  If the remote control for your Ricoh Whiteboard isn't working, check the battery orientation and replace dead batteries. Ensure you're within range and pointing the remote at the sensor window, without obstructions. Strong fluorescent lighting or direct sunlight may interfere, so adjust accordingly. Also, turn off infrared functions on nearby devices like computers or PDAs that might be causing interference.
