Safety Requirements
ARRIS Telephony Modems comply with the applicable requirements
for performance, construction, labeling, and information when used as
outlined below:
CAUTION
Risk of damage
Make sure that the existing wires providing telephone service are phys-
ically disconnected 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 will result in damage to the
Telephony Modem.
Connect only DC or AC power, not both, to the TM512. Connecting
both supplies may cause a reset upon loss of AC power.
Do not locate the equipment within 6 feet (1.9m) of a flame or ignition
source (e.g. heat registers, space heaters, fireplaces, etc.), to avoid dam-
age or injury from battery explosion.
Do not use product near water (i.e. wet basement, bathtub, sink or near
a swimming pool, etc.), to avoid risk of electrocution.
Avoid using and/or connecting the equipment during an electrical
storm, to avoid risk of electrocution.
