1.1  RADIO AND TV INTERFERENCE

The Model 1088 generates and uses radio frequency energy, and

if not installed and used properlyÑthat is, in strict accordance with the
manufacturer's instructionsÑmay cause interference to radio and tele-
vision reception.  The Model 1088 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 1088 does
cause interference to radio or television reception, which can be deter-
mined by disconnecting the unit, the user is encouraged to try to cor-
rect the interference by one or more of the following measures:  mov-
ing the computing equipment away from the receiver, re-orienting the
receiving antenna and/or plugging the receiving equipment into a dif-
ferent 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 European Union
(EU).  A Certificate of Compliance is available by contacting Technical
Support.
