Humanware explore 8 User Manual page 26

Screen is black:
If the unit is laying on a table or any flat
surface, the image may be black. Lift your
magnifier to see whether this is the reason
why your screen is black.
If this does not solve the problem, try restarting
your device.
Image is out of focus in magnifier:
Make sure Autofocus is set to Unlocked in the
menu. Move the device back and forth over
the document you are viewing. This will make
explorē 8 re-focus on the document.
explorē 8 shuts down after inactivity:
This is a normal behaviour intended to
preserve the battery. By default, explorē 8 will
shut down after 5 minutes of inactivity. It is
possible to configure the default auto-off timer
to 1 minute, 2 minutes, 5 minutes or 10
minutes.
