Issue 1, June 1984 
WARNING: 
This equipment generates 
and uses radio frequency energy and if 
not installed and used properly, that is, in strict accordance 
with the manufacturers instructions, 
may cause interference to 
radio and television reception. It has been type 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 
against such interference 
in a residential installation. 
How- 
ever, there is no guarantee that interference will not occur in a- 
particular installation. 
If this equipment does cause inter- 
ference to radio or television reception, which can be determined 
by turning the equipment off and on, 
the user is encouraged to 
try to correct the interference by one or more of the following 
measures: 
- Reorient the receiving antenna 
- Relocate the computer with respect to the receiver 
- Move the computer away from the receiver 
c - Plug the computer into a different outlet so that 
computer and receiver are on different branch circuits.. ., 
If necessary, the user should consult the dealer or an experi- 
enced radio/television 
technician for additional suggestions. 
The user may find the following booklet prepared by the Federal 
Communications Commission helpful: 
HOW to Identify and Resolve Radio-TV Interference
