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.
