Frequently Asked Questions (FAQ):

Q: Can I submerge the lock in water?

While the lock features a water-resistant cover protecting the electronic components against rain and splashes, it should not be submerged completely under water.

Q: What happens if the thief attempts to cut the cable?

The internal wiring triggers a continuous 110dB siren instantly upon being cut, alerting everyone nearby even if no vibration occurred first.

Q: How long do the batteries last?

The included 4 × LR44 batteries provide long standby power under normal daily usage. Replacing them takes under a minute using a small screwdriver.
