Cautions on remote controller installation:

Don t  throw the remote controller or give it big impact.
The remote controller should be in the reception range, and the transmittal part should point
to the orientation of indoor unit receptor.
Before installation, operate the remote controller to determine its location in a reception range.
Keep the remote controller at least 1m apart from the nearest TV set or stereo equipment. (It
is necessary to prevent image disturbances or noise interferences.)
Do not install the remote controller in a place exposed to direct sunlight or close to a heating 
source, such as a stove.
Note that the positive and negative poles are right positions when loading batteries.
