    General Use Precautions

    To avoid damage, do not expose the device to temperatures outside the following ranges:

    Always unplug the device from the electrical outlet if there is a risk of lightning or if it will be unused for an extended period of time. Otherwise, there is an increased risk of electrical shock, short-circuiting or fire.

    Do not use the product near electrical appliances such as televisions, radios or speakers. Doing so may cause interference which can adversely affect the operation of the appliances.

    Do not place the device near sources of magnetic interference, such as computer displays or speakers. Magnetic interference can affect the operation and stability of hard drives.

    Do not place objects on top of the device.

    Protect your device from excessive exposure to dust during use or storage. Dust can build up inside the device, increasing the risk of damage or malfunction.

    Do not block any ventilation openings on the device. These help to keep the device cool during operation. Blocking the ventilation openings may cause damage to the device and cause an increased risk of short circuiting or fire.

    Safety Precautions

    • Read this user guide carefully and follow the recommended steps for assembly.
    • Use proper anti-static precautions while installing drives into this enclosure. Failure to do so can cause damage to your drive mechanisms and/or the enclosure.
    • Do not attempt to disassemble or modify the device. To avoid any risk of electrical shock, fire, short-circuiting or dangerous emissions, never insert any metallic object into the device. If it appears to be malfunctioning, please contact technical support.
    • Never expose your device to rain, or use it near water or in damp or wet conditions. Never place objects containing liquids on the drive, as they may spill into its openings. Doing so increases the risk of electrical shock, short-circuiting, fire or personal injury.

    4.1 Troubleshooting

    • Begin your troubleshooting by verifying that the power cable is connected to the OWC Drive Dock and to a power source. If the power cable is connected to a power strip, make sure that the power strip is switched on. Next, verify that both ends of the data cable are properly plugged into the system and the OWC Drive Dock. If you are still having trouble, try connecting a different type of data cable and see if the Drive Dock works properly. You can also connect the device to a different system.
    • If issues continue to occur, please know that OWC support is here to help. Contacting support information can be found in section 4.3. Please have your serial number ready which is located on the bottom of the OWC Drive Dock and printed on the original packaging.

Any data loss or corruption while using the OWC Drive Dock is the sole responsibility of the user, and under no circumstances may OWC, its parents, partners, affiliates, officers, employees, or agents be held liable for loss of the use of data including compensation of any kind or recovery of the data.
