6. Troubleshooting
6.1 Difficulty Opening the Lock Box
- Incorrect Combination: Double-check that the correct 4-digit combination is entered and that each number is precisely aligned in the center of the dial window.
- Stuck Dials: If dials are stiff, gently wiggle them while attempting to enter the combination. Ensure no debris is obstructing the dials.
- Reset Lever Position: Verify that the internal reset lever is fully in the 'B' (locked) position after setting the combination. If it was accidentally left in the 'A' (reset) position, the combination may have been inadvertently changed.
