MANUAL CHANGE

 INFORMATION

At Tektronix, we

 continually strive to

 keep up with latest electronic developments 

by 

adding

 circuit and component improvements to our instruments as soon as they 

are developed

 and

 tested.

Sometimes,

 due to printing and shipping requirements,

 we can’t get these 

changes

 immediately into printed

 manuals. Hence, your manual may contain new 

change

 information on following pages.

A

 

single change may

 affect several

 sections. Since the change information sheets 

are 

carried in the 

manual until

 all changes are permanently entered, some 

duplication may

 occur.

 If no such change pages appear following this page, your 

manual 

is 

correct

 as printed.

SERVICE

 

NOTE

Because

 of the universal parts procurement problem, some electrical

 parts in your 

instrument may be

 different from those described in the Replaceable Electrical Parts 

List. The parts 

used

 will in no way alter or compromise the performance or reliability 

of this

 instrument.

 They are

 installed when necessary to ensure prompt delivery to 

the 

customer. Order

 replacement

 parts

 from the Replaceable Electrical Parts List.
