 CAUTION
•  In case that the indication lamp (yellow) does not turn ON although the commands are sent, the commands are not received by the 
indoor unit. In such a case, send the commands again.
•  The transmitter of the controller has the vertical directivity to the receiver, and the permissible angle for transmitting is within 50º. How-
ever, 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.
 NOTE
The above gure shows the case of a 4-way cassette type indoor unit. The gures for other models are partially different.
LCD (Liquid crystal display) indication
When viewed from certain angles the LCD can be difcult to read.
The viewing angle ranges from an optimal of 60º down to 30º, as shown in the diagram on the right.
If the viewing angle is below 30º, the indications not displayed are slightly faded so that makes the indication be hardly 
readable. It is the characteristics of this LCD, which is not abnormality.
