1.1 RADIO AND TV INTERFERENCE
The Model 1050 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 1050 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 1050
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).
1.3 SERVICE
All warranty and non-warranty repairs must be returned freight
prepaid and insured to Patton Electronics. All returns must have a
Return Materials Authorization number on the outside of the shipping
container. This number may be obtained from Patton Electronics
Technical Service at (301) 975-1007; http://www.patton.com: or,

loopback test mode, LED indicators and a DCE/DTE switch. The
Model 1050 supports asynchronous RS-232 data rates to 38.4 Kbps.
Distances of 7 miles (11.2 km) (@ 1200 bps) are attainable over two
24 AWG (.5mm) twisted pair.
