INSTRUCTION MARINE IMPORTANT EXPLICIT DEFINITIONS
READ THIS INSTRUCTION MANUAL CAREFULLY The explicit definitions described below apply to this
before attempting to operate the transceiver instruction manual
SAVE THIS INSTRUCTION MANUALThis manual WORD DEFINITION
contains important safety and operating instructions for Personal injury fire hazard or electric
RWARNING shock may occur
the ICM710RT MFHF MARINE TRANSCEIVER
CAUTION Equipment damage may occur
If disregarded inconvenience only No risk
NOTE of personal injury fire or electric shock
NOTE The version has a
crystal oscillator unit This unit draws a
slight current even when power to the transceiver
is OFF To prevent battery exhaustion when dock
ing your vessel for extended periods unplug the
DC cable from the DC power PRECAUTIONS
RWARNING NEVER connect the transceiver to an DO NOT use chemical agents such as benzene or al
AC outlet directly This may pose a fire hazard or re cohol when cleaning as they can damage the trans
sult in an electric shock ceivers surfaces
RWARNING NEVER mount the transceiver over In maritime mobile operation KEEP the transceiver
head The weight of the transceiver is approximately 8 and microphone as far away as possible at least 1 m
kg but its apparent weight will increase several fold from the magnetic navigation compass to prevent er
due to wave shocks and vibration The transceiver roneous indications
must be mounted on a flat hard surface only
USE an Icom microphone andor handset only sup
NEVER connect a power source of more than 16 V DC plied or optional Other brands may have different pin
such as a 24 volt battery This connection will ruin the assignments and may damage the transceiver
transceiver
AVOID using or placing the transceiver in areas with
NEVER place the transceiver where normal operation temperatures below 20C 4F or above 60C
of the ship or vehicle may be hindered or where it 140F
could cause bodily injury
AVOID connecting the transceiver to a power source
Place unit in a secure place to avoid inadvertent use using reverse polarity This connection will not only
by children blow fuses but may also damage the NEVER expose the transceiver to rain snow or any
AVOID placing the transceiver in excessively dusty en
liquids vironments or in direct sunlight
There are two types of grounding systems available for AVOID placing the transceiver against walls or putting
the Ground and Floating anything on top of the transceiver This will obstruct
GroundNEVER install the negative ground type to a heat dissipation

CALL PROCEDURES LOGS
Calls must be properly identified and time limits must All distress emergency and safety calls must be
be respected recorded in complete detail Log data activity is usu
ally recorded in 24 hour time Universal Time UTC
Give your call sign each time you call another vessel is frequently used
or coast station If you have no call sign identify
your vessel name and the name of the licensee Adjustments repairs channel frequency changes
and authorized modifications affecting electrical op
Give your call sign at the end of each transmission eration of the equipment must be kept in the main
that lasts more than 3 min tenance log entries must be signed by the
authorized licensed technician performing or super
You must break and give your call sign at least once
vising the work
every 15 min during long shiptoshore calls
Keep your unanswered calls short less than 30 sec
Do not repeat a call for 2 min RADIO LICENSES
1 SHIP STATION LICENSE
Unnecessary transmissions are not allowed You must have a current radio station license before
using the transceiver It is unlawful to operate a ship
station which is not licensed

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
