•
“Battery Life” is the number of hours before battery failure when
the unit is left on (5 minutes of a processing operation and 55 minutes
of continuous display only (no processing operation) per hour in the
Contacts Mode, plus the backlight operation described below). The
above values assume ambient temperature of 20
°
C, starting with a
fresh set of new batteries.
•
“Backlight Operation” is the number of minutes the backlight is
turned on per hour during the display only (no processing operation)
period.
•
Be sure to use alkaline batteries. Manganese batteries provide very
short battery life.
