Safety Precautions

➠ The remote control is not a toy. Do not allow children to play with it and do not play with it yourself.

➠ When using the remote control, point its signal emitter at the indoor unit of the air conditioner when pressing buttons. The indoor unit will confirm signal reception with a short beep.

➠ Signals can be received up to 8 meters away in a straight line from the indoor unit at an angle of 45° to the left and right. There should be no obstacles between the remote control and the unit for proper signal transmission.

➠ The remote control should be kept at least 1 meter away from television and radio equipment.

➠ Do not drop the remote control or subject it to strong impacts. Protect it from direct sunlight, heat sources, water, and high humidity.

➠ Do not use sharp objects to press the buttons to avoid damage. Do not clean the remote with gasoline, solvent, chemically treated wipes, etc.

➠ If the remote control does not function properly, remove the batteries, wait 30 seconds, and then reinsert them. If the problem persists, replace the batteries.

❗👉➨ Remove the batteries from the remote control if it will not be used for an extended period.

❗👉➨ Attention The manufacturer reserves the right to make changes to the design, configuration, or manufacturing technology of the remote control without prior notice to the customer.
