TALKING AND LISTENING

Your radio has 8 channels and 38 interference eliminator codes. If you are in a group and you wish to talk to each other, all radios must be set to the same channel and code. If you experience interference and need to change channel, ensure that you change the channel and code of all radios in your group. To talk to others using the radio:

1.Hold radio 5 to 7 centimetres from mouth.

2.Press and hold PTT and speak into the microphone.

The is displayed continuously whilst transmit- ting.

3.After speaking, release PTT. You can now receive incoming calls. Whilst receiving, the is displayed.

Talk Range

Your radio has been designed to maximize performance and improve transmission range in the field. It is recommended that you do not use the radios closer than 1.5 meters apart, to avoid interference.

Talk range depends on the terrain. It will be affected by concrete structures, heavy foliage and by operating radios indoors or in vehicles.

Optimal range occurs in flat, open areas, with up to 8 kilometres of coverage, if possible. Medium range occurs when buildings and trees are in the way.

Minimal range occurs when dense foliage and mountains obstruct the communication path.

Monitoring Channel Activity

It is good radio etiquette to monitor the channel for activity before you transmit, to ensure that you do not interrupt other users already on the channel.

1.To monitor briefly, press and release MON. A flash-

ing will be displayed. If you hear static, the chan- nel is clear for use. Obstacles that block the signal path may affect the strength of the incoming signal.

2.To monitor continuously, press and hold MON for 2 seconds. The will continue to flash. Both the static noise and any signals will be heard.

3.To turn the monitor off, press MON, the will no longer be displayed.
