The general day-to-day usage of your Tympa may occasionally cause the camera to be off-centre. You are able to re-centre the image so you don't have crescent views or half-moon views.
To re-centre the image please follow these steps:
- During the examination touch gently the camera
- With your finger still gently pressing, drag the camera view around to re-centre the image
Sometimes it also helps to gently adjust the handle in the part where is connects to the tray that holds the device.
