Optoma UHD38 projector is equipped with an IR remote control. If your remote control doesn’t work, you can try the following tips for troubleshooting.
- Make sure that there are no obstacles between the remote control and the IR sensor on the projector that might obstruct the infra-red beam.
- Make sure the IR transmitter of the remote control is not being shined by sunlight or fluorescent lamps directly.
- Please keep the remote controller away from fluorescent lamps for over 2 meters or the remote controller might become malfunction.
- If the remote control is close to Inverter-Type fluorescent lamps, it might become ineffective from time to time.
- If the remote control and Optoma UHD38 projector are within a very short distance, the remote control might become ineffective.
- When you point the remote control to the screen, the effective distance is less than 7 meters (about 22 feet) from the remote control to the screen and reflecting the IR beams back to the projector. However, the effective range might change according to screens.
