Troubleshooting
Fault Your radio set cannot be switched on.
Remedy Charge the battery pack or renew the batteries.
Fault You can neither speak nor hear your radio partner.
Remedy Adjust the same channel and possibly the same CTCSS-tone for all radio sets.
If you are out of reach, reduce the distance to your radio partner.
Fault You do hear your radio partner and your partner does not hear you (Micky-Mouse-
effect).
Remedy Make sure that the scrambler is either activated or deactivated for both radio sets.
With an active scrambler both radio sets must be adjusted to the same speech
scrambling code.
Fault No key function
Remedy The key lock is switched on. Deactivate the key lock.
Fault The channel is permanently busy
Remedy The VOX sensitivity of a partner set is adjusted too high, for this reason the radio set
transmits continuously. Reduce the VOX-sensitivity of the device.
Other parties in your environment occupy the channel. Switch to another channel.
