Caring for Connectors

Cleaning

connector to clean the interior surfaces. Use an illuminated magnifying glass or
microscope to see clearly the areas you wish to clean.

Drying Connectors

When you have cleaned a connector, always be sure that it is completely dry before
reassembling or using it. Blow the connector dry with a gentle stream of clean
compressed air and inspect it again under a magnifying glass to be sure that no
particles or alcohol residues remain.
