Operating Instructions
Opening and Closing the Safe
- To open the safe, dial your set three-number combination on the wheels.
- Turn the lock knob to the horizontal (open) position. The lid will release.
- To close the safe, ensure the lid is properly aligned and press down firmly until it latches.
- Scramble the combination wheels to secure the safe.
Using the Security Cable
The NanoVault is supplied with a 1500 lb test security cable for added security. This cable allows you to tether the safe to a fixed object, preventing easy removal.
- Loop the security cable around a secure, fixed object (e.g., a car seat frame, desk leg).
- Feed the cable's looped end through the slot on the side of the NanoVault.
- Close and lock the safe. When the cable is wrapped around a fixed object and slid over the lock receiver inside the security box, both the NanoVault and its contents will be securely attached.
