If you do not use the prescribed screws, make sure that the minimum isolation distance
between the electronics and non-standard fixing elements is 2 mm. Mount the panel in such a
manner that it does not resonate during the product function. Make sure that there is no gap
between the button panel and
2N

panel or seal the gap if any properly to avoid the
speaker acoustic fault and speaker – microphone acoustic feedback (see later).

LiftIP 2.0 TOC Design Installation
The TOC version is designed for lift cabin wall mounting. Fit the metal cover onto screws that are
smaller than the hole of the diameter 0.8 mm if possible. Use screws with flat surfaces alone or
cone-head screws combined with the appropriate washer. Place the device on the selected
installation site, mark the screw holes.
Off-Panel Microphone Mounting
By default, the microphone is located directly on the
2N
®
LiftIP 2.0
PCB (refer to the drawing for
location). In cable versions, the external microphone is attached to a holder with a diameter of
25 mm and self-adhesive foil, the microphone is typically connected to the appropriate
motherboard connector via a cable.
The sticker
helps you mount
the microphone behind any
button panel hole (the minimum hole diameter is 3 mm or the hole is composed of smaller holes
of the same area).
Switching to the external microphone is automatic (microphone connection is
detected).
The minimum center-to-center distance between the speaker and the
microphone is 90 mm.
A shorter distance may lead to acoustic feedback. A longer distance
does not matter.
•
Caution
Make sure that microphone hole is sealed properly to record only sounds from the
cabin instead of the noise from the shaft or space behind the panel.

Caution
If you use screws larger than recommended, the device may not be easily removed
without unscrewing the screws.

properly.
