Selecting the channel

Eight channels are available.

Press the CH

s/t key and select a free channel. Through a long

keystroke the channels are switched continuously.

Note: Always adjust both radio sets to the same channel!

Transmitting/receiving

Hold the PTT key pressed and speak with normal voice level and a

distance of approx. 5 cm into the microphone, the TX symbol is displayed.

If your message is finished, release the PTT key, the TX symbol is no

longer displayed.

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

set is transmitting). If the radio set receives a signal, the RX symbol

is displayed.

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 can send freely.

Pilot tone process CTCSS

Your radio set is equipped with a pilot tone process, that permits to

address specific individual partner stations or groups or to receive only

calls from the latter.

Note: 38 different tones are available. Make sure that you and your

partner use the same channel and the same pilot tone.
