Before You Begin — 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.

Receiver Coverage

The VoiceLift receiver has the same room coverage pattern whether it is mounted on
the ceiling or a wall.

VoiceLift Connections and Signal Path
The length of each cable in the system should be between 5 feet (1.5 m)
and 100 feet (30 m). The total cable length in the system should not
exceed 300 feet (91.4 m). Cables to secondary receivers must be shielded.

VoiceLift Receiver Coverage
Coverage is dependent mainly on the room environment, but also on the
microphone. You can attain maximum coverage when the batteries are
fully charged. Reception may decrease as the battery drains, but this may
not be noticeable, depending on the environment.
