Safety Warnings
Warning
The ports labeled “Ethernet,” “10BaseT,” “Token Ring,” “Console,” and “AUX” are safety
extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV
circuits. Because the BRI circuits are treated like telephone-network voltage, avoid
connecting the SELV circuit to the telephone network voltage (TNV) circuits.
Statement 22
Warning
Connect the device to a grounded power outlet.
Statement 25
Warning
There is the danger of explosion if the battery is replaced incorrectly. Replace the battery
only with the same or equivalent type recommended by the manufacturer. Dispose of used
batteries according to the manufacturer’s instructions.
