Locking: Press the lock cylinder to engage - you'll hear a single "DU" sound indicating alarm activation. After 5 seconds, the system becomes vibration-sensitive.
Alarm Activation: When vibration is detected, the lock emits three "DU DU DU" sounds. Subsequent vibrations trigger continuous 10-second alarm cycles.
Unlocking: Use the provided key to open the lock - the alarm stops immediately. The 5-second grace period allows authorized access.
Replace batteries when you hear continuous "Ge,Ge,Ge" sounds or alarms lasting less than 10 seconds. Use the included spanner to remove the four screws, replace the battery observing proper polarity (+/-), and reassemble.
