The infrared (IR) module is a small box or dongle that sends remote signals to a screen or projector, to change optotypes via the SiVIEW app. It works just like a regular remote control.

• Make sure the IR dongle hasn’t fallen and is properly pointed toward the screen or mirror.

• Check that there is no dirt or obstruction in front of the screen’s or projector’s IR sensor.

👉 Once these checks are done, if the screen still doesn’t respond, move on to the next step.

1. Point the IR dongle at the screen or projector

2. Send a command (via SiVIEW)

3. Observe if the screen reacts (optotypes change)

➡️ If the screen does not respond:

• Test the screen/projector’s remote control:

  • If the remote works but the IR dongle doesn’t, the module may be faulty.

• Open your phone’s camera app

• Point the camera at the IR area of the module (the smooth surface)

• Send a command via SiVIEW
  👉 If you see a blinking light on your phone’s screen, the IR module is working.

That doesn’t necessarily mean the module is faulty. Some smartphones (especially recent iPhones or high-end Android devices) filter infrared light, particularly on the rear camera. Try the following:

• Use the front-facing camera, which usually has less filtering

• Try with a different smartphone

If, after all these steps, you see no blinking light and the screen doesn’t respond:
➡️ Please contact our support team. Your IR module is likely defective.
