3. Setup
3.1 Unpacking and Initial Inspection
- Carefully remove the safe from its packaging.
- Inspect the safe for any signs of damage during transit. If damage is found, contact customer service immediately.
- Verify all package contents are present as listed in Section 2.2.
3.2 Battery Installation (for Digital Keypad)
The digital keypad requires batteries for operation. While the product specifications state "Batteries Required? No", this refers to batteries not being included in the package. You will need to install 4 AA batteries (not included) into the battery compartment, typically located on the inside of the safe door or behind the keypad panel. Refer to the specific instructions in the included user manual for exact battery compartment location and installation.
The included Emergency Battery Box can be used to power the keypad externally if the internal batteries are depleted, allowing you to open the safe and replace them.
3.3 Mounting the Safe
The Karbeen safe is designed for both wall and floor mounting to enhance security. Use the provided expansion screws to secure the safe to a solid surface. Ensure the mounting location is discreet and structurally sound.
- Choose a suitable location for mounting, considering both security and accessibility.
- Position the safe and mark the drilling points through the pre-drilled holes in the back or bottom of the safe.
- Drill pilot holes into the wall or floor using an appropriate drill bit size for the expansion screws.
- Align the safe with the drilled holes and insert the expansion screws.
- Tighten the screws securely to firmly anchor the safe.
- Attach the non-slip pads to the bottom of the safe if not mounting, or to protect surfaces if desired.
3.4 Setting Your Personal Code
Refer to the detailed graphic user manual included in your package for specific instructions on how to set your initial personal access code. This typically involves pressing a reset button (often inside the safe door), entering a new code, and confirming it.
Important: After setting your code, test it multiple times with the safe door open to ensure it works correctly before closing the safe.

5. Maintenance

To maintain the appearance and functionality of your safe:

- Do not spray cleaning solutions directly onto the keypad or electronic components.
- Periodically clean the interior with a dry, soft cloth to remove dust.
5.2 Battery Replacement
The safe's digital keypad is powered by internal batteries. A "Low Battery Reminder" will alert you when the batteries are running low. Replace all batteries simultaneously with new, high-quality AA alkaline batteries to ensure reliable operation. If the batteries completely deplete, use the emergency battery box or emergency keys to access the safe.
5.3 Key Storage
