Power saving
Auto power down
The instrument will automatically power down after five minutes of
no interaction with the unit. Ten seconds before it is about to shut
down the instrument will alert the user with a series of beeps. If
there is still no interaction with the instrument it will start the auto
power down routine and shut down.
Brightness modes
The unit will power up in “indoor mode”. In “indoor mode” the
screen is set to be bright enough to use in most environments. If
the user is in a very bright environment and they are having
difficulty seeing the screen, they have the ability to turn the
brightness up to high brightness. They can do this by pressing and
holding the up navigation button in the main menu screen for three
seconds.
Turning the screen up to high brightness will increase the drain on
the batteries and reduce the maximum number of tests that can be
carried out.
The instrument cannot be turned back to “indoor mode” once it is
in high brightness mode, but will always power up in indoor mode.
Screen dimming
If there is no interaction with the instrument in all operational
modes for 15 seconds the screen will dim and turn the backlight off.
