Precautions

➠ Before using the remote control for the first time, insert the batteries and make sure that the “+” and “-” contacts are correctly aligned.

➠ Make sure the remote control is pointed towards the signal receiver, with no obstacles in between, and that the maximum operating distance of 8 meters is observed.

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

➠ If the remote control does not operate properly, remove the batteries for 30 seconds before reinstalling them. If the issue persists, replace the batteries.

➠ When replacing the batteries, do not mix new batteries with old ones, or batteries of different types, as this may cause remote control malfunction.

➠ If the remote control has not been used for a long period, remove the batteries to prevent leakage, which may damage the remote control.

➠ Dispose of used batteries properly.

Additional warnings:

This appliance is not intended for use by small children or infirm persons without supervision. Small children should be supervised to ensure that they do not play with the appliance.

Note

1. This remote control is universal and includes all functional buttons. Please note that some of them may be inactive depending on the specifications of your air conditioner. If certain functions are not supported by your air conditioner, the corresponding buttons on the remote control will simply not work.

2. In cooling mode, the HEAT and ELE.H buttons are inactive and therefore will not function.

Signal transmission process

Pressing any button on the remote control initiates the transmission of a signal to the indoor unit of the air conditioner. Upon receiving a new command from the remote control, the air conditioner sends a signal back. If the signal is successfully sent and confirmation is received, a sound signal is emitted to confirm the new command.
