➠ Make sure that the remote control is directed towards the receiver without any obstacles, and that the maximum distance is 8 meters.

➠ Do not drop or throw the remote control. Prevent any liquid from entering the remote control. Do not expose the remote control to direct sunlight or excessive heat.

➠ If the remote control does not function properly, remove the batteries for 30 seconds before reinstalling them. If it still does not work, replace the batteries.

Signal Transmission Process

Pressing any button on the remote control initiates the process of sending a signal to the indoor air conditioning unit.

If the signal is sent successfully and confirmation is received, an audible signal is emitted to confirm the new command.
