Introduction
When batteries are critically low, the digital displays go blank, and the Pulse Quality indicator blinks
yellow or red, but not green.
Important Notes about Battery Use
• To conserve battery life, Nonin recommends disconnecting the CO
2
sensor from the 9847V when
CO
2
detection is not in use. The flashing lamp in the CO
2
sensor consumes a significant amount
of energy.
• Six alkaline batteries provide the following number of hours of continuous operation:
• Pulse oximeter only - 90 hours
• CO
2
sensor only - 24 hours
• Pulse oximeter and CO
2
sensor - 20 hours
• The memory of the 9847V may be erased when the batteries are removed.
• Replacing batteries may erase the clock settings of the 9847V.
• Calendar/clock settings can affect battery storage life. Batteries drain during storage, but they
drain more quickly when the unit’s calendar/clock functions are set. Setting the month to “
00
”
disables the calendar and clock functions and helps conserve battery life. Refer to “Calendar
Settings” and “Clock Settings” (page 23) for more information.
• If the calendar/clock 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 calendar/clock is set when the unit is stored and if the unit has not been used, alkaline
batteries will require replacement in about 6 weeks
.
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.
CAUTION:
Remove the batteries if the device will be stored for more than 1 month.
