About batteries
• When replacing the batteries, use batteries of the same type, and replace the two old batteries
together.
• When the system is not used for a long time, take the batteries out.
• We recommend replacing once a year, although if the remote controller display begins to fade or if
reception deteriorates, please replace with new alkali batteries. Using manganese batteries reduces
the lifespan.
• The attached batteries are provided for the initial use of the system.
The usable period of the batteries may be short depending on the manufactured date of the air
conditioner.
