Cleaning Care for Video Heads 
 
(a) Video Head Cleaning: Your TV/VCR Combination will not normally 
require head cleaning; however, it is possible that the heads may become 
clogged when playing an old or damaged tape. If the image on your 
screen resembles the photograph here during playback, the heads may 
require cleaning. 
(b) Cleaning the Heads: It is recommended that head cleaning be 
performed by a qualified service technician. Please contact your nearest 
dealer. An alternate solution is to obtain a head cleaning cassette. There 
are many types of cleaning cassettes, so be sure to follow the cleaning 
instructions carefully, excessive use of the cleaning cassette could shorten 
head life. Use this cassette only when a head clogging symptom occurs.
