FCC Statement (Part 15) - Radio Frequency Interference
The DST1 Digital StereoTuner generates and uses radio frequency energy and if
not installed and used in strict accordance with the manufacturer's instructions,
may cause interference to radio and television reception.Testing is being con-
ducted for compliance with the limits for a Class B device in accordance with the
specifications in Part 15 of the FCC Rules and Canadian D.O.C. regulations.This
testing is designed to provide reasonable protection against such interference.
However,there is no guarantee that interference will not occur in a particular in-
stallation. If this equipment does cause interference to radio or television recep-
tion, which can be determined by turning the DST1 unit off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
- Reorient the radio orTV receiving antenna.
- Relocate the DST1 unit with respect to the radio orTV receiver or vice-versa.
- Plug the DST1 unit into a different outlet so that it and the radio orTV receiver
are on different branch circuits.
If necessary,the user should consult the dealer or an experienced radio/television
technician for additional suggestions.The user may find the following flyer, "Inter-
ference: Defining the Source," helpful.This flyer was prepared by the Federal Com-

and unwind the lead from the loop.
2. Connect the antenna leads to the terminals marked AM LOOP
(AM and GND).
3. Snap the antenna into the base to form a free-standing unit.
4. Position the antenna for best reception. If desired, the antenna may be
permanently mounted using screws through the two holes in the base.
Audio Connections
An audio patch cable is provided to make audio connections.
1. Connect the two RCA plugs from one end of the cable to the R and L
STEREO terminals on the DST1. (Note: For mono applications, connect
one end of cable to the MONO terminal.)
