1.1 WARRANTY STATEMENT
Patton Electronics warrants all Model 2720 Series components to be

use of this product. These damages include, but are not limited to, the fol-
lowing: 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. In the event that you detect intermittent or continuous product mal-
function due to nearby high power transmitting radio frequency equipment,
use only data cables with an external outer shield bonded to a metal or
metalized connector.
1.2 RADIO AND TV INTERFERENCE
The NetLink-T1™ Model 2720 Series generates and uses radio fre-
quency 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 2720 Series has been tested and
found to comply with the limits for a Class A computing device in accor-
dance 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 2720 Series causes
interference to radio or television reception, which can be determined by
disconnecting the cables, 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).
WARNING! This device is not intended to be con-
nected to the public telephone network in Europe.
