equipment malfunctions, may give the telecommunications company cause to
request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground
connections of the power utility, telephone lines and internal metallic water pipe
system, if present, are connected together. This precaution may be particularly
important in rural areas.
Users should not attempt to make such connections themselves, but should
contact the appropriate electric inspection authority, or electrician, as
appropriate.
NOTICE: The Ringer Equivalence Number (REN) assigned to each relevant
terminal device provides an indication of the maximum number of terminals
allowed to be connected to a telephone interface. The termination on an
interface may consist of any combination of devices subject only to the
requirement that the sum of the RENs of all the devices does not exceed 5.
The REN of this equipment is either marked on the unit or included in the new
style USA FCC registration number. In the case that the REN is included in the
FCC number, the user should use the following key to determine the value:
The FCC number is formatted as US:AAAEQ#TXXX.
# is the Ringer Equivalence Number without a decimal point (e.g. REN of 1.0
will be shown as 10, REN of 0.3 will be shown as 03). In the case of a Z ringer,
ZZ shall appear. In the case of approved equipment without a network interface
or equipment not to be connected to circuits with analog ringing supplied, NA
shall appear.
The REN is useful to determine the quantity of devices that may be connected
to the telephone line. Excessive RENs on the telephone line may result in the
devices not ringing in response to an incoming call. In most, but not all areas,
the sum of RENs of all devices that may be connected to a line, is determined
by the total RENs, contact the local telephone company.
