INT RODUCTION

Congratulations on purchasing this GME fully featured VHF
Marine radio.

Your GX660 has been built to offer excellent value by
combining advanced features, great design and manufacturing
quality.

To ensure you are familiar with the operation and features of
your radio and in order to obtain the best performance, please
read this manual thoroughly before operation.

CAUTION

READ ALL INSTRUCTIONS carefully and completely
before operating your radio and retain this manual for future
reference.

NEVER: connect the radio to a power source other than the
supplied battery. This may damage your product.

NEVER: transmit with the antenna less than 5 cm from
exposed parts of the body.

NEVER: use the radio in or near a mining facility or other area
which uses remotely triggered explosives or an area labelled
‘Blasting Area’.

NEVER: use or charge your radio in a potentially explosive
atmosphere.

DO NOT: place your radio in front of a vehicle air bag.

DO NOT: operate your radio on board an aircraft.

DO NOT: use your radio with a damaged antenna.

DO NOT: attempt to modify your radio in any way.

ALWAYS: charge your radio at normal room temperature.

ALWAYS: switch off your radio where notices restrict the use

of two-way radio or mobile telephones.

AVOID: storing or charging your radio in direct sunlight.

AVOID: storing or using your radio where temperatures are

below -15º C or above +55º C.

WATERPROOF (IPX7)

The GX660 is waterproof and meets IPX7 rating (see www2.
gme.net.au/IPRatings for standards chart). However, if the
GX660 is dropped, waterproofing cannot be guaranteed due
to the fact that damage to the external chassis may occur.

ANTENNA AND BATTERY PACK

Make sure the flexible antenna and battery pack are securely
attached to the GX660 and that the antenna and battery pack
are dry before attachment. Exposing the inside of the GX660
to water will result in serious damage to the radio.

ELECTRONIC RECYCLING

Please ensure this unit is disposed of correctly when no longer
required for use.

SA F E TY INSTRUCTIONS

Please read through this manual before the first operation. If
you have any questions, please contact GME service or your
local dealer.

Extensive exposure to heat may result in damage to the radio.

Connection to the power source with reversed polarity will
damage the radio severely. This damage is not covered by the
warranty.

Do not disassemble.

Avoid overheating which may cause loss of contrast and in
extreme cases, a darkening of the screen. Problems which
occur from over heating are reversible when the temperature
decreases.

IN CASE OF EMERGENCY

If your life or the safety of your vessel is in imminent
danger you should contact other vessels in your
area or the Coast Guard by sending a distress call on
Channel 16.

USING THE CHANNEL 16 DISTRESS CALL PROCEDURE

1. “MAYDAY MAYDAY MAYDAY.”

2. “THIS IS ...........................” (name of vessel)

3. Your call sign or other indication of the vessel.

4. “LOCATED AT .....................” (your position)

5. The nature of the distress and assistance required.

6. Any other information which might facilitate
the rescue.

OPERATOR QUALIFICATIONS

Any person in Australia operating a VHF marine radio should
possess at least a Marine Radio Operators VHF Certificate of
Proficiency (MROVCP). Alternatively, operators may obtain a
Marine Radio Operators Certificate of Proficiency (MROCP),
which covers the operation of both VHF and MF/HF equipment.

Many TAFEs and marine organisations offer courses leading
to examination for the MROVCP and MROCP although such
courses are not compulsory. Persons wishing to obtain the
MROVCP or MROCP should first purchase a copy of the
Maritime Radio Operator Handbook which is essential reading
for every boat owner in Australia.

The Australian Maritime College (AMC) provides the marine
examination and certificate service on behalf of the ACMA. The
AMC can provide the details of organisations and individuals
offering courses and/or conducting exams.

INTERNATIONAL CUSTOMERS

Local requirements will vary throughout the world with regard
to operator qualification.

International customers should contact their local regulatory
body.

BATTERY OPTIONS

The GX660 comes with a Li-Ion (Lithium Ion) rechargeable
battery. The GX660 battery pack will provide convenient, long
life service, and will operate your radio for approximately 12
hours on a single charge. The length of service depends largely
on how much time you spend transmitting, and what transmit
power you use.

Charging

A feature of the Li-Ion pack is that you can recharge at any
time. The standard charger will completely recharge the GX660
battery pack in approximately 12 hours. The GX660 radio can
be used with the charger attached or removed. The GX660 will
not be damaged by extended charge times. When the radio is
connected to the charger and power is present, the LED on the
outside of the charger will be red. When battery is fully charged
the ‘LED’ will turn to green.

NOTE: The battery charger does not act as a primary
power source.

Battery pack assembling instructions

When you insert the battery pack, make sure you follow the
directions on page 18. Otherwise, the radio will not work.

ATTENTION

The battery for your GX660 has been factory installed. Caution
should be exercised opening the battery compartment as the
water tight integrity of the radio could be compromised if not
properly assembled. Applying a thin coat of organic vegetable
oil to the 0-ring may assist in assembly.

Maintenance and caution

The GX660 is designed to provide years of trouble free
operation with virtually no maintenance. Follow these simple
procedures to ensure that the GX660 continues to deliver top
performance:

• Rinse the GX660 lightly with fresh water after exposure to
salt water or the radio’s keys may become inoperable due to
salt crystallisation.

• BE CAREFUL! Extreme shock (dropping, etc.) may crack the
case or dislodge or damage the seals. Additionally, wear or
improper battery pack installation can damage the battery
compartment seal.

• Never transmit without an antenna attached to avoid any

damage to the radio.

• Avoid using or placing the GX660 in areas with temperature

below -15°C or above + 55°C. Do not place on windshields,
etc.
