Important Notes about Battery Use
• To conserve battery life, Nonin recommends disconnecting the CO
2
sensor from the 9847 when CO
2
detection is not in use. The flashing lamp in the CO
2
sensor consumes a significant amount of energy.
• Setting the month to “
00
” disables the calendar and clock functions and helps conserve battery life.
Refer to “Calendar Settings” on page 20 for additional information.
• The memory of the 9847 may be erased when the batteries are removed.
• Replacing batteries may erase the clock settings of the 9847.
• Six AA alkaline batteries provide the device with approximately 90 hours of continuous operation.
•
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. Refer to “Calendar Settings” and
“Clock Setting” (starting on page 19) 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.
