1.0  WARRANTY INFORMATION

Patton Electronics warrants all Model 2703 components to be

free from defects, and will—at our option—repair or replace the prod-
uct 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 modifi-
cation.  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 consequen-
tial 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 2703 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 tele-
vision reception.  The Model 2703 has been tested and found to com-
ply 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 interfer-
ence will not occur in a particular installation.  If the Model 2703 does
cause interference to radio or television reception, which can be deter-
mined by disconnecting the cables, the user is encouraged to try to
correct the interference by one or more 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).

1.2  CE NOTICE

The CE symbol on your Patton Electronics equipment indicates

that it is in compliance with the Electromagnetic Compatibility (EMC)
directive and the Low Voltage Directive (LVD) of the Union European
(EU).  A Certificate of Compliance is available by contacting Technical
Support.
