3. Setup
3.1 Unpacking and Placement
Carefully remove the safe from its packaging. Due to its weight (870 lbs), professional assistance is recommended for moving and placement. Ensure the chosen location is level and provides adequate space for opening the door fully.
3.2 Battery Installation (for Electronic Lock)
The electronic lock requires a 9-volt battery. Connect a new Duracell 9V CopperTop battery to the battery connector located on the keypad. Slide the battery back into the housing and close the tray.

3.3 Anchoring the Safe
For maximum security, the safe must be anchored to a concrete surface. Four pre-drilled bolt-down holes are provided at the bottom of the safe, and mounting hardware is included. Follow local building codes and safety guidelines for proper installation.

4. Operation
4.1 Opening the Safe for the First Time
To open the safe for the first time, enter the default combination: 1-2-3-4-5-6. After entering the combination, you will hear a double beep. Turn the handle to open the door. Once the door is open, extend the bolts by turning the handle again. This prevents accidental lockout while changing the combination.
4.2 Changing the Combination
With the door open and bolts extended:
- Hold down the '0' (zero) key until you hear a double beep.
- Enter the current combination (e.g., 1-2-3-4-5-6). You will hear another double beep.
- Enter your new 6-digit combination. You will hear a double beep.
- Re-enter your new 6-digit combination to confirm. You will hear a final double beep.
Important: Test the new combination several times with the safe door open before closing it to ensure it works correctly.
4.3 Interior Organization
The safe features a fully carpeted interior with a triple gun rack, offering 40 total gun slots. It includes six adjustable medium shelves and two adjustable full-length top shelves. The interior can also be configured as an all-shelf interior by removing the gun rack components.

5. Maintenance
- Cleaning: Wipe the exterior with a soft, damp cloth. Avoid abrasive cleaners.
- Door Seal: Periodically inspect the intumescent door seal for any damage or wear. Ensure it is free from obstructions.
- Battery Replacement: Replace the 9-volt battery in the electronic lock annually, or immediately if the low battery indicator activates.
- Lock Mechanism: Do not lubricate the lock mechanism. If the lock feels stiff, contact customer support.
6. Troubleshooting
6.1 Electronic Lock Issues
- Keypad not responding: Check the 9-volt battery. Replace with a new Duracell 9V CopperTop battery if necessary.
- Incorrect combination entered: The lock will typically beep to indicate an incorrect entry. Wait a few seconds and re-enter the correct combination carefully. Multiple incorrect entries may trigger a lockout period.
- Lockout: If the lock enters a lockout mode after too many incorrect attempts, wait for the lockout period to expire (usually 5-15 minutes) before trying again.
6.2 Door Not Closing/Opening Smoothly
- Check for any obstructions around the door frame or locking bolts.
- Ensure the safe is on a level surface. Adjust if necessary.
