7. INSTALLATION PRECAUTIONS
Because the infrared wireless microphone and the IR-820SP have their own directivity for infrared transmission
and reception, take care that they are installed and operated under stable communication conditions.
7.1. Installation Position
• Install the IR-820SP in the ceiling in the center of the room whose size should not exceed 10 m x 10 m (30
ft x 30 ft) with ceiling height of 2.5 – 3 m (8.2 – 9.84 ft) so that the Infrared wireless microphone can be used
everywhere throughout the room.
• The infrared beam can be blocked by a human body or other objects. To avoid this, install the IR-820SP in
the way that it can be viewed from the infrared wireless microphone.
Note
In the figure at right, the microphone directly facing
the IR-820SP can be used because no obstacle
exists between them.
However, when a talker turns his or her back on the
IR-820SP, signal reception from the microphone
is interrupted because the human body acts as
obstacle.
7.2. Distance Between the Infrared Wireless Microphone and IR-820SP
Malfunctions or noise could result from the infrared wireless microphone and the IR-820SP being too close to
each other. Keep the infrared wireless microphone at least 2 m (6.56 ft) away from the IR-820SP.
