper-
atures below –20°C or above +60°C or in areas subject to direct sunlight, such as the dashboard.
AVOID the use of chemical agents such as benzine or al-
cohol 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, HM-137 and optional
HM-134 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.

DD
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.

normal scan.
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 right
page for details.)
Choose priority or normal scan in set mode. (p. 38)
NORMAL SCAN
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.
PRIORITY SCAN
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.

■ Setting tag channels
For more efficient scanning, add desired channels as tag
channels or clear tag channels for unwanted channels. Channels set as non-tag channels will be skipped during scanning.
Tag channels can be assigned to each channel group (U.S.A.
and International) independently.
q While pushing [H/L], push [DIAL] once or twice to select
the desired channel group, if desired. (depends on version)
w Select the desired channel to set as a tag channel.
e Push [F], then push [5
TAG ] to set the displayed channel
as a tag channel.
•“TAG” appears in the display.
r To cancel the tag channel setting, repeat step e.
•“TAG” disappears.
• Clearing all tag channels in the selected channel group
➥ While pushing [H/L], push [5
TAG ] for 3 sec. to clear all
tag channels in the channel group.
■ Starting a scan
Set scan type (priority or normal scan) and scan resume timer
in advance using set mode. (p. 38)
q While pushing [H/L], push [DIAL] once or twice to select
the desired channel group, if desired.
w Set tag channels as described at left.
