Calibrating the Switch

No calibration is required.

Maintaining the Switch

Clean the connector ends with a lint-free tissue and alcohol before every mating. See the
Cleaning Connectors section.
Clean the internal connectors and the panel-mounted connector bulkheads periodically or
when high losses are suspected. The internal connectors can be accessed by removing the
connector panel:
1. Remove the retaining screws of the connector panel.
2. Slowly pull the panel out to the full extent of its guide rails (Figure 13).
3. Remove the connectors from the connector bulkheads.
4. Clean the connector ends and the bulkhead mating sleeves with a lint-free tissue and
alcohol.
5. Reinstall the connectors into the bulkheads.
