Before You Begin — Planning the Installation
Before starting installation, you must consider several major factors to ensure that the installation of the VoiceLift
Microphone is as smooth and trouble free as possible, and that the result meets the needs of the users. Placement
of the receiver (sensor location) is very important for optimal performance of the VoiceLift Microphone. 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.
The lists on the following pages, though not comprehensive, should be consulted to help ensure that key aspects
have been considered.

Due to the operating frequencies of the microphone and receiver, lighting fixtures such as fluorescent lights and
plasma displays should not affect performance of the system.
