Installation Procedures
Determine Coverage Area
When using the »PRO IR-202« transmitter in single-channel mode with the
PR 22+ receiver, the system coverage area will exceed 186 m². »PRO IR-
202« units automatically adjust to give the best coverage area possible in
both 1-channel and 2-channel modes.
Figure 1 illustrates the typical coverage pattern for the »PRO IR-202« This
can be affected by direct/indirect sunlight, reflections on walls and room
construction.
Reflections of the infrared light from walls, ceilings, and floors may change
these patterns.
Important: Remember to point the transmitter towards the listening audi-
ence.
Remember: Most objects block infrared light. The transmitter cannot be
concealed behind walls, glass, curtains, etc. These patterns are the di-
rect radiation pattern. The infrared radiation does not drop to zero outside
the illustrated patterns; it decreases. It still may be useable at a greater
distance, depending on the receiver sensitivity and the reflective charac-
teristics of the room.
The »PRO IR-202« can be operated with or without the faceplate, if de-
sired. The faceplate can be removed and painted to match the room de-
cor. Lightly sand the face-plate with 400 grit sandpaper, apply primer and
two coats of the desired final color.
Do not paint the infrared lens behind the faceplate of the »PRO IR-
202«!
