b) Buttons on screen do not function
Note:
Bear in mind that grayed out buttons on screen are deliberately inactive.
plusoptiX A12C:
Place the fingertip of your index finger flat on the screen to select a button. Do not tap on
the screen with the fingertip or finger nail.
plusoptiX A12R:
Tap on the screen with the fingertip or finger nail.
Every time you touch the screen a small mouse pointer indicates the place in which the
screen has been "hit". If you are unable to select a button by touching the screen, check the
position of the mouse pointer on the screen. Ensure that the mouse pointer hovers above
the button.
Please read chapter 4.1.14 "External mouse or keyboard" if you prefer this option.
c) Screen flickers during a measurement
If the camera lens of the device is too close to a person or an object, the integrated infrared
LEDs automatically switch off. The camera image on the screen is then not exposed and
shows up black. After a second, the devices switches on the infrared LEDs again and if the
person or object is still too close to the camera, only a short white flicker appears on the
screen before the infrared LEDs are switched off again.
Simply increase the distance between the camera lens and the person or object, and the
exposure of the camera image will automatically adjust again.
