Larson Davis System 824 User Manual

11/8/00 Front Panel Keys; their Functions and Menus 3-5
Check menus allow you easy access
to system or instrument settings.
The
u
or
d arrow keys, allow
you to select the desired menu item
and by pressing the
r key you can
make changes to the setting.
The settings menu allows you to adjust the contrast (or view-
ing angle), turn the backlight on or off, and adjust settings
that control the power-conservation features. These power-
conservation features allow you to set the instrument to do
the following:
• Turn the backlight off after a set amount of time
• Automatically go into a standby mode after a set amount
of time (display blanks and serial port turns off)
• Automatically shut off the instrument after a set amount
of time
• Conserve internal battery for memory retention
If no keyboard activity is detected for the period of time set
by the
Backlight Time
setting, the instrument will turn off
the backlight. This conserves battery life since the backlight
is a major consumer of battery power. If
Backlight Time
is
set to zero (0), then the timer is disabled and the backlight
will stay on until turned off manually. If the battery capacity
is less than 30%, the backlight will automatically shut off in
3 seconds to conserve power. If the battery capacity is less
than 15%, the backlight will not turn on at all.
