Assembly
Bore-holes on the reverse side for attachment of the assembly panels.
Wall mounting by means of assembly plate.
If the device is intended for outdoor use, we recommend permanently protecting the
membrane keypad against UV radiation and using a suitable enclosure or at least the erection
of a sufficiently dimensioned canopy as a protection measure against constant rain or snow.
