For added safety when removing the ceiling tile at a later time, securely attach the electronics enclosure to the
ceiling supports using suitable wire or other hardware appropriate for your ceiling type and in accordance with
local regulations. Be sure that the length of wire you use to secure the electronics enclosure is short enough to
prevent the enclosure from striking the person removing the ceiling tile.

For Polycom TPX HD 306M Systems, you must
position the two Ceiling Microphone Arrays
relative to the multipurpose table. Therefore,
before installing the first Ceiling Microphone
Array, you must use the measurements at the
right to determine the placement of the creden-
za and the multipurpose table in your room.
When determining the placement of the Ceiling
Microphone Arrays, you must ensure that:
The left Ceiling Microphone Array will be 2 ft
(61 cm) to 3 ft (91 cm) to the left of the
vertical centerline of the multipurpose table,
and will be no more than 6 in (15 cm) from
the horizontal centerline of the multipurpose
table.
The right Ceiling Microphone Array will be 2
ft (61 cm) to 3 ft (91 cm) to the right of the
vertical centerline of the multipurpose table,
and will be no more than 6 inches (15 cm)
from the horizontal centerline of the multi-
purpose table.
