The transmitter of the controller has the vertical directivity to the
receiver, and the permissible angle for transmitting is within 50º.
However, the capable distance for transmitting gets half when
the transmitting angle is 50º, and also get shorter in case that an
electronic type light is used in the room.

When viewed from certain angles the LCD can be difficult to
read.
The viewing angle ranges from an optimal of 60º down to 30º,
as shown in the diagram.
If the viewing angle is below 30º, the indications not displayed
are slightly faded so that makes the indication be hardly

INSTALLED SIDE BY SIDE OPERATION
This function is used when operating several receivers or indoor
units side by side, to prevent a malfunction because of receiving
incorrect signals from the wireless remote controllers used in
other areas.
Only the communication between the paired setting is possible,
and 4 pairs (A, B, C, D) are available.
For example, the receiver set as "A" can only receive signals
from the wireless controller set as "A". It cannot receive signals
from wireless controller set as B, C or D.
Refer to the installation & maintenance manual or the operation
manual for each receiver kit or indoor unit settings. Depending
on the type of the receiver kit or the indoor unit, only setting as
