General Description
Installing and Using the Batteries
9847 is powered by six AA size alkaline batteries. Approximate battery capacity:
• Pulse Oximeter (SpO
2
) only: 90 hours
• CO
2
and Pulse Oximeter: 20 hours.
• CO
2
only: 24 hours.
Low battery indicator illuminates when the battery capacity is low. The batteries should be
replaced as soon as possible.
Critical battery capacity is indicated by:
• low battery indicator blinks
• medium priority (equipment) alarm
To avoid loss of monitoring, batteries must be replaced immediately.
NOTE:
Audible high priority patient alarms override medium priority alarms.
If the batteries are critically low when the device is turned on, setup mode will be disabled and the
displays will be blank. Replace the batteries before continuing.
NOTE:
To conserve battery life disconnect the CO
2
sensor not in use.
NOTE:
Setting the month to “
00
” disables the calender and clock functions and helps conserve
battery life. Refer to “Calender Settings” on page 20 for additional information.
Replacing Batteries
1. Slide open and remove the battery door on the bottom of the device.
2. Remove
all six
batteries.
3. Replace all six batteries with new AA size batteries as illustrated below with the proper battery
orientation noted on the back of the device.
CAUTION:
Use only Nonin-specified battery types with this device.
WARNING: Before changing the batteries, make sure the device is off and the sensor
is not attached to a digit.
CAUTION:
The device is not designed to retain data in memory once the batteries
are removed. Memory will clear 60 seconds after removing the batteries. Replacing
the batteries before 60 seconds have elapsed most likely will result in corrupt data.
Always replace the batteries with fully charged batteries. Do not use fully charged
and partially charged batteries at the same time as this may cause batteries to leak.
