Infrared Influencing Elements
SENSITIVITY OF THE RECEIVER
The positioning of the receiver relative to the radiator(s) has an effect on how efficiently you will receive a
signal. For maximum sensitivity aim the back side of the receiver (the side with the clip) directly towards the
radiator. When you tilt the receiver this will reduce the sensitivity of the receiver. The receiver has a 270°
wide reception angle .

AMBIENT LIGHTING
Ambient lighting can disturb the distribution of the infrared signal. For this reason the Lingua IR system
should not be used in outdoor conditions or in rooms with very bright lightning.
