Switching the walkie-talkie on/off

For switching on the walkie-talkie press and hold down the On/Off key. An acoustic signal is issued. The current channel setting appears in the display and the Ready LED flashes.

For switching off the walkie-talkie press and hold down the On/Off key.

Volume control

Press one of the arrow keys to increase or decrease the volume.

Transmitting and receiving

Transmitting After pressing the PTT button, the Ready LED lights up. If the button is pressed longer than 60 seconds, a warning signal is issued. Transmission is interrupted.

Hold the walkie-talkie approx. 5 to 7 cm from your mouth and speak at a normal volume. In order to talk to other subscribers, the respective walkie-talkies must be set to the same channel and CTCSS code.

Receiving Release the PTT button.

Radio signals cannot be received when the PTT button is being pressed.

GB

Selecting a channel

1 x Press the menu key once.

Select the desired channel and confirm with the PTT button.

Channel Frequency (MHz) Channel Frequency (MHz)

1	446.00625	5	446.05625
2	446.01875	6	446.06875
3	446.03125	7	446.08125
4	446.04375	8	446.09375

Selecting the CTCSS code / CDCSS code

All the calls on walkie-talkies which occur within the range of reception are signalled. A condition for this is that all the walkie-talkies are set to the same channel. To prevent mutual interference, a CTCSS code (analogue / 1 - 38) or a CDCSS code (digital / 39 - 121) can be defined for the set channel. 38 CTCSS codes and 83 CDCSS codes can be set per channel.

2 x Press the menu key twice.

Select the CTCSS/CDCSS code and confirm with the PTT button.

Communication between the subscribers is only then possible when both parties are using the same channel and CTCSS / CDCSS code.

An exception is CTCSS/CDCSS code “0”. In the case of this setting, all the calls on the set channel can be heard regardless of the CTCSS/CDCSS code. To be able to participate in the radio communication, it may be necessary to switch from CTCSS/ CDCSS code “0” to the CTCSS/CDCSS code being used.

If you want to communicate with the walkie-talkies which are not using a CTCSS, you must select CTCSS/CDCSS code "0" on your walkie-talkie.

Searching for a channel

Signals are searched for in the eight channels in a continuous cycle. The icon appears in the display. If an active channel is detected, the channel search stops. The Ready LED flashes once per second.

Press the PTT button to enable radio communication.

If the PTT button is not pressed or the channel is inactive, channel search resumes after five seconds.

Start / End global channel search

To execute a “global channel scan”, set the CTCSS/CDCSS code of the output channel to “0”. The output channel is the channel which is set when the channel scan is activated. The scanning routine stops at every channel on which a signal is received, regardless of the code transmitted with the signal.

Start/End the search for a channel

Start / End specific channel search

To execute a “specific channel scan”, set the CTCSS/CDCSS code for each channel to an individual value.

The scanning routine only stops when a signal is received on a channel that matched the value set.

Start/End the search for a channel

Resuming search for a channel

Continue the search for a channel
