Frequency adjustment:
There are two frequency ranges (EUV232 and EUV243) with 8 adjustable channels each (see point 5,
Frequency list). The range is defi ned by the respective variant and can not be changed.
The channel setting on the receiver is made using the „Channel
/
“ buttons. To avoid unintentional ad-
justment, the buttons are normally locked. To unlock, press both buttons simultaneously for about 5 seconds
until the display fl ashes. Now use the
/
buttons to select the desired channel. After a few seconds, the
display automatically switches from fl ashing mode to permanent mode, the channel is now set and the but-
tons are locked again.
Attention: During adjustment, the microphone should be off because a „busy“ channel can not be selected.
