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.
