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
identication 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.

accidental blocking of the frequency should your PTT become jammed or be otherwise
pressed accidentally.
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 Identication 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.

TX2720 Instruction Manual
15
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 O.
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 ashing character shows the currently selected value
of the ATIS ID digit at that position.
ATIS ID Digit Value

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 ash then the
radio will revert to normal operation.
Note: If the second ATIS entry doesn’t match the rst, the operation will be cancelled
and you will need to start again.
WATER DISPLACEMENT TECHNOLOGY
WDT allows the GX800W to displace any water trapped in the speaker grill which
traditionally can be dicult to remove. This is achieved by emitting a loud resonant
tone.To activate WDT press and hold the key whilst switching on the GX800W. You
will be prompted with a beep tone and the letter ‘d’ will display. Press to activate
WDT and hold the GX800W face down. A loud tone will emit from the speaker for 15
seconds, displacing any water from the speaker grill. When complete the GX800W
will resume normal start-up operation.It is recommended to use WDT whenever the
GX800W has been submersed in water.
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.

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
eective 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.
