OPE R ATING 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 LICENCES
Ship Station License
When your craft is equipped with a VHF FM radio, you must
have a current radio station licence before using the radio.
It is unlawful to operate a ship station which is not licensed.
Inquire through your dealer or the appropriate government
agency for a Ship-Radiotelephone license. This license
includes the call sign which is your craft’s identification for
radio purposes.
Operators 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. The restricted
Radiotelephone Operator Permit must be posted near the
radio or be kept with the operator.
Only a licensed radio operator may operate a radio. However,
non-licensed individuals may talk over a radio 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.
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 TX800, 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.

When the time out timer activates, the transmission will stop,
and the radio will return to receive mode. Normal operation
will be restored once the PTT is released.
ATIS OPERATION
ATIS stands for Automatic Transmitter Identification System.
ATIS is used to identify a ship or vessel that has made a radio
transmission. The identity of the vessel is sent digitally each
time the radio operator releases the PTT after transmitting.
ATIS is generally used in the inland waterways of Europe
and is only available when the International channel set is
selected.
The use of ATIS requires a unique 9 digit Maritime Mobile
Service Identity or MMSI (note that the ATIS MMSI is
completely separate to the MMSI required for the DSC
functionality included in DSC compatible radios). Radio
operators in Europe who require the ATIS function should
obtain their unique ATIS MMSI from their local Maritime
Authority.
IMPORTANT: Once the ATIS ID has been programmed
into the radio, the ATIS function is enabled and becomes a
permanent part of the radio’s operation. It cannot be disabled
by the user.
Programming the ATIS ID
1. Switch the radio Off.
2. Hold the key while switching the radio On. The
display will show ‘1 –‘ where the left character shows the
position of the ATIS digit within the ATIS ID (e.g. position 1
of 9) and the right flashing character shows the currently
selected value of the ATIS ID digit at that position.

5. Repeat steps 3 & 4 to enter the entire 9 digit ATIS ID.
6. When the last digit is entered you will be prompted
to enter the ATIS ID again (this is to avoid entering an
invalid entry).
7. After entering the correct ATIS ID for the second time,
the ATIS ID will flash then the radio will revert to normal
operation.
NOTE: If the second ATIS entry doesn’t match the first, the
operation will be cancelled and you will need to start again.
CHARGING THE BATTERY
The battery is a built-in design and is not user serviceable. If
the battery requires replacing, the radio should be returned
to GME for service to ensure the waterproof integrity of the
radio is maintained.
To Charge the Battery
Pull the connector cap on the top panel (between the Volume
control and the antenna) to expose the charging socket. Plug
the supplied AC adaptor into the 240V power then connect
the adaptor’s charger plug into the socket on the top of
the radio.
While the charger is connected the display will show the
battery charging state by animating the battery icon.
IMPORTANT: The connector used to charge the GX800 is a
Mini USB type charging at 8V (instead of the customary 5V
normally associated with this connector).
For this reason,
• Do not connect your GX800 charger to other mini USB
devices as damage may occur to your device.
• Do not remove the warning label fi tted to the charging
lead on the GX800 charger.

Intership channels are for communications between ship stations.
Intership communications should be restricted to Channels 6, 8, 72 and
77. If these are not available, the other channels marked for Intership
may be used. Channel 70 is used exclusively for Digital Selective
Calling (DSC) and is not available for regular voice communications.
NOTES
1. Channel 06 may also be used for communications between ship
stations and aircraft engaged in coordinated search and rescue
operations. Ship stations should avoid harmful interference to such
communications on channel 06 as well as to communications between
aircraft stations, ice breakers and assisted ships during ice seasons.
2. Within the European Maritime Area and in Canada, channels 10,
67 and 73 may also be used by the individual administrations
concerned for communication between ship stations, aircraft stations
and participating land stations engaged in coordinated search and
rescue and anti-pollution operations in local areas. Channels 10 or
73 (depending on location) are also used for the broadcast of Marine
Safety Information by the Maritime and Coast Guard Agency in the
UK only.
3. Channel 13 is designated for use on a worldwide basis as a navigation
safety communication channel, primarily for intership navigation safety
communications.
4. Channels 15 and 17 may also be used for on-board communications
provided the effective radiated power does not exceed 1 watt.
5. The use of Channels 75 and 76 should be restricted to navigation
related communication only and all precautions should be taken to avoid
harmful interference to channel 16. Transmit power is limited to 1 watt.

Channel numbers, e.g. (WX1, WX2) etc. have no special
significance but are often designated this way in consumer
equipment. Other channel numbering schemes are also
prevalent.
The order of channels shown is the order they were established
and is slowly becoming less popular over time than a numerical
ordering of channels.
See NATIONAL WEATHER SERVICE MARINE PRODUCTS
VIA NOAA WEATHER RADIO and the NOAA Weather Radio
Homepage for more information.
Additional Information, Frequencies, and Charts.
Frequencies are in MHz. Modulation is 16KF3E or 16KG3E.
Recreational boaters normally use channels listed as Non-
Commercial: 68, 69, 71, 72, 78A.
Channel 70 is used exclusively for Digital Selective Calling
(DSC) and is not available for regular voice communications.
Channels 75 and 76 are reserved as guard bands for Channel
16 and are not available for regular voice communications.
Note that the letter A indicates simplex use of the ship station
transmit side of an international duplex channel, and that
operations are different than international operations on
that channel.
Some VHF transceivers are equipped with an International
– US switch for that purpose. A channels are generally only
used in the United States, and use is normally not recognized
or allowed outside the US The letter B indicates simplex use
of the coast station transmit side of an international duplex
channel. The US does not currently use B channels for simplex
communications in this band.
Boaters should normally use channels listed as Non-
Commercial. Channel 16 is used for calling other stations or
for distress alerting. Channel 13 should be used to contact a
ship when there is danger of collision. All ships of length 20m
or greater are required to guard VHF channel 13, in addition
to VHF channel 16, when operating within US territorial
waters. Users may be fined by the FCC for improper use of
these channels.
