WARNING
It is strictly prohibited to carry out any attempt of repairs other than by approved and
trained personnel.
Check all mounting fasteners for tightness at a regular interval.
To maintain a smooth operation, clean the device regularly. Use water, mild detergent
and a soft cloth.
Battery
Devices of type F31111 use a 3.0 V BR2330A lithium battery as the power supply for its internal
real-time clock (RTC). Under normal conditions this battery will last for a minimum of five years.
Low battery power affects the operation of the RTC, causing it to reset at every power-up. When
the battery voltage is low, a log message will appear in the product's server report.
CAUTION
Do not replace the battery yourself. Contact Axis support if the log message requests a
battery change.
Lithium coin cell 3.0 V batteries contain 1,2-dimethoxyethane; ethylene glycol dimethyl ether
(EGDME), CAS no. 110-71-4.
