Talkswitch 48-CA User Manual page 137

Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local Telecommunications Company. The equipment
must also be installed using an acceptable method of connection. The customer should
be aware that compliance with the above conditions may not prevent degradation of
service in some situations.
Repairs to certified equipment should be coordinated by a representative designated
by the supplier. Any repairs or alterations made by the user to this equipment, or
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.
Caution: Users should not attempt to make such connections themselves, but should
contact the appropriate electric inspection authority, or electrician, as appropriate.
A label is located on the underside of the base unit containing both the FCC
registration number and Ringer Equivalency Number (REN) or the IC registration
number and Load Number. You must, upon request, provide this information to your
local telephone company.
The REN is used 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
should not exceed five (5.0). To be certain of the number of devices that may be
connected to a line, as determined by the total RENs, contact the local Telephone
Company.
This equipment is compatible with inductively coupled hearing aids.
