2. Low battery charge warning level
The disc lock signals low battery charge warning level with
a particular sound signal (2 consecutive and long lasting
"beeps") either during disc lock locking or electronic
activation. It is therefore recommended to replace
batteries.
WITH THE DISC LOCK OPEN (cylinder completely out), to
replace batteries:
Unscrew the two screws which join the disc lock top and
bottom parts together;
Open the two parts of the disc lock paying attention not to
cut the wires linking them together;
Replace old batteries with 2 new ones (12V type MN21).
Close the disc lock again, paying attention not to crush
the wires.
