1.4 Position planning of the digital infrared receiver

1.4.1 Position away from lighting equipment

Although classroom audio system has good
anti-interference performance to ambient light, the
distance of the receiver from lighting equipment must be
at least 50 cm to guarantee adequate intensity and
stability of infrared signals.
Figure 1.3 Digital infrared receiver position (near lighting
equipment)
Note:
 If the position of lighting equipment is higher
than the position of the receiver, the disturbance
can be ignored.

1.4.2 Avoid direct intense light

Exposing the receiver to intense light source may
cause system failure or noise. Please do not mount the
receiver in such a way the intense light source
irradiates directly, as shown in follow figure:
