WAR NI NG/SAFETY INF ORMATION

The GX400 is a radio transmitting device.

• Do not transmit near electrical blasting equipment or in explosive atmospheres.

• Do not allow children to operate a radio transmitter unsupervised.

• The antenna used for this radio must be properly installed and maintained and must

provide a separation distance of at least 34 cm (13.4 inches) from all persons and must not be collocated or operated in conjunction with any other antenna or transmitter. Never transmit if any person is closer than the speciﬁed distance to the antenna.

• Changes or modiﬁcations to this product or use of accessories not expressly approved by

GME, or operation of this product in any way other than as provided in the GME Owner’s Manual could void your authority to operate this product.

INTR ODUCT ION

Congratulations. You have just purchased one of the most technically advanced 27 MHz radios in the world.

The GME GX400 is a 27 MHz AM radio that combines both Marine and Citizens Band functions into the one radio. The GX400 has a number of enhanced features including fully user programmable channel scanning, safety channel selection (Channel 88 in marine mode, Channel 8 in CB mode), speaker microphone, two Priority channels and a backlit Liquid Crystal Display (LCD) with dimming function.

With its compact size and IPX7 design it can easily be installed into almost any mounting location in your boat, motor vehicle, motor cycle etc.

Please read this manual thoroughly to ensure you get the best from the GX400’s features.

For users in New Zealand, United States of America, Canada, South Africa or Papua New Guinea, please refer to amendment for local frequencies, channel allocations and licensing requirements.

INSTALLATI ON GUIDELINES

• Do not install the radio near an airbag or in an area where an airbag may deploy. If an

airbag is obstructed by the radio, it may not deploy as expected. It could also propel the radio with enough force to cause serious injury.

• Avoid touching the heat sink at the rear of the radio while the radio is in use. The heat sink

can become hot during prolonged use.

• Do not install the radio in front of a vehicle heater. The radio requires a cool airﬂow over the

rear heat sink when transmitting to maintain efﬁciency.

• Do not make unapproved modiﬁcations to the radio. Such modiﬁcations could void the

warranty and cause the radio to operate outside its approved speciﬁcations.

SWIT CH IN G BAND S

The GX400 is capable of operating on both the Australian 27 MHz Marine Band and the Australian 27 MHz Citizens Band. This makes your radio very versatile in that it can be used in your vehicle, on a boat or even on a motorcycle or tractor.

When you ﬁrst install your GX400, it should default to the 27 MHz Marine Band. When operating on the Marine Band the radio will display channels 68 – 98 and the 88 key will default to safety Channel 88.

To select the CB band, turn the radio OFF, then press and hold the DW key while turning the radio on again. The radio will now display channels

Repeat the sequence above to return to the Marine Band.

NOTE: Class licence 2001 prohibits the use of a Maritime Ship Station for land-based

communications. When the Marine Band is selected, the GX400 should only be used for Ship-to-Ship, Ship-to-Shore or Shore-to-Ship communications.

GENER AL O PERATION

VOLUME ON/OFF

To turn the GX400 on, brieﬂy press the

To adjust the volume, rotate the volume control. Rotate the volume control clockwise to increase the volume or counter-clockwise to reduce the volume.

NOTE: At minimum volume setting there is still sufﬁcient volume to be heard in a quiet cabin

environment.

To turn the GX400 off, press and hold the

SQUELCH CONTROL

The squelch control is used to eliminate the background noise when there are no signals present. To adjust the squelch, ﬁrst rotate it fully counter-clockwise until the background noise is heard, then slowly rotate it clockwise until the noise disappears. If there are signals on the channel, you should wait until the channel is clear (or select a quiet channel) before adjusting the squelch.

Once adjusted, the receiver will remain quiet as long as there are no signals present, but an incoming signal will override the squelch and be heard in the speaker. As the control is advanced further clockwise the squelch action is progressively increased and stronger incoming signals are needed to override it. To receive very weak signals or to disable the squelch, simply turn the control fully counter-clockwise.

CHANNEL SELECTION

Select the required channel by brieﬂy pressing the displayed on the LCD. Press and hold either key to quickly advance upwards or downwards through the channels. Release the key when the required channel is displayed.

key to cycle through the display brightness settings. The display brightness will cycle through Off, Dim and Bright. If the radio is switched off the selected brightness level will be retained in memory and will be restored when the radio is switched on again.

TRANSMITTING

To transmit, press the PTT on the microphone. Hold the microphone 2 – 6 cm from your mouth and slightly to one side so your voice does not project directly into the microphone. Speak at a normal voice level. Your GX400 has a build-in speech processor which automatically controls the level of your transmitted voice. It is not necessary to raise your voice or shout into the microphone. Release the PTT to receive.

NOISE LIMITER

The NL key activates an extremely effective noise limiter circuit which helps to eliminate most electrical impulse interference caused by engine ignition systems etc. This allows clearer reception of weak signals even under noisy electrical conditions. When the noise limiter is selected, ‘NL’ is displayed on the LCD.
