CAUTION: DO NOT place the transceiver against
walls or putting anything on top of the transceiver.
This may overheat the transceiver.
BE CAREFUL! The transceiver main unit will become
hot when operating the transceiver continuously for
long periods of time.
BE CAREFUL! The remote controller’s front panel
meets IPX7* requirements for waterproof protection.
However, once the transceiver has been dropped,
or the waterproof seal is cracked or damaged,
waterproof protection cannot be guaranteed because
of possible damage to the case or the waterproof
seal.
* The connectors on the rear panel do not meet IPX7.
NOTE: The LCD display may have cosmetic
imperfections that appear as small dark or light spots.
This is not a malfunction or defect, but a normal
characteristic of LCD displays.

OPERATING RULES
• CALL PROCEDURE
Calls must be properly identied and the time limit
must be respected.
1. Give your call sign each time you call another
ship or coast guard station. If you have no call
sign, identify the station by giving your ship name
and the name of the licensee.
2. Give your call sign at the end of each
transmission that lasts more than 3 minutes.
3. You must break and give your call sign at least
once every 15 minutes during long ship-to-shore
calls.
4. Keep your unanswered calls short, less than 30
seconds. Do not repeat a call for 2 minutes.
5. Unnecessary transmissions are not allowed.
• PRIORITIES
1. Read all rules and regulations pertaining to
priorities and keep an up-to-date copy handy.
Safety and Distress calls take priority over any
other calls.
2. False or fraudulent Distress signals are prohibited
and punishable by law.
• PRIVACY
1. Information overheard but not intended for you,
cannot lawfully be used in any case.
2. Indecent or profane language is prohibited.
• LOGS
1. All Distress, Emergency and Safety calls must
be recorded in complete details. Log data activity
is usually recorded for 24 hours. Universal Time
Coordinated (UTC) is frequently used.
2. Keep adjustments, repairs, channel frequency
changes and authorized modications affecting
electrical operation of the equipment in the
maintenance log. The entries requires signatures
by the authorized licensed technician performing
or supervising the work.
• RADIO LICENSES
(1) SHIP RADIO STATION LICENSE
You need a current ship radio station license before
using the transceiver. It is unlawful to operate a ship
radio station which is not licensed, but required to be.
If required, contact 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 identication
for radio communication 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.
If required, the Restricted Radiotelephone Operator
Permit must be posted or kept with the operator. If
required, 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.
A current copy of the applicable government rules
and regulations 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.
NOTE: Before transmitting, monitor the channel you
want to use to avoid interrupting communications
already in progress.
