5. Operating Instructions
5.1. Power Supply
The safe is powered by 4 x AA 1.5V alkaline batteries (not included). The battery compartment is located on the inside of the safe door. Insert the batteries according to the polarity indicators (+/-).
A red LED light on the keyboard will illuminate to warn you when the batteries are low and need replacement.
5.2. Setting Programmable Codes
The safe features two programmable opening codes: a master code and a user code. Both codes can be 3 to 6 digits long, offering 1 million possible combinations.
Refer to the specific instructions provided on a separate sheet or within the safe for the exact procedure to set or change these codes, as it typically involves pressing a reset button inside the safe and then entering the new code on the keypad.
5.3. Opening the Safe with Electronic Lock
- Enter your programmed master or user code on the electronic keypad.
- If the code is correct, a green LED will light up.
- Within 5 seconds, turn the rotary knob clockwise to open the safe door.
If three incorrect codes are entered consecutively, the safe's lock will temporarily activate a protective mode, preventing further attempts for a short period.
5.4. Emergency Opening
In case of forgotten code, worn-out batteries, or keypad malfunction, the safe can be opened using the emergency key.
- Locate the emergency keyhole, usually hidden behind a small cover on the keypad panel.
- Insert one of the provided emergency keys into the keyhole.
- Turn the key clockwise while simultaneously turning the rotary knob to open the safe door.
- Once the safe is open, you can replace the batteries or reset the code as needed.
