Commend WS 311V CM DA Manual page 2

Recommended mounting height of the induction loop
With a mounting height of approx. 1,100 mm (43 in), AFIL signals are ideally transmitted for children,
wheelchair users and standing adults. A distance of approx. 500 mm (20 in; arm's length) is recom-
mended between the Intercom station and the inductive hearing aid. If required, adjust the mounting
height to the respective requirements and local regulations.

Recommended mounting height of operating elements
For barrier-free operation, operating elements should be mounted with enough space to walls and
corners. Operating elements such as call buttons should be installed between 800 mm and 1,000 mm
