Interference to radio or television reception can be determined by turning the equipment off and on. If
interference is present, try the following:
•
Reorient the receiving antenna.
•
Relocate the equipment with respect to the receiver.
•
Move the equipment away from the receiver.
•
Plug the equipment into a different outlet so that the equipment and the receiver are on
different branch circuits.
•
Consult the dealer or an experienced radio/television technician.

Dial Line Jack Types
The Federal Communication Commission (FCC) is a telecommunications and standards organization
that specifies a series of registered jacks for use with a dial line network or General Switched
Telephone Network (sometimes referred to as PSTN). These jacks are designated as RJxxx-type jacks,
where RJ means Registered Jack and xxx specifies the jack series. For example, RJ11 indicates a
registered jack from series 11. Sometimes the jack designation is followed by a letter (ex: RJ11C) that
indicates the jack housing style. Jacks specified under FCC Part 68 fit into one of the following
categories: Permissive (voice) or Programmable (data)
6-Pin Voice Jack (Permissive)
This jack type primarily allows voice signals transmitted across lines designated for voice
transmission. This jack type also allows data signals to be transmitted across voice-grade lines.
8-Pin Data Jack (Programmable)
This jack type is designed to ensure voiceband data transmission integrity across an interface
cable. The jack is referred to as “programmable” because it contains a resistor that allows the
phone company to adjust for the optimum output power level before the DCE is connected to
the line. The following jack types can be used with your modem.
