At this point you can adjust the brightness of the integral screen to suit your
personal preference for normal use.

We recommend that brightness settings 6 and 7 should only be used when
the screen is difficult to read due to very bright ambient light.
A lower brightness setting will extend the useful life of the screen.
This menu item offers the choice between three different display operation
modes:

Always on

Temporary

Always off
Selecting 'Temporary' will switch the display is on for a short while each
time the PDT 3100 HV is being operated. Shortly after operation the display
will be switched off again automatically.
 The brightness of the display can be adjusted separately with the menu item
'Display Brightness' (see above).
In this menu item you define the language to be used for the displays on the
screen of the front panel of the PDT 3100 HV.
The PDT 3100 HV has an automatic power-down function, which will switch
off the device after 90 minutes without user operation or playback.

The menu item "Energy Saver" lets you disable the Auto-Power-Down
function in countries outside the EU.
