Optoma UHD38 Projector Remote Control Troubleshooting

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.
