If the classroom is longer than 15 meters (16.4 yards or
3.
49.22 ft), a second receiver is necessary in the middle of
the classroom for participants in the back.
Connect the optional small receiver to the original
4.
receiver with included 5m (5.46 yards or 16.4 ft) cable.
Install the small receiver from the original receiver, at
5.
the same height, same angle.
The receiver should point downwards at a 35 to 45
6.
degree angle, towards the direction from where the
student and teacher transmitters will be held.
Avoid placing the receiver directly under light, since
7.
IR transmission can be adversely effected by sunlight.
