• 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.

batteries will require replacement in about 6 weeks.
