0. 
NOTE: 
To 
meet the  European GMDSS regulations 
(ETS300 
338,  ETS300 373), the following  must 
be

PRECAUTIONS 
Lt 
WARNING! 
NEVER 
connect the transceiver 
to 
an 
AC outlet directly.  This may pose a fire hazard 
or 
result 
in 
an electric shock. 
Lt 
WARNING! 
NEVER 
mount the transceiver 
overhead.  The weight of the transceiver is approxi-
mately  8 
kg, 
but  its  apparent  weight  will  increase 
several  fold  due  to  wave  shocks  or vibration.  The 
transceiver must 
be 
mounted 
on 
a flat  hard  surface 
only. 
NEVER 
connect a power source of more than  16 V 
DC 
such as a 24 V  battery.  This connection will  ruin 
the transceiver. 
NEVER 
place the transceiver where normal opera-
tion of the ship or 
vehicle may 
be 
hindered or where it 
could cause bodily injury. 
NEVER 
allow children to touch the transceiver. 
NEVER 
expose the transceiver to rain, snow or any 
liquids. 
There are two types  of grounding  systems  available 
for  the  IC-M71 0  - Negative  Ground  and  Floating 
Ground -
NEVER 
install the negative ground type 
to  a  plus-grounding  ship. 
Such  a  connection  might 
blow fuses and is not usable.

WARNING 
Personal 
injury, 
fire 
hazard 
or

shock 
may 
occur.

NOTE 
risk 
of 
personal 
injury, 
fire 
or 
electric 
shock 
. 
NOTE: The IC-M710 GMDSS version has a high-sta-
bility crystal oscillator unit. This unit draws a slight cur-
rent even  when  power to the transceiver is 
OFF. 
To 
prevent battery exhaustion when  docking your vessel 
for extended periods, unplug the 
DC 
cable from the 
DC 
power receptacle. 
DO  NOT 
use  chemical  agents  such  as  benzene  or 
alcohol  when  cleaning,  as  they  can  damage  the 
transceiver surfaces. 
In 
maritime  mobile  operation,  KEEP the  transceiver 
and  microphone 
as far away as  possible  (at least 1 
m) 
from the magnetic navigation compass to prevent 
erroneous indications. 
USE 
an 
lcom  microphone  and/or  handset  only 
(supplied 
or optional).  Other brands may have differ-
ent  pin  assignments  and  may  damage  the  trans-
ceiver. 
AVOID using or placing the transceiver 
in 
areas with 
temperatures 
below 
-20 
oc 
( 
-4 
•F)  or above +60 
°C 
(+140.F). 
AVOID 
connecting the transceiver to a power source 
using  reverse 
polarity.  This connection  will  not only 
blow 
fuses but may also damage the transceiver. 
AVOID  placing  the  transceiver 
in 
excessively  dusty 
environments 
or 
in 
direct sunlight. 
AVOID  placing 
the transceiver against walls  or putt-
ing  anything  on  top  of  the  transceiver.  This 
will 
obstruct heat dissipation.
