SDM630 DMR TIER II – OPERATING INSTRUCTIONS

SAFETY

1. Do NOT operate your radio, without a hands free kit, whilst driving a vehicle.

2. Do NOT operate your radio in an explosive atmosphere.

Obey the 'Turn Off Two-way Radios' signs where these are posted, e.g. on a

petrol station forecourt.

3. Do NOT touch the antenna while the radio is transmitting.

HINTS FOR USING THE RADIO

• When speaking, hold the microphone a few centimetres from your mouth and speak

across it, rather than into it.

• Keep the length of your conversation to a minimum and replace the microphone on its

cradle after use.

• When it is possible to move location, avoid making calls from known poor signal-strength

areas such as the radio systems fringe areas (limit of range) or from screened or

shadowed areas, e.g. an underground car park or underpass.

• To avoid unnecessary drain on the vehicle battery, keep the engine running when using

the radio for extensive periods of time.
