Locations to avoid:
• Places where line of sight could be obstructed; e.g., too close to the
projector
• Corners of the room
• On walls, at less than 6' or more than 12' up from the base
• Areas that receive direct sunlight
• Need for optional VLR 102 SR secondary receiver
One or more secondary receivers (VLR 102 SR) may be needed if:

The room is larger than 40' by 40'.

Obstructions exist between the microphone and the receiver.

The room is odd-shaped, e.g., L-shaped or long.

The room has recessed or sheltered areas, such as alcoves or bays.

The room has large windows or windows on multiple walls.

Portions of the walls are dark and/or covered. Dark surfaces reduce
signal reflection.
