Precision 7 mm Connector Cleaning
Procedure

Cleaning the Center Collet While It Is in Place

You do not have to remove the center conductor collet to clean a
precision 7 mm connector.
With the center collet in place:
1. Place a lint-free cleaning cloth flat on a table.
2. Dispense a drop or two of isopropyl alcohol in the center of the cloth.
3. Retract the connector sleeve threads to expose the connector
interface.
4. Gently press the contact end of the connector into the moistened
cloth and rotate the connector. The cloth scrubs away dirt on the
connector interface without damaging it.
5. Blow the connector dry with a gentle stream of compressed air or
nitrogen.
6. When not in use, keep the cloth in a plastic bag or box so that it does
not collect dust or dirt.
For fixed connectors (connectors attached to a device that cannot be
freely moved):
1. Fold a lint-free cleaning cloth several times.
2. Moisten the cloth with isopropyl alcohol.
3. Press the moistened cloth against the connector interface and rotate
the cloth to clean the connector.
4. Blow the connector dry with a gentle stream of compressed air or
nitrogen.
