Users in the U.S.A.
Supply a suitable table, cabinet, or desk. See Specifications (p. 103) for unit's dimensions and weight.
Order Information
Only a single line, touch tone or rotary telephone set is to be used.
Order an RJ11-C modular jack (USOC code), which should be installed by the phone company. If
the RJ11-C jack is not present, installation cannot occur.
Order a normal business line from your telephone company's business representative. The line
should be a regular voice grade line or equivalent. Use one line per unit.
NOTE: Canon recommends an individual line following industry standards [e.g., the 2500 (Touch tone)
or 500 (Rotary/Pulse Dial) telephones]. A dedicated extension off a PBX unit without "Call
Waiting" can be used with your FAX unit. Key telephone systems are not recommended
because they send non-standard signals to individual telephones for ringing and special
codes, which may cause a FAX error.
Power Requirements
This equipment should be connected to a standard 120 volt AC, three-wire grounded outlet only. Do not
connect this unit to an outlet or power line shared with other appliances that cause "electrical noise." Air
conditioners, electric typewriters, copiers, and machines of this sort generate noise which often
interferes with communications equipment and the sending and receiving of documents.
