Important customer information
To avoid electric shock, use caution when connecting cables.
For example, do not connect safety extra-low voltage (SELV)
circuits to telephone-network voltage (TNV) circuits. LAN ports
contain SELV circuits, and WAN ports contain TNV circuits.
Some LAN and WAN ports both use RJ-45 connectors.
To avoid electric shock, do not operate the product or connect
or disconnect cables during electrical storms. To avoid electric
shock, do not use this product in or near water.
To reduce the risk of fire or overheating, keep this product in
well-ventilated areas, away from radiators or other heat
sources. Do not block cooling vents.
The plug-socket combination must be accessible at all times
because it serves as the main power-disconnecting device.
Use only the manufacturer-provided AC adaptor approved for
use with this product. Use of another AC adaptor may cause a
fire or explosion.

controls that are covered by the operating instructions,
since improper adjustment of other controls may result in
damage and will often require extensive work by a qualified
technician to restore the product to normal condition
