Important Notes about Battery Use
Four AA alkaline batteries provide the device with approximately 80 hours
of continuous operation, while the Rechargeable NiMH Battery Pack
provides approximately 40 hours of continuous operation.
Clock/calendar settings can significantly affect battery storage life.
Batteries drain during storage, but they drain much more quickly when the
unit’s clock/calendar functions are set. Refer to “Clock and Calendar
Settings” for more information.
With AA Batteries
If the clock/calendar is not set when the unit is stored, alkaline batteries
will need replacement in 10-12 months if the unit has not been used.
If the clock/calendar is set when the unit is stored and if the unit has not
been used, alkaline batteries will require replacement in about 6
weeks.
Using the oximeter will shorten the required replacement time.
With Rechargeable NiMH Battery Pack
If the clock/calendar is not set when the unit is stored, and if the unit
has not been used, the Rechargeable NiMH Battery Pack will need
recharging at least every 2 months.
If the clock/calendar is set when the unit is stored, and if the unit has
not been used, the Rechargeable NiMH Battery Pack will need
recharging at least every 3 weeks.
Using the oximeter will shorten the required recharging time.
Recharging Batteries (NiMH Battery Pack only)
Completely recharging the NiMH battery pack requires approximately
90 minutes when the unit is completely discharged.
The expected useful life of the Rechargeable NiMH battery pack is 500
charge/discharge cycles, or approximately 10 years, whichever is first.
The battery pack must be charged at least once each year to maintain
optimal battery life.
AA alkaline batteries cannot be recharged in the charging stand.
