Setup
Before using your Aegis Secure Key 3 NX, you must set up an Administrator PIN. This PIN is essential for accessing and managing the device.
- Initial Charge: Ensure the device is sufficiently charged. If the battery is completely empty, connect it to a USB port for approximately 4-5 hours to charge.
- Power On: Press the SHIFT button (often indicated by a key symbol) followed by the LOCK button. The LED indicators will illuminate.
- Set Administrator PIN:
- Refer to the Quick Start Guide included with your product for specific instructions on setting the Administrator PIN.
- The PIN must be between 7 and 16 digits long.
- Avoid simple, sequential, or repetitive numbers.
- Create User PIN (Optional): The device supports separate Administrator and User modes. An Administrator can create a User PIN for limited access. Consult the full user manual on the manufacturer's website for detailed steps.
Important: Remember your Administrator PIN. If forgotten, data recovery may not be possible without specific recovery pins or procedures outlined by the manufacturer.
