  If the remote control for your BenQ Digital Signage isn't working, consider these possible solutions: * Ensure the remote control function isn't locked; unlock it if it is. * Verify the batteries are correctly oriented and not dead; replace them if needed. * Make sure you're within range and at the correct angle to the display. * Confirm the remote is pointed directly at the display's sensor window, with no obstructions. * Check for strong fluorescent lighting or direct sunlight affecting the sensor. * Look for nearby devices emitting infrared signals that could cause interference; turn off their infrared function.
