2. Setup and Compatibility
Before using your security cable, ensure your device has a compatible security slot. This cable is designed for devices with 2.5mm x 6mm Nano-Lock slots. It is also compatible with devices featuring Kensington-style security slots. Please note, it is not valid for T-LOCK or WEDGE slots.

The cable comes with a default combination, typically 0000. It is highly recommended to change this combination immediately after initial setup for enhanced security.
3. Operating Instructions

- Set the combination dials to your current code (default is 0000).
- Insert the lock head into the security slot on your device.

3.2. Setting or Resetting the Combination
It is crucial to set a new, memorable combination immediately after acquiring the cable. Follow these steps carefully:
- Set the lock to the open position by dialing the current combination (default is 0000).
- Locate the reset mechanism. On this model, this typically involves pinching the top of the cable where it meets the lock and pulling it down slightly.
- While holding the reset mechanism (cable pulled down), set your desired new 4-digit combination on the dials. Choose a combination that is easy for you to remember but difficult for others to guess.
- Release the reset mechanism. The new combination is now set.
- Scramble the dials to test the new combination. Ensure it unlocks only with your new code.

4. Maintenance
- Keep the combination dials clean and free from dust or debris. Use a soft, dry cloth for cleaning.
- Avoid exposing the lock mechanism to excessive moisture or extreme temperatures, which can affect its functionality.
- Do not apply excessive force when inserting or removing the lock head from the security slot.
- Regularly check the cable for any signs of wear or damage. If the cable or lock mechanism appears compromised, replace the unit.
5. Troubleshooting
5.1. Lock Not Engaging or Disengaging
- Incorrect Combination: Ensure the correct 4-digit combination is precisely aligned on the dials.
- Improper Insertion: Verify that the lock head is fully inserted into the security slot and rotated correctly (90 degrees) to engage.
- Slot Compatibility: Double-check that your device has a Nano-Lock (2.5x6mm) or compatible Kensington-style slot. This cable is not compatible with T-Lock or Wedge slots.
- Debris in Slot: Inspect the device's security slot for any obstructions that might prevent proper insertion.
5.2. Cannot Remember Combination
Unfortunately, if you have forgotten your combination and did not record it, there is no master key or backdoor to reset the lock without knowing the current code. The only way to regain access is to try all 10,000 possible combinations (0000-9999), which is time-consuming. It is highly recommended to store your combination in a secure, memorable location.
