• If, in the unlikely event that this equipment causes harm to the network, the tele-

 

phone company will notify you in advance that temporary discontinuance of ser-

 

vice may be required. But if advance notice isn't practical, the telephone

 

company will notify you as soon as possible. Also, you will be advised of your

 

right to file a complaint with the FCC if you believe it necessary.

 

• The telephone company may make changes to its facilities, equipment, operations

 

or procedures that could affect the operation of the equipment. If this happens

 

the telephone company will provide advance notice so you can make the neces-

 

sary modifications to maintain uninterrupted service.

REN

The REN is used to determine the quantity of devices that may be connected to the

 

telephone line. Excessive REN's on the telephone line may result in the devices not

 

ringing in response to an incoming call. Typically the sum of REN's 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 REN's) contact the local telephone company.

Canadian Telco Requirements

NOTICE: The Industry Canada label identifies certified equipment. This certification means that the equipment meets telecommunications network protective, operational and safety requirements as prescribed in the appropriate Terminal Equipment Techni- cal Requirements document(s). The Department does not guarantee the equipment will operate to the user's satisfaction.

Before installing this equipment, users should ensure that it is permissible to be con- nected 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 ser- vice 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.
