1.0 WARRANTY INFORMATION

warrants all Model 593/25, 593/45, and 593/TB
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 593/25, 593/45, and 593/TB 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 593/25,
593/45, and 593/TB has been tested and found to comply with the lim­its for a Class Acomputing 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 593/25, 593/45, and 593/TB does
cause interference to radio or television reception, which can be deter­mined by disconnecting the RS-485 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). ACertificate of Compliance is available by contacting Technical
Support.
