Precautionary Measures

➠ 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, direct its signal emitter towards the indoor unit of the air conditioner when pressing the buttons. The indoor unit will confirm receipt of the signal with a short beep.

➠ Signals can be received at a distance of up to 8 meters in a straight line from the indoor unit within a 45° angle to the left and right. There must be no obstacles between the remote control and the unit that could block the signal.

➠ The remote control must be kept at a distance of at least 1 meter from television and radio equipment.

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

➠ Do not use sharp objects to press the buttons in order to avoid damaging the remote control. Do not clean the remote control with gasoline, solvents, chemically treated wipes, or similar materials.

➠ If the remote control is not functioning properly, remove the batteries, wait 30 seconds, and then reinsert them. If the functionality is not restored, 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, components, or manufacturing technology of the remote control without prior notice to the purchaser.
