1. The remote control cannot add functions to the device. For example, if an air conditioner does not have a fan direction function, the fan direction button on the remote control will not work.
2. The remote control is a low-power product. Under normal circumstances, the battery life is 6-12 months. Improper use will shorten the battery life. Replace both batteries at once. Do not mix old and new batteries or batteries of different types.
3. Ensure that the appliance receiver is working properly for the remote control to function effectively.
4. If battery leakage occurs, clean the battery compartment thoroughly before replacing the batteries. To prevent leakage, remove the batteries when not in use for extended periods.
