VoiceLift System with PVS 405D Installation Guide • Introduction 3
Planning the Installation
Before you begin the installation, consider the major factors discussed in the following
sections to ensure that the installation of the VoiceLift System 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
System. Because IR technology requires line-of-sight placement, take into consideration
anything that could affect or block the transmission of the IR signal from the microphone
to the receiver (see Room Considerations on the next page).
