Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote
risk of electric shock from lightning.
Statement 1038
Warning
To report a gas leak, do not use a telephone in the vicinity of the leak.
Statement 1039
Warning
To avoid electric shock, 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. Use caution when connecting cables.
Statement 1021
Warning
Hazardous network voltages are present in WAN ports regardless of whether power to the router is
OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching
cables, detach the end away from the router first.
