4.4 DISPLAY ILLUMINATION

The I/O (on/off) switch also turns on the backlight that lights up the display.
When any switch is operated or there is any other activity, such as connecting a
probe, the backlight will turn on. It will turn off again after a short time to save
battery power. Activate the I/O switch (for about half a second) to turn on the
backlight without causing any other action.
If there is very little charge in the battery then the backlight will not turn on. This
saves unnecessary battery drain.

4.5 SWITCH FUNCTIONS AND ICONS

The I/O (on/off) switch always keeps the same function but for the other three
switches the display will show a small "icon" to indicate the function of each
switch. The icon is in the same corner as the switch it relates to. The switch icon
becomes inverted (black for white) when the switch is operated. If a switch has
no icon then it has no function at that time.

4.6 AUTO POWER ON

The instrument will automatically switch on when it is connected to a Redpost
printer/charger or a Redpost battery charger. This allows the battery charging to
be controlled and the charging information to be displayed.
The I/O (on/off) switch will not turn the instrument off while it is connected to a
charger but it can still be used to turn on the display backlight.

4.7 AUTO POWER OFF

The instrument uses several methods to reduce battery power consumption. The
automatic control of the display backlight is described above.
If the instrument is idle and waiting to record a file it will automatically switch off
after ten minutes. The instrument is idle if no switches are activated, no data
communication is taking place and it is not connected to an active battery
charger.
If the instrument is idle and displaying the results of a recorded file it will
automatically switch off after twenty minutes.
When the instrument switches off automatically any recorded files are saved.
To resume normal operation activate the I/O (on/off) switch or connect the
instrument to a Redpost battery charger.
