  If the remote control for your Sharp Speaker System isn't working correctly, start by checking if the battery polarity is correct and replace the battery if it's dead. Then, adjust the distance and angle of the remote control and remove any obstructions in front of the speaker. Also, eliminate strong light shining on the remote sensor and ensure that remote controls for other equipment are not being used simultaneously.
