Mounting
Just drill holes into the lift cabin wall as indicated in the drawing below or as printed
1:1 on the audio unit package. The larger hole is intended for cable passage. Round
the hole edges to avoid cable damage!
Note: The two 2.5 mm large holes in the window area are used where the mounting
panel rear is inaccessible. The 2.5 mm diameter is suitable for all wall mounting
options using plywood, chipboard, laminated plastic etc. with the aid of the screws
included. For front metal panel wall mounting drill M4 threaded holes.
Further steps can only be made after connection and are thus included in the next
section.
