7. Operating Instructions
7.1. Data Transfer Mode (PC Mode)
In this mode, the docking station functions as an external multi-bay enclosure for your computer.
- Ensure the Clone/PC switch on the rear is set to PC.
- Connect the USB 3.0 cable from the docking station to your computer.
- Insert the desired hard drives into any of the four bays.
- Power on the docking station.
- Your computer will detect the drives as external storage devices. You can now access, transfer, and manage files as you would with any external drive.
7.2. Offline Clone Function
The offline clone function allows you to duplicate a source hard drive to up to three target hard drives without needing a computer connection.
Important Considerations:
- Ensure the target drive(s) have a capacity equal to or greater than the source drive.
- All data on the target drive(s) will be erased during the cloning process. Back up any important data before proceeding.
- Do not disconnect drives or power during the cloning process.
Steps for Offline Cloning:
- Ensure the docking station is powered off and disconnected from any computer.
- Insert the Source hard drive into Bay 1 (Source).
- Insert one, two, or three Target hard drives into Bays 2, 3, and/or 4 (Target).
- Ensure the Clone/PC switch on the rear is set to Clone.
- Power on the docking station.
- Press and hold the START button for approximately 3-5 seconds until the cloning progress LEDs begin to flash.
- The cloning process will begin. The progress LEDs (25%, 50%, 75%, 100%) will illuminate sequentially to indicate completion percentage.
- Once the cloning is complete, all progress LEDs will be solid, and the device will emit three short beeps.
- Power off the docking station before removing the drives.
8. Maintenance
Proper maintenance ensures the longevity and optimal performance of your device:
- Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use liquid cleaners or aerosols.
- Storage: When not in use, store the device in a cool, dry place away from direct sunlight and extreme temperatures.
