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.
