Cautions
Caution of the products described in this document
The following precautions apply to the product described in this manual.
WARNING
Indicates a potentially hazardous situation which could result in death or serious injury and/or a fault in the
user’s system if the product is not used correctly.
Electric shock,
Damage
Before performing any operation described in this manual, turn off all the power supplies to the system.
Performing such an operation with the power on may cause an electric shock or device fault.
Electric shock,
Damage
Once the product has been turned on, do not touch any metal part of it.
Doing so may cause an electric shock or device fault.
CAUTION
Indicates the presence of a hazard that may cause a minor or moderate injury, damages to this product or
devices connected to it, or may cause to lose software resources and other properties such as data, if the
device is not used appropriately.
Cuts, Damage
Before moving the product, be sure to turn off all the power supplies and unplug the cables. Watch your step
when carrying the product. Do not use the product in an unstable location such as a place exposed to strong
vibration or a sloping surface. Doing so may cause the product to fall, resulting in an injury or fault.
Cuts
The product contains sharp edges that are left unavoidably exposed, such as jumper plugs.
Handle the product with due care not to get injured with such pointed parts.
Damage
Do not place anything on the product or expose the product to physical shocks. Do not carry the product
after the power has been turned on.
Doing so may cause a malfunction due to overloading or shock.
Damage
Since the product contains many electronic components, keep it away from direct sunlight, high temperature,
and high humidity to prevent condensation. Do not use or store the product where it is exposed to much dust
or a strong magnetic or electric field for an extended period of time. Inappropriate operating or storage
environments may cause a fault.
Damage
Use the product within the ranges given in the specifications.
Operation over the specified ranges may cause a fault.
Damage
To prevent electrostatic breakdown, do not let your finger or other object come into contact with the metal
parts of any of the connectors. Before handling the product, touch a metal object (such as a door knob) to
discharge any static electricity from your body.
Cautions

Damage
When turning the power on or off, follow the relevant procedure as described in this document. Before
turning the power on, in particular, be sure to finish making all the required connections. Furthermore, be
sure to configure and use the product by following the instructions given in this document. Using the product
incorrectly or inappropriately may cause a fault.
Damage
Always turn the power off before connecting or disconnecting any cables from the product. When unplugging
a cable, unplug the cable by holding the connector part without pulling on the cable itself. Pulling the cable
itself or bending it may expose or disconnect the cable core, resulting in a fault.
Damage
Because the product has no casing, it is recommended that it be stored in the original packaging.
Transporting the product may cause a damage or fault. Therefore, keep the packaging materials and use
them when re-shipping the product.
