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.
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.
CAUTION:
Remove the batteries if the device will be stored for more than 1 month.
