Huawei TE30 Manual page 7

Free-Standing
Place the TE30 on a flat surface.
If you have to place the TE30 on an inclined surface, ensure that the inclination is less than 15° so
that the TE30 can function properly.
Inverted Installation
Purchase a bracket for inverted installation and mount the TE30 onto the ceiling using the bracket.
The bracket must meet the following requirements:

It is able to bear a weight of at least 10.5 kg (23.15 lb) and has a thickness between 2 mm (0.08
in.) to 3 mm (0.12 in.).

It comes with a location pillar, which can be inserted into the location hole of the TE30. The
distance between the screw hole on the bracket and location pillar must be 14.5 mm (0.57
in.), which is also the distance between the two holes on the bottom of the TE30.

It comes with a screw hole and one or more 1/4"-20UNC screws.
Note:

When attaching the purchased bracket and TE30, it is recommended that you use a 1/4"-20UNC screw
delivered with the purchased bracket rather than a 1/4"-20UNC screw delivered with the TE30 because the length
of the latter may be too long or too short to hold up the purchased bracket.

In this installation mode, the mesh enclosures of the microphones must be rotated 30 degrees in the directions
shown in the following figure until they are tightened. Do not rotate the mesh enclosures in other installation
modes; otherwise, sound pickup may be affected.
