Nameplate illumination
This radio doorbell transmitter is equipped with an automatic nameplate illu-
mination which switches on automatically when it is dark and switches off again
when it is bright.
Note: The nameplate illumination only works if the radio doorbell transmitter is
operated with an external power supply.
Replacing the inscription field
The inscription field can be easily replaced. As shown in Fig. 1, carefully use a suit-
able flat-blade screwdriver on the side of the nameplate and lever it forward
without damaging the housing. Underneath is the inscription field, which can
now be easily replaced.

• BELL-501 TX: 52mm x 57mm
• BELL 502 TX: 52mm x 27mm (2x)
