Please read the Tu manual thoroughly and familiarize yourself with the product before use.
Only use the Tu in an area with sucient ventilation. Make sure that the fan is not
obstructed to ensure proper air ow, which is essential for heat dissipation. Do not leave or
use the Tu near a heat source or direct sunlight.
Avoid using the Tu in extremely hot or cold environments as it will increase the likelihood
of premature drive failure. The safe operating temperature ranges from 40F - 95F (4.4C-35C).
Avoid using the Tu in humid environments. Moisture and condensation can accumulate in
the drive and damage the electrical components, resulting in unit failure and catastrophic
data loss.
Make sure to transport your Tu with care. Hard drives are sensitive to shock and rough
handling, and can result in degrading performance or disk failure.
Keep the Tu away from liquids and moisture. Exposure to liquids on the Tu can result in
damaging the unit, electric shock, and result in a re hazard. If your Tu gets wet while it is
still o, do not turn it on.
In the case of any issues with the device, do not attempt to repair or open the Tu yourself.
Doing so can result in personal injury, damaging the device, and will void the warranty. If you
have any issues, please contact CalDigit technical support.
All electrical devices are susceptible to failure. In order to protect yourself against sudden
data loss, it is highly recommended that you create at least two backups of your data. If you
will be sending a drive back to CalDigit for service, please make sure you have backed up
your data beforehand. CalDigit cannot guarantee the integrity of data on drives that are
returned to us. CalDigit cannot make provisions for data recovery or be held liable for any
data loss.
