be set permanently off, permanently on; or may be set to remain on for a preset time interval after which the backlight extinguishes. Pressing any
button re-starts the backlight time interval. this interval may be set from 5 seconds to 60 seconds in 5 second increments. It should be noted that the
instrument consumes more power when the backlight is illuminated.
under normal ambient lighting conditions, there should be no need to use the backlight.
If the backlight is not required, set the Backlight timeout permanently to oFF to ensure maximum battery life. By default, the Backlight timeout is set
to 15 seconds.
