+ All variable and adjustable resistors have characteristic curve B, unless other-
wise noted
* The components identitied by B4 in this basic schematic diagram have been
carefully factory-selected for each set in order to satisty regulations regarding | The symbol -=# display ts on the component side
X-ray radiation
Should replacement be required, replace only with the value originally used The components identified by shading and mark A ate
critical for safety Replace only with part number specified
The symbol -#=4 indicate fast operating fuse
Replace only with fuse of same rating as marked
+ When replacing components identified by [@ , make the necessary adjust-
ments indicated If results do not meet the specified value, change the compo-
nent identified by Bq and repeat the adjustment until the specified value Is
achieved
(Refer to R530 and R531 adjustment on Page 14 - 15)
