This equipment generates and uses radio frequency energy 

which may interfere with residential radio and television 

reception if not properly installed and used in accordance with 

instructions contained in this manual. Reasonable protection 

against such interference is ensured, although there is no 

guarantee this will not occur in a given installation. If interference 

is suspected and verified by switching this equipment on and 

off, the user is encouraged to try to correct the interference 

by one or more of the following measures: Reorient the radio/

television receiver’s antenna, relocate the equipment with respect 

to the receiver, plug the equipment and receiver into separate 

circuit outlets. The user may also wish to consult a qualified 

radio/television technician for additional suggestions. This 

equipment has been fully tested and complies with all limits for 

Class B computing devices pursuant to part 15 FCC Rules and 

Regulations.

Should your equipment cause trouble on your line which may 

harm the telephone network, the telephone company, where 

practicable, may notify you that temporary discontinuance of 

service may be required. Where prior notice is not practicable 

and the circumstances warrant such action, the telephone 

company may temporarily discontinue service immediately.

The telephone company may make changes in its 

communications facilities, equipment, operations or procedures 

where such action is required in the operation of its business. If 

these changes are expected to affect the use or performance 

of your telephone equipment, the telephone company will 

likely give you adequate notice to allow you to maintain 

uninterrupted service.
