General precautions
WARNING
• Do not use the remote controller where pacemaker users may be around. If used, turn off its Bluetooth.
- Bluetooth may cause pacemakers to malfunction and leads to an accident.
• Do not use the remote controller near electrical medical devices. If used, turn off its Bluetooth.
- Bluetooth may cause these devices to malfunction and leads to an accident.
• Do not use the remote controller near automatic doors, fire alarms, or other automatically controlled devices. If
used, turn off its Bluetooth.
- Bluetooth may cause these devices to malfunction and leads to an accident.
CAUTION
• The remote controller is permitted for use only in the country where it was purchased.
• The remote controller uses signals in the 2.4 GHz band.
- Signals in the 2.4 GHz band are used by medical devices, other similar devices, and non-licensed amateur
radio stations (hereafter referred to as other radio stations).
1. Before using the remote controller, make sure there are no other radio stations in the vicinity.
2. If a radio interference occurs between the remote controller and other radio stations, move the remote
controller or stop using the remote controller (turn off Bluetooth).
3. If problems with radio interference occur, consult the dealer from which the remote controller was purchased.
• Keep an appropriate distance between the remote controller and radio-emitting devices, such as cordless phones,
microwave ovens, and wireless LANs, to prevent Bluetooth interference from these devices that can affect normal
operation and performance of the remote controller.
• The following actions may be punishable by law.
- Disassembling or alteration of the remote controller
- Removal of certification labels
• The maximum line-of-sight distance of the remote controller is 10 meters. This distance will be shorter when
obstacles or people are in the path of radio waves or radio interference from appliances (e.g., microwave ovens)
exists.

Precautions for using smartphone application
• When operating an air conditioner from a remote controller located outside the visibility of the air conditioner,
make sure that the operation of the air conditioner will not negatively affect its surroundings or the occupants
beforehand.
• When occupants include children, elderly people, people with ailments, or people with disabilities, make sure the
remote controller is used in the presence of a capable, supervising adult.
• When one or more people are in a room with an air conditioner, let them know beforehand that the air conditioner
is going to be operated from a remote controller located outside the visibility of the air conditioner.
• Children must be supervised to stay away from the remote controller.
• Poor radio-wave conditions due to an existence of obstacles or radio-emitting devices, such as a microwave oven,
in the vicinity of the remote controller can lead to a non-response error. Periodically check the operating
conditions of the remote controller.
• The maximum line-of-sight distance of the remote controller is 10 meters. Obstacles in the path of radio waves
can shorten this distance. If a problem occurs, remove the obstacles or shorten the distance between the remote
controller and the connected device.
