PRECAUTION  
BE CAREFUL! The IC-M88 employs waterproof con-  
struction, which corresponds to JIS waterproof specification,  
Grade 7 (1 m; 3 ft depth for 30 min.). However, once the  
transceiver has been dropped, waterproofing cannot be guar-  
anteed due to the fact that the transceiver may be cracked,  
or the waterproof seal damaged, etc.  
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  
(2 to 4 inches) away from the lips and the transceiver is verti-  
cal.  
MAKE SURE the flexible antenna and battery pack are  
securely attached to the transceiver, and that the antenna and  
battery pack are dry before attachment. Exposing the inside  
of the transceiver to water will result in serious damage to the  
transceiver.  
NEVER connect the transceiver to a power source other  
than the BP-226 or BP-227. Such a connection will ruin the  
transceiver.  
For U.S.A. only  
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): Marine, below –30°C (–22°F) or above  
+60°C (+140°F): LMR.  
CAUTION: Changes or modifications to this device, not  
expressly approved by Icom Inc., could void your authority to  
operate this device under FCC regulations.  
KEEP the transceiver out of the reach of children.  
KEEP the transceiver at least 0.9 meters (3.0 ft) away from  
your vessel’s magnetic navigation compass.

OPERATING RULES  
1
(2) OPERATOR’S LICENSE  
D Priorities  
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.  
• 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.  
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.  
You must monitor Channel 16 when you are not operating  
on another channel.  
• False or fraudulent distress calls are prohibited under law.  
However, non-licensed individuals may talk over a transceiver  
if a licensed operator starts, supervises, ends the call and  
makes the necessary log entries.  
D Privacy  
• Information overheard but not intended for you cannot law-  
fully be used in any way.  
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 regulations.  
• Indecent or profane language is prohibited.  
D Radio licenses  
(1) 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 in-  
cludes the call sign which is your craft’s identification for radio  
purposes.  
NOTE: Even though the IC-M88 is capable of operation  
on VHF marine channels 3, 21, 23, 61, 64, 81, 82 and 83,  
according to FCC regulations these simplex channels can-  
not be lawfully used by the general public in USA waters.

I Scan types  
Scanning is an efcient way to locate signals quickly over a  
wide frequency range. The transceiver has priority scan and  
normal scan.  
Set the tag channels (scanned channel) before scanning.  
Clear the tag channels which inconveniently stop scanning,  
such as digital communications.  
In addition, the weather alert and auto scan function is avail-  
able for standby convenience. These functions can be acti-  
vated simultaneously, depending on the settings in SET  
mode. (pgs. 18, 19)  
Choose priority or normal scan in SET mode. (p. 18)

Normal scan, like priority scan, searches through all tag  
channels in sequence. However, unlike priority scan, Chan-  
nel 16 is not checked unless Channel 16 is set as a tag  
channel.  
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.

BATTERY CHARGING  
9
I Battery charging  
Prior to using the transceiver for the first time, the battery  
pack must be fully charged for optimum life and operation.  
I Cautions  
NEVER incinerate used battery packs. Internal battery gas  
may cause an explosion.  
NEVER immerse the battery pack in water. If the battery pack  
becomes wet, be sure to wipe it dry immediately (particularly  
the battery terminals) BEFORE attaching it to the transceiver.  
Otherwise, the terminals will become corroded, or cause con-  
nection failure, etc.  
CAUTION: To avoid damage to the transceiver, turn it OFF  
while charging.  
Recommended temperature range for charging:  
+10°C to +40°C (+50°F to +104°F)  
- The Li-Ion battery is functioning within 20°C to +60°C  
(4°F to +140°F)  
Use the specified chargers (BC-119N, BC-121N and BC-  
152). NEVER use another manufacturers charger.  
Use the supplied AC adapter (BC-147A/E) for BC-152.  
NEVER use another manufacturers AC adapter.  
NEVER short the terminals of the battery pack. Also, current  
may ow into nearby metal objects, such as a necklace, etc.  
Therefore, be careful when carrying with, or placing near  
metal objects, carrying in handbags, etc.  
AVOID leaving the battery pack in a fully charged, or com-  
pletely discharged condition for long time. It causes shorter  
battery life. In case of leaving the battery pack unused for a  
long time, it must be kept safely after discharge, or use the  
battery until the battery indicator shows the middle level, then  
remove it from the transceiver.  
Recommendation:  
If your battery pack seems to have no capacity even after  
being charged, completely discharge it by leaving the power  
ON overnight. Then, fully charge the battery pack again. If the  
battery pack still does not retain a charge (or very little), a  
new battery pack must be purchased.  
Charge the supplied battery pack for a maximum of  
up to 10 hours. Li-Ion batteries are different from Ni-  
Cd batteries in that it is not necessary to completely  
charge and discharge them to prolong the battery life.  
Therefore, charging the battery in intervals, and not  
for extended periods is recommended.
