Using the PalmSAT Pulse Oximeter
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 180 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.
