Operation

Switching on/off and adjusting the volume
Turn the power/volume dial clockwise to switch on the radio.
Turn the control clockwise or counterclockwise to adjust the volume
as needed.
Turn the control counter-clockwise until you hear a me- chanical
"click" to switch off the radio.
Send
To be able to communicate with each other, all radios in your
group must be set to the same channel.
Press the monitor key briefly to activate the monitor function. This
allows you to check whether the channel is occupied.
Then press the PTT button to transmit and release the PTT button to
receive.
During radio communication, only one partner can speak at a
time. Therefore, do not transmit yourself when you hear a partner.
Only transmit as little as possible so that the channel remains
free.
A lot of power is consumed when sending. Therefore, keep your
transmission time as short as possible so that the battery lasts
longer. If you cannot reach a partner that you can normally receive
without problems, they may be using CTCSS tones or DCS codes.
Monitor
The monitor function allows you to temporarily deactivate the
squelch function in order to receive signals that are too weak to
be heard when the squelch function is activated.
Briefly press the monitor key to activate or deactivate the function.
