water even when the supplied accesso-
ries are attached.
 •Whenathird-partybatterypack,strap,an-
tenna, and so on is used, it may sink.
☞Floats and flashes
When the transceiver detects that it has
come in contact with water, the LCD
backlight, keys and trim start to blink,
making it easy to find the transceiver
even at night or in a dark environment.

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.Say your call sign or other indication of the vessel (AND
your 9-digit DSC ID, if you have one).
4.“LOCATED AT ...............” (your position).
5.State the nature of the distress and assistance re-
quired.
6.Give any other information which might facilitate the
rescue.
USING DIGITAL SELECTIVE CALLING (Ch 70)
DISTRESS CALL PROCEDURE
1.While lifting up the key cover, hold down [DISTRESS] for
3 seconds until you hear 3 short beeps and then one long
beep.
2.Wait for an acknowledgment on Channel 70 from a coast
station.

RECOMMENDATION
CLEAN THE TRANSCEIVER THOROUGHLY WITH FRESH
WATER after exposure to saltwater. Otherwise, the trans-
ceiver's keys, switches and controllers may become inoper-
able due to salt crystallization.
NOTE: DO NOT wash the transceiver in water if there is any
reason to suspect the waterproofing may not be effective. For
example, in cases where the battery pack rubber seal is dam-
aged, the transceiver/battery pack is cracked or broken, or
has been dropped, or when the battery pack is detached from
the transceiver.
RWARNING! NEVER connect the transceiver to an
AC outlet. This may pose a fire hazard or result in an electric
shock.
RWARNING! NEVER hold the transceiver so that
the antenna is very close to, or touching exposed parts of
the body, especially the face or eyes, while transmitting. The
transceiver will perform best if the microphone is 5 to 10 cm
away from the lips and the transceiver is vertical.
RWARNING! NEVER operate the transceiver with
other audio accessories at high volume levels. Hearing ex-
perts advise against continuous high volume operation. If you
experience a ringing in your ears, reduce the volume level or
discontinue use.
DO NOT modify the transceiver. The transceiver warranty does
not cover any problems caused by unauthorized modification.
BE CAREFUL! The transceiver will become hot when
operating it continuously for long periods of time.
KEEP the transceiver and microphone at least 1 m away
from the vessel’s magnetic navigation compass.
KEEP the transceiver out of the reach of children.
PRECAUTIONS

iv
PRECAUTIONS
CAUTION: MAKE SURE the flexible antenna, bat-
tery pack and jack cover are securely attached to the trans-
ceiver, and that the antenna and battery pack are dry before
attachment. Exposing the inside of the transceiver to dust or
water will result in serious damage to the transceiver.
DO NOT operate the transceiver near unshielded electri-
cal blasting caps or in an explosive atmosphere.
DO NOT push [PTT] when not actually intending to transmit.
DO NOT use or place the transceiver in direct sunlight or
in areas with temperatures below –15°C or above +55°C.
The basic operations, transmission and reception of the
transceiver are guaranteed within the specified operating
temperature range. However, the LCD display may not be
operate correctly, or show an indication in the case of long
hours of operation, or after being placed in extremely cold
areas.
DO NOT use harsh solvents such as benzine or alcohol
when cleaning, as they will damage the transceiver surfaces.
BE CAREFUL! The IC-M91D meets IPX7* requirements
for dust-tight and waterproof protection. However, once the
transceiver has been dropped, dust-tight and waterproof pro-
tection cannot be guaranteed because of possible damage to
the transceiver’s case or the waterproof seal.
* Only when the jack cover or the optional HM-167 is at-
tached.
Even when the transceiver power is OFF, a slight current still
flows in the circuits. Remove the battery pack or batteries
from the transceiver when not using it for a long time. Other-
wise, the installed battery pack or batteries will become ex-
hausted, and will need to be recharged or replaced.
BE CAREFUL! Even if the volume level is set low, the
beeps of the Float ’n Flash, DSC alarm and AquaQuake func-
tions are very loud.
MAKE SURE to turn the transceiver power OFF before
connecting the supplied/optional equipment.

Radio licensesD
(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 opera-
tor may operate a transceiver.
However, non-licensed individuals may talk over a transceiv-
er if a licensed operator starts, supervises, ends the call and
makes the necessary log entries.
A current copy of the applicable government rules and regu-
lations 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 regula-
tions.

IMPORTANT: Prior to using the transceiver for the first
time, the battery pack must be fully charged for optimum
life and operation. To avoid damage to the transceiver,
turn the power OFF while charging.
Channel 16D
Channel 16 is the distress and safety channel. It is used for
establishing initial contact with a station and for emergency
communications. Channel 16 is monitored during both Dual-
