CORRECTIVE MAINTENANCE
CAUTION. A 2% RMAflux content solder is recommended for making repairs in
this instrument. Cleaning of rosinresidue is not recommended. Most cleaning
solvents tend to reactivatethe rosin and spread it under components whereit
may cause corrosionunder humid conditions. The rosin residue, if left alone,
does not exhibit these corrosiveproperties.
NOTE. No repairshould be attempted during the warranty period.
Obtaining ReplacementParts
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 Tektronixinstruments are sometimes made to accommodate
improved components, asthey become available, and to improve circuit
performance. Therefore, it is important to include the following information
when orderingparts:
1. PartNumber
2. Instrument Typeor Number
3. Serial Number
4. Modification or Option Number (ifapplicable)
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 th ep art does not directly replace
the old one, the local Tektronixfield office or representative will contact the
customer. After any repair or modification of the i nstrument, circuit readjust-
ment may be required.
