1.1 RADIO AND TV INTERFERENCE

The Models 3P-MF and 3P-MF9 generate and use 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 Models 3P-MF and 3P-MF9 have
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 3P-MF or 3P-MF9 do 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).

The Model 3P-MF Series

self powered short haul with an
face. Many laptops, notebooks and PC cards on the market supply inter­face that’s well below the specifications of the actual standard. The
Models 3P-MF (DB-25 connectors) and 3P-MF9 (DB-9 connectors) can
easily bridge that gap. Special versions also available.

Model 3P-MF is equipped with DB-25 connectors on each end; Model
3P-MF9 has DB-9 connectors. Each provides 9VDC to Patton’s interface
powered short hauls on pin 9. And both 120 VAC and 230 VAC wall­mount adapter versions are available.
