CORRECTIVE MAINTENANCE
CAUTION. A 2% RMA flux content solder is recommended for making repairs in
this instrument. Cleaning of rosin residue is not recommended. Most cleaning
solvents tend to reactivate the rosin and spread it under components where it
may cause corrosion under humid conditions. The rosin residue, if left alone,
does not exhibit these corrosive properties.
NOTE. No repair should be attempted during the warranty period.
Obtaining Replacement Parts
Replacement parts are available through the local Tektronix, Inc., field office or
representative. However, many common electronic parts are available through
local sources. Using a local source, where possible, will eliminate shipping
delays.
Changes to Tektronix instruments are sometimes made to accommodate
improved components, as they become available, and to improve circuit
performance. Therefore, it is important to include the following information
when ordering parts:
1. Part Number
2. Instrument Type or Number
3. Serial Number
4. Modification or Option Number (if applicable)
If an ordered part has been replaced with a new or improved part that is a direct
replacement, the new part will be shipped. If the part does not directly replace
the old one, the local Tektronix field office or representative will contact the
customer. After any repair or modification of the instrument, circuit readjust-
ment may be required.
