RF RADIATION INFORMATION
RF RADIATION PROFILE
Your radio is designed and tested to comply with a number
of national and international standards and guidelines
(listed below) regarding human exposure to radio frequency
electromagnetic energy. This radio complies with the IEEE
and ICNIRP exposure limits for occupational/controlled RF
exposure environment at operating duty factors of up to 50%
transmitting and is authorised by the FCC for occupational
use only. In terms of measuring RF energy for compliance with
the FCC exposure guidelines, your radio radiates measurable
RF energy only while it is transmitting (during talking in PTT
mode), not when it is receiving (listening) or in standby mode.
The device complies with SAR and/or RF field strength limits of
RSS-102 requirements.
RF RADIATION SAFETY
In order to ensure user health, experts from relevant industries
including science, engineering, medicine and health work
with international organizations to develop standards for safe
exposure to RF radiation. These standards consist of:
•United States Federal Communications Commission, Code
of Federal Regulations; 47CFR part 2 sub-part J;
•American National Standards Institute (ANSI)/Institute of
Electrical and Electronic Engineers (IEEE) C95. 1-1992;
•Institute of Electrical and Electronic Engineers (IEEE) C95.
1-1999;
•International Commission on Non-Ionizing Radiation
Protection (ICNIRP) 1998;
FCC Regulations
Federal Communication Commission (FCC) requires that all
radio communication products should meet the requirements
set forth in the above standards before they can be marketed
in the US, and the manufacturer shall post a RF label on the
product to inform users of operational instructions, so as to
enhance their occupational health against exposure to
RF energy.
Part 15 Compliance
This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful
interference to radio communications.
However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of
the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and
receiver.
•Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician
for help. Note: ’Changes or modifications to this unit not
expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.’
EU Regulatory Conformance
As certified by the qualified laboratory, the product is in
compliance with the essential requirements and other relevant
provisions of the Directive 1999/5/EC. Please note that the
above information is applicable to EU countries only.

OPERATING RULES
Priorities
•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.
•You must monitor Channel 16 when you are not operating
on another channel.
•False or fraudulent distress calls are prohibited under law.
Privacy
•Information overheard but not intended for you cannot
lawfully be used in any way.
•Indecent or profane language is prohibited.
RADIO OPERATOR QUALIFICATIONS
A certificate of proficiency is required to operate a VHF marine
radio. The certificate shows that the holder understands distress
and safety procedures, knows how to respond to an emergency
call and helps to ensure that your messages are understood by
others.
The minimum qualification is generally the Short Range
Operators VHF Certificate of Proficiency (SROCP) however in
Australia a new Australian Waters Qualification (AWQ) has
been introduced for marine radio users who only operate VHF
marine radios in Australian Territorial Waters.
A person who doesn’t hold a certificate may operate a VHF
radio if they are in the immediate vicinity of the certified
operator and radio so that they can step in and take over if
necessary
Persons operating a VHF marine radio without holding an
appropriate qualification or being under the supervision of an
appropriately qualified person, may be breaching the Radio
communications Act.
RANGE
The range of VHF transmissions depends on antenna height,
transmitter power and the terrain over which the signals
pass. For a 5 watt handheld radio like the GX625, ship
to ship communications up to 5 nautical miles should be
possible. Using an external antenna should allow ship to ship
communication of 8 nautical miles or more. Ship to shore
ranges will often be greater due to the increased height of the
shore antenna.
CHARGING THE BATTERY PACK
The GX625 has a rechargeable 1200mAh Li-Ion battery pack.
To charge the battery, plug the AC charger unit into the mains
supply and plug the DC connector into the charging cradle.
Place the GX625 into the cradle for charging. The battery
should charge in around 2 hours.
Removing the battery pack
To remove the battery pack, lift the locking lever at the base of
the battery pack and rotate. Lift the battery pack from the base
of the radio and slide the battery pack away from
the radio.
To re-fit the battery pack, slide the top of the battery pack
in towards the radio then press the base of the battery pack
downwards against the battery contacts. Rotate the battery
lever upwards and press into place so that it clicks firmly.

while still being able to receive important broadcasts on
Channel 16.
To use the Dual Watch function;
1. Press the or keys to select your preferred
working channel.
2. Briefly press the key to activate Dual Watch. ‘DW’ will
be displayed and the channel number will quickly alternate
between 16 and the selected channel.
•If a signal is received on the selected channel, the Dual
Watch will pause on the selected channel to allow the signal
to be heard but will continue to monitor channel 16 every 2
seconds resulting in short breaks in the conversation. Once
the signal has gone, Dual Watch continues.
•If a signal appears on channel 16 the radio will lock onto
channel 16 and signals on channel 16 will have priority over
any signals on the selected channel.
3. To cancel Dual Watch, briefly press the key.
TRIPLE WATCH
The Triple Watch function is a 3 channel scan feature where
the radio switches between Channel 16, your selected channel
and a second priority channel. This allows you to monitor 2
channels while still being able to receive important broadcasts
on Channel 16.
NOTE: Prior to using Triple Watch you will need to have
programmed your second priority channel (see Second Priority
Channel further above).
To use the Triple Watch Function
