Using the 8500 Pulse Oximeter
When batteries are critically low, the digital displays will go blank, and the Pulse Quality display will
blink amber or red, but not green. After 10 minutes at critically low battery capacity, the pulse oximeter
will shut off automatically.
.
WARNING: The device turns off after approximately 10 minutes when at critically low
battery capacity.
CAUTION: Replace the batteries as soon as possible after a low battery indication.

Always replace the batteries with fully charged batteries. Do not use fully charged
and partially charged batteries at the same time. This may cause the batteries to leak.

Important Notes about Battery Use

• Six AA alkaline batteries provide the device with approximately 100 hours of continuous operation.
• Display brightness can affect battery life; the lower settings will conserve battery life.
• Clock/calendar settings can 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.
• 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.
