Operating Instructions
Unlocking Methods
Your Thmosz safe offers three convenient ways to unlock it:
- Daily Access (Digital Keypad): Enter your personal 1-8 digit password, then press "#" to confirm. Turn the knob clockwise to open the safe.
- First Time Operation / Forgotten Passcode (Emergency Key): If you forget your password or for initial setup, remove the cover over the emergency keyhole (often disguised as a decorative emblem). Insert the emergency key and turn it counter-clockwise while simultaneously turning the knob clockwise to open the safe.
- Emergency Use (Lost Key + Dead Batteries): If batteries are dead and you cannot locate your emergency key, connect the external battery box to the port on the keypad. This will provide temporary power, allowing you to enter your password and open the safe.

Using the Hidden Lock Box
The lower compartment of the safe includes a hidden steel lock box for extra security. This box is ideal for storing highly sensitive documents or small, high-value items. It is secured with its own key.

Adjusting the Removable Shelf
The upper compartment features a removable shelf, allowing you to customize the interior space to accommodate items of various sizes. Simply lift and remove the shelf as needed.

Anti-Theft Alarm System
The safe is equipped with a dual anti-theft alarm system:
- Password Error Alarm: If an incorrect password is entered 3 consecutive times, the system will lock and sound an alarm for 60 seconds.
- Vibration Alarm: If the safe detects violent movement or attempts to pry it open while locked, the alarm will sound.
To stop the alarm, enter the correct password.

Maintenance
- Cleaning: Wipe the exterior with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Battery Replacement: Replace batteries annually or when the low battery indicator appears on the keypad to ensure continuous operation. Use 4 AA batteries.
- Key Care: Keep emergency keys clean and dry. Do not force keys into the lock.
