Inserting the battery pack

Display illumination

Press one of these buttons (MODE and / ) to activate display illumination for approximately 5 seconds.

Coverage (referred to PMR frequency band)

The maximum range depends on terrain condition and is obtained during use in an open space.
The only limitation to maximum possible range are environmental factors such as blockage caused by trees, buildings, or other obstructions. Inside a car or a metallic constructions, the range can be reduced. Normally the coverage in the city, with buidings or other obstructions is about 1 or 2 Km. In open space but with obstructions like trees, leafs or houses the maximum possible range is about 4-6 Km. In open space, without obstructions and in sight, like for example in mountain, the coverage can be more that 10 Km.
