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 222N9 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 222N9 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
222N9 does cause interference to radio or television reception, which
can be determined by disconnecting the RS-232 interface, 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 Patton
Technical Support.
