Safety Requirements
ARRIS Telephony Modems comply with the applicable requirements for per-
formance, construction, labeling, and information when used as outlined
below:
CAUTION
Risk of shock
Mains voltages inside this unit. No user serviceable parts inside. Refer ser-
vice to qualified personnel only!
CAUTION
Risk of damage
Connecting the Telephony Modem to existing telephone wiring should be
performed only by a professional wiring technician.
The existing wires providing telephone service must be physically discon-
nected from the incumbent service provider’s network interface device. This
is a physical break in the connection, not just a discontinuation of service.
Failure to do so may result in damage to the Telephony Modem.
