Instructions

Adjusting the volume

(factory setting: level 3)

4 volume levels are available (schema: 1

µ2 µ3 µ4 µ3 µ2 µ1). Select

the requested volume level by means of the volume key: a beep sounds

and the LED is blinking according to the selected level (e.g. volume

level 4: LED is blinking 4x).

Transmitting

Hold the PTT button pressed and speak with normal voice level and

a distance of approx. 5 cm into the microphone. If your message is

finished, release the PTT key.

Receiving a signal

When the radio set is switched on, it is ready-to-receive (unless the

set is transmitting). If a signal is received on the adjusted channel, the

LED is blinking for about 2 seconds.

Automatic squelch

Your radio set is equipped with an automatic squelch that prevents

that an annoying noise can be heard on free radio channels. However,

under certain conditions  and depending on the distance - computers,

electric or electronic devices might interfere with this squelch, so that

you hear noises. Due to the supersensitive receiver of the radio set,

such interferences in immediate proximity are normal and unavoidable.

In case of such interferences you should change the distance to the

source of interference and hold the radio set in such a manner that

the antenna could send freely.

Battery save mode / Battery low indication

The power consumption of the radio is very small. If no signal is received,

the electronic battery stand-by mode is activated. If the capacity of the

batteries is too low, the LED is at first blinking every 3 seconds, and

then it is blinking every second. Finally a beep sounds and the radio

turns off. Now you have to replace the batteries.

Notes: It is essential to ensure the indicated polarity when inserting

the batteries into the battery case! In case of a battery change you

always have to exchange all batteries. Do not mix different battery

types, batteries with different capacities or batteries and rechargeable

battery cells!
