3.4 Position planning
3.4.1 Precautions in planning the digital infrared
transceiver/receiver
Due to strict demands on intensity and stability of
infrared signals in an infrared wireless conference
system, please read section 1.4 carefully and take all
aspects of infrared signal transmission into consideration
before planning the mounting position.
3.4.1.1 Avoid direct sunshine
Exposing the transceiver/receiver to sunshine or an
infrared illuminant may cause system failure or noise. To
guarantee adequate intensity and stability of infrared
signals avoid mounting the transceiver/receiver near to
an infrared illuminant, as shown in the following figure:
Figure 3.4 Digital infrared transceiver/receiver position
(near window)
Cover the window with a curtain to protect the
transceiver/receiver from direct solar radiation;
The distance between the transceiver/receiver and
the window nearby must be more than 2 meters.
3.4.1.2 Stay away from lighting equipment
Although HCS-5300 system has good anti-interference
performance to ambient light, the distance of the
transceiver/receiver from lighting equipment must be at
least 50 cm to guarantee adequate intensity and stability
of infrared signals.

(near lighting equipment)
3.4.1.3 Stay away from wall, pillar and other
obstacle
Because objects in a meeting room may cause infrared
light reflection (see section
1.4.2
), the transceiver
/receiver should not be mounted near to a wall, pillar or
other obstacle; otherwise, the transceiver/receiver could
feature malfunctions by detecting the reflected own
infrared signals.
The distance of the transceiver/receiver to the obstacle
should be at least 30 cm.
Figure 3.6 Reflected infrared light received by the
transceiver/receiver
Note:
A distance of 30 cm will be adequate to make
the transceiver/receiver unaffected. However, if
highly reflective surfaces exist in the meeting
room, e.g. mirror, the disturbance still exists.
Especially reflections caused by pillars in large
halls may cause disturbance.
Note:
If the position of lighting equipment is higher
than the position of the transceiver/receiver, its
disturbance can be ignored.
