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

1.1  RADIO AND TV INTERFERENCE

The Model 222NRC 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 222NRC 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
222NRC does cause interference to radio or television reception, which
can be determined by turning the power off or disconnecting the
RS-232 interface, 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).

In the event that the user detects intermittent or continuous product

malfunction due to nearby high power transmitting radio frequency
equipment, the user is strongly advised to take the following steps:

1) Use only data cables with an external outer shield bonded to a 
metal or metalized connector, and...

2) Configure the rear card as shown in Section 3.3.1 in this
manual.
