1.9 REPLACEMENT OF THE LOCK BATTERY
Caution. Risk of explosion in the event of replacing the battery with
an incorrect type. Dispose of used batteries according to the
instructions.
Ojmar locks automatically detect low battery levels. When this occurs, the yellow
LED flashes 3 times for each opening or closure cycle performed.
Up to 9 opening and closure cycles are possible as of the time when the low battery
is detected. On the tenth cycle, the lock can only be opened (never closed). This
prevents the lock battery from being used up and the lock from being blocked.
Follow the steps below to replace the batteries:
1. Remove the torx screw.
2. Open the battery cover.
3. Remove the battery holder.
4. Replace the four AA batteries (two on each side of the support).
5. Insert the battery holder.
 NOTE: The cover should fit easily. To do so, first insert the wire and then the
battery holder.
6. Fit the cover and tighten the torx screw.
