Patton Electronics

warrants all Model 2017RC components to be

free from defects, and will—at our option—repair or replace the product
should it fail within one year from the first date of shipment.

This warranty is limited to defects in workmanship or materials,

and does not cover customer damage, abuse or unauthorized
modification.  If this product fails or does not perform as warranted,
your sole recourse shall be repair or replacement as described above.
Under no condition shall

Patton Electronics

be liable for any damages

incurred by the use of this product.  These damages include, but are
not limited to, the following:  lost profits, lost savings and incidental or
consequential damages arising from the use of or inability to use this
product.  

Patton Electronics

specifically disclaims all other warranties,

expressed or implied, and the installation or use of this product shall be
deemed an acceptance of these terms by the user. 

1.1  RADIO AND TV INTERFERENCE

The Model 2017RC generates and uses radio frequency energy,

and if not installed and used properly—that is, in strict accordance with
the manufacturer's instructions—may cause interference to radio and
television reception.  The Model 2017RC has been tested and found to
comply with the limits for a Class A computing device in accordance
with the specifications in Subpart J of Part 15 of FCC rules, which are
designed to provide reasonable protection from such interference in a
commercial installation.  However, there is no guarantee that
interference will not occur in a particular installation.  

If the Model 2017RC does cause interference to radio or television

reception, which can be determined by turning the power off or
disconnecting the unit, the user is encouraged to try to correct the
interference by one of the following measures:  moving the computing
equipment away from the receiver, re-orienting the receiving antenna,
and/or plugging the receiving equipment into a different AC outlet (such
that the computing equipment and receiver are on different branches).

If the user detects intermittent or continuous product malfunction

due to nearby high power transmitting radio frequency equipment, the
user is advised to use data cables with an external outer shield bonded
to a metal or metalized connector, and to configure the rear card as
shown in Section 3.2 of this manual.
