4.1 Battery Installation
The safe requires batteries for its electronic lock system. Locate the battery compartment, typically on the inside of the door or behind the keypad. Insert the required batteries, ensuring correct polarity. If the batteries are depleted, use the external battery box for temporary power access.
4.2 Initial Access and Keypad Activation
Upon first use, open the safe using the emergency key. Insert the key into the keyhole, turn it, and rotate the handle to open the door. This allows access to the interior for battery installation and initial programming.
4.3 Mounting the Safe
The safe can be mounted to a wall or floor for enhanced security. Locate the pre-drilled holes on the back and bottom of the safe. Use the provided expansion screws to secure the safe to a solid surface. Ensure the mounting location is structurally sound to support the safe's weight (approximately 45 pounds).

5.3 Opening the Safe
The safe can be opened using three methods:
- Fingerprint: Place a registered finger on the scanner. The safe will unlock in under 0.1 seconds upon successful authentication.
- PIN Code: Enter your registered PIN code on the keypad, then press '#' or 'OK'.
- Emergency Key: In case of battery failure or forgotten codes, use one of the emergency keys to manually open the safe.
5.4 Mute Mode
To activate or deactivate mute mode (silent operation):
- Press the '3' button on the keypad.
- Immediately press the '#' button.
- The safe will toggle between audible and silent modes.
5.5 Alarm System
The safe is equipped with an anti-theft alarm system. The alarm will activate under the following conditions:
- Six consecutive incorrect entries of the PIN code or fingerprint.

When triggered, the alarm buzzer will sound at over 70 decibels. To disarm the alarm, use a valid fingerprint, PIN code, or emergency key.

5.6 USB-C Emergency Power
If the internal batteries are completely depleted, preventing access, you can use a USB-C cable and an external power source (e.g., power bank) to temporarily power the safe. Connect the USB-C cable to the port on the keypad. This will provide enough power to enter your PIN or use your fingerprint to open the safe, allowing you to replace the internal batteries.
5.7 Internal Organization
The safe features two adjustable shelves for flexible storage. Inside the cabinet door, there are key hooks and pistol pockets for organized storage of smaller items.
