Informations importantes sur la sécurité
- Installation de la batterie : Ensure correct polarity when installing 4 AAA batteries. Do not mix old and new batteries or different types of batteries.
- Alimentation de secours: In case of battery depletion, use the provided mechanical key or a Type-C USB power source for emergency access.
- Default Code Vulnerability: WARNING: Some units may retain a factory preset code (e.g., 1234567890 followed by the checkmark) that can unlock the door regardless of user-defined codes. It is crucial to test your lock thoroughly after setting your own codes to ensure this default code is not active. If it is, contact customer support immediately as this poses a significant security risk.

- Installez le loquet : Insert the latch mechanism into the door edge. Ensure the latch bolt faces the correct direction for your door swing.
- Install Outside Knob: Place the exterior keypad knob through the door, aligning it with the latch.
- Installer la plaque de montage : Secure the mounting plate to the door frame, ensuring it is flush and stable.
- Pass the Cable: Carefully route the power cable from the exterior knob through the designated hole in the mounting plate to the interior side.
- Connectez le câble d'alimentation : Connect the power cable to the interior knob's circuit board. Ensure a secure connection.
- Align Inside Knob: Align the interior knob with the mounting plate and the spindle from the latch.
- Install Inside Knob: Secure the interior knob to the mounting plate using the provided screws.
- Restaurer les paramètres d'usine : After installation, it is highly recommended to perform a factory reset to clear any pre-existing codes and ensure proper functionality. Refer to the "Operating Instructions" section for details on factory reset.
Remarques importantes :
- The lock is auto-lock by default. The knob cannot rotate the latch without a code or key.
- The mechanical key requires slightly more force than a common mechanical lock due to the independent design of the knob and key mechanism.
Mode d'emploi
This section details how to use your BOTHSTAR Keypad Door Knob.
1. Définition des codes utilisateur
Each keypad can store up to 50 unique user codes. Refer to the specific programming instructions in the included quick start guide for detailed steps on adding, deleting, and modifying user codes. The anti-peeping feature allows you to enter random digits before or after your actual code to prevent others from guessing your entry sequence.

2. Mode de verrouillage automatique
The lock can be configured to automatically lock after a set period. The default auto-lock time is typically 4 seconds, but this can be adjusted from 2 seconds up to 12 hours. This feature ensures your door is always secured after closing.
3. Manual Lock Mode (Passage Mode)
For situations with frequent entry and exit, you can activate manual lock mode (also known as passage mode). In this mode, the door will remain unlocked until manually locked, allowing free passage without requiring a code each time. Consult your quick start guide for instructions on enabling/disabling this mode.

4. Password Synchronization
When the sync switch is activated, any code changes made on one side of the lock will automatically update on the other side, simplifying code management for both exterior and interior keypads.
5. Low Battery Indicator & Emergency Power
The lock features a low battery indicator to alert you when batteries need replacement. In case of complete battery depletion, you can use the mechanical key for entry or connect a Type-C USB power source to the emergency charging port to temporarily power the lock and enter your code.
6. Mode silencieux
The lock can be set to silent mode, disabling audible feedback for keypad presses and locking/unlocking actions. This is useful for quiet environments or late-night entries.
7. Remote Code Generation
The system supports generating unique remote codes via a dedicated website interface. These codes can be configured with specific unlock times or usage limits and do not require internet connectivity at the lock itself for activation. This allows for granting temporary access to guests or service providers.

Entretien
- Remplacement de la batterie : Replace all 4 AAA batteries when the low battery indicator activates. Use high-quality alkaline batteries for optimal performance and longevity.
- Nettoyage: Clean the keypad and knob surfaces with a soft, damp Chiffon. Évitez les nettoyants abrasifs ou les solvants qui pourraient endommager la finition ou les composants électroniques.
- Lubrification: Periodically check the latch mechanism for smooth operation. If necessary, apply a small amount of graphite lubricant to the latch bolt. Do not lubricate the electronic components.
Dépannage

- Check batteries: Replace all 4 AAA batteries if they are low or depleted.
- Ensure correct code: Verify you are entering the correct user code followed by the checkmark.
- Emergency power: If batteries are completely dead, use the mechanical key or connect a Type-C USB power source.
- Lock does not engage/disengage properly:
- Check alignment: Ensure the lock components are correctly aligned and not obstructed.
- Door frame: Verify the strike plate and strike box are properly installed and aligned with the latch bolt.
- Mechanical issue: Inspect the latch mechanism for any physical damage or debris.
- Factory preset code (e.g., 1234567890) still works after setting new codes:
- This indicates a potential security vulnerability. Perform a factory reset as per the quick start guide. If the issue persists, immediately contact BOTHSTAR customer support for assistance.
