6.3.5 Adjusting the backlight timer
When the instrument is first switched on, the backlight goes on to illuminate the
screen. If no soft key is pressed, the backlight will remain on for the pre-set 'backlight
time', and will then go off. The timer associated with the backlight time is restarted
whenever a soft key is pressed (that is, the backlight remains on for the backlight time
after the last soft key press).
Note: The OxyDetect is factory configured for the backlight to remain on continuously
(000). Should the end user require the backlight to switch off after a timed period of
inactivity please follow the procedure as described below.
To adjust the backlight time:
1.
Select
Settings
Backlight.
2.
Change the backlight time (duration) setting as required, then press the
soft key.
