20 Changing the Backup Battery
The LR810 has a backup battery which maintains the clock and memory
when main power is off.
When the battery requires changing, the LR810 displays a “Low Battery”
message each time the unit is switched on.
When this message appears, you should install a new battery as soon as
possible.
The battery compartment is at the top of the rear of the LR810 indicator.
All totals + time/date.
WARNING - memory lost if power off and battery out for 30 seconds
