4. Before start-up
4.1. Setting the digital code
Please check whether both devices are set to
the same channel and to the same digital code
before using the transmitter and receiver. Open
both battery compartment lids to set the digital
code. Pull the battery compartment lid belt clips
downwards until they are audibly released from
the fi xtures and tilt them upwards by approx. 30°
until they can be adjusted. The battery compart-
ment lids are now pushed in the direction of the
arrow and removed from the housing.
You can now change the position of the DIP-
switch (2) (see "12. Digital code combination
table") using a ballpoint-pen.
The switch position must be identical in both de-
vices to accomplish a connection.
4.2. Inserting the rechargeable batteries
Position the device with the rear side towards
you, pull the battery compartment lid belt clips
downwards until they are audibly released from
the fi xtures and tilt them upwards by approx. 30°
until they can be adjusted. The battery compart-
ment lids are now pushed in the direction of the
arrow and removed from the housing.
Insert the enclosed Micro rechargeable bat-
teries AAA, while observing the correct polarity
