1Consider replacing the batteries if it has been a long time since they were last replaced.
If the battery compartment or the contact has rust or any foreign material, remove it. Insert the battery with the positive/negative poles properly aligned.
2Having any active three-wavelength lamps near the remote control may lead to a malfunction due to frequency interference.
Try using your remote control with the lamp turned off. If it works well, the lamp is the problem.
