5.3 Maintenance

Chemical and abrasive materials must not be used to clean the
GPS11 housing; if it is dirty, clean it with a soft, damp cloth.
Examine all cables for chafing or damage to the outer shield and,
where necessary, replace with genuine Apelco cables and resecure.
Ensure that any external plugs and sockets are kept clean and dry.
Use small amounts of a silicon based grease to prevent corrosion on
exposed connectors.
