Installing and Mounting the Receiver

PRELIMINARY

This section provides an overview of the procedures for planning and performing

an installation of the VoiceLift VLR 102 Receiver and/or the VLR 102 SR Secondary

Receiver. For the complete procedures, refer to the VoiceLift Microphone Installation

Guide, part #68-1629-01.

Planning the Installation

Before you start to install the VLR 102 receiver, there are several major factors that

you must consider in order to ensure that the installation is as smooth and trouble

free as possible, and that the result meets the needs of the users.

Placeent of the receiver

Placement of the receiver (sensor location) is very important for optimal

performance of the microphone. The best location is in the ceiling, at or near the

middle of the room, where the receiver is in line of sight, regardless of the teacher/

presenter’s position in the room. This also minimizes the transmission distance.

If mounting on the ceiling is not possible, the receiver should be placed high and

centered on the longest wall of the room.

Roo layout and content considerations

Because IR technology requires line-of-sight placement, take into consideration

anything that could impact or block the transmission of the IR signal from the

microphone to the receiver. If obstruction is unavoidable, the IR signals can

bounce off walls and still reach the sensor; however, light-absorbing surfaces such

as dark walls or chalkboards also can impede the signal.

The diagram below shows a typical classroom installation incorporating the

VoiceLift Microphone.
