1.1 RADIO AND TV INTERFERENCE 

The Model 1140 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 1140 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 1140 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).
