14.2 Troubleshooting

1. The monitor does not work
Check whether the power cable is connected to the power socket and whether it is
switched on. Check also whether the monitor is connected and is switched on.
2. The message "Boot error" appears on the monitor after switching on the plusoptiX R09
The plusoptiX R09 does not boot completely. Switch off again the plusoptiX R09 at
the on/off switch. Check whether there is a flash drive inserted the USB connector. A
connected USB flash drive is likely to disturb booting the device properly.
3. The measurement routines cannot be chosen
Make sure the USB Stick with the measurement routines is plugged in. And the files are
correctly programmed. Make sure the file names have no spaces.
4. If you do not like qemacs:
To create your measurement routines you can use any Text editor you like, but
sometimes the text editor puts in a view signs automatically (like Linefeeds, Carriage
returns...). So this can lead to trouble with the measurement routines.
One or both pupils are larger than 8.00 mm. Increase the lighting in the room to
contract the pupils.
One or both pupils are smaller than 4.00 mm. Decrease the lighting in the room to
dilate the pupils.
Infrared component in ambient light is too strong. Avoid direct sunlight and
switch off "warm" light sources such as halogen or incandescent lamps.
If the measured Value is ≥ +5.00 dpt or the measured Value is ≥ -7.00 dpt this
status message will appear.
