imited Warranty For Conrad-Johnson Components
L
conrad-johnson design, inc. will provide service under warranty to the
original owner on products sold new in the United States for the lesser
period of three years from the date of purchase by the original purchaser,
or five years from the date of shipment to the authorized conrad-johnson
dealer. During the warranty period, conrad-johnson will repair defective
units without charge for labor or parts (with the exception of vacuum
tubes and batteries).
Exclusions. The following are not covered under this warranty:
a) Units which have been damaged by misuse, abuse, or accident.
b) Units which have been modified, altered, or improperly repaired by
anyone not specifically authorized by conrad-johnson design, inc.
c) Units not purchased from an authorized conrad-johnson dealer in the
United States for use in the United States.
d) Normal wear.
e) Incidental or consequential damages are not covered under this
warranty. Some states do not allow the exclusion of incidental or
consequential damages, so this exclusion may not apply to you.
Obtaining Warranty Service: To obtain warranty service, the unit must
be shipped, along with evidence of purchase, in factory packing to
conrad-johnson design (or designated service center) with freight and
insurance prepaid by the owner. After repair, the unit will be returned with
freight and insurance prepaid by conrad-johnson design to any destination in the United States.
All implied warranties, including merchantability and fitness for a particular purpose are limited in duration to the duration of this express
warranty. Some states do not allow limitations on the duration of implied
warranties so the above limitations may not apply to you.
This warranty gives you specific legal rights and you may also have
other rights which vary from state to state.
Conrad-Johnson products purchased outside the United States are
covered by warranty terms of the importing distributor in the country in
which the product was originally purchased, which may differ from the
terms set out herein. Importing distributors are not obligated to provide
warranty service for products originally purchased outside their country.
Conrad-Johnson will provide warranty service for products outside the

The Service Department can also be reached by phone at 703-6988581, or by fax at 703-560-5360
If your conrad-johnson audio component requires service, repack it
using the original box and packing material and ship to the Service
Department address above. Boxes and packing materials can be obtained from our service department for a nominal charge, if you no longer
have yours. Include with the unit a note describing the problem you are
having in as much detail as possible. It is especially important for our
technician to know if the problem is intermittent. If you want an estimate
of cost for out of warranty service, be sure to request it in this note. Be

Electromagnetic Interference (EMI)
Because the DR-1 dissipates very little heat, ventilation is not an important consideration, allowing greater flexibility for custom or built-in installations. Of course, reasonable judgement must be exercised to see that
the DR-1 does not obstruct ventilation required by amplifiers or other
equipment in the system. The unit must be mounted horizontally.
All DR-1s sold in the United States are configured for operation on a
60Hz ac power line producing between 108 and 126 volts. Export
versions of the DR-1 will have the correct operating voltage and frequency clearly marked on the back panel of the unit, near the ac power
cord. In all cases, the actual line voltage should be within + 5/- 10% of
the nominal rated voltage.
Considerable care has been taken in the design of the DR-1 to minimize
it’s susceptibility to radio frequency interference and other forms of EMI.
Choice of materials, physical layout, grounding practice, and power
supply design have all been specified with a view to reducing the impact
of electromagnetic fields on the performance of this unit, and to assure
that it does not radiate fields that might interfere with the operation of
other units.
Care in installation can often avoid EMI induced problems. The following
practices should generally be observed in any application, and will be
especially important where EMI may be a problem.
Audio interconnect cables should be kept as short as possible (3 meters
or less), and shielded cable should be used (cable which has two center
conductors, and a separate external shield connected at only one end).
Physical location and cable "dress" can be an important factor in minimizing hum pickup. The installation should situate the DR-1 away from
the preamplifier and other sources. Power (ac mains) cords should be
dressed to remain at least 4" (100mm) away from audio signal cables,
and from coaxial digital cables.
