Safety Information
FCC Statement: Part 68
This equipment complies with FCC rules, Part 68. On the BOTTOM of 
this equipment is a label that contains, among other information, the 
FCC Registration Number and Ringer Equivalence Number (REN) for 
this equipment. If requested, provide this information to your telephone 
company. 
The (REN) is useful to determine the quantity of devices you may con-
nect to your telephone line and still have all of those devices ring when 
your number is called. In most, but not all areas, the sum of the RENs 
of all devices should not exceed 5.0. To be certain of the number of 
devices you may connect to your line, as determined by the REN, you 
should call your local telephone company to determine the maximum 
REN for your calling area. 
If this equipment causes harm to the telephone network, the Telephone 
Company may discontinue your service temporarily. If possible, they 
will notify you in advance. But if advance notice isnt practical, you 
will be notified as soon as possible. You will be advised of your right to 
file a complaint with the FCC. 
Your telephone company may make changes in its facilities, equip-
ment, operations, or procedures that could affect the proper operation 
of your equipment. If they do, you will be given advance notice to give 
you an opportunity to maintain uninterrupted service. 
If you experience trouble with this equipment, please contact the manu-
facturer for warranty/repair information. The Telephone Company may 
ask that you disconnect this equipment from the network until the prob-
lem has been corrected or until you are sure that the equipment is not 
malfunctioning.

cation means that the equipment meets telecommunications network 
protective, operation and safety requirements as prescribed in the 
appropriate Terminal Equipment Technical Requirements document(s). 
The Department does not guarantee the equipment will operate to the 
users satisfaction. 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 deg-
radation of service in some situations. 
Repairs to certified equipment should be coordinated by a representa-
tive designated by the supplier. Any repairs or alterations made by the 
user to this equipment, or equipment malfunctions, may give the tele-
communications 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 them-
selves, but should contact the appropriate electric inspection authority, 
or electrician, as appropriate. 
NOTICE
: The Ringer Equivalence Number (REN) assigned to each 
terminal device provides an indication of the maximum number of ter-
minals allowed to be connected to a telephone interface. The termina-
tion on an interface may consist of any combination of devices subject 
only to the requirement that the sum of the Ringer Equivalence Num-
bers of all the devices does not exceed 5.
