Preventive maintenance

The AP70/AP80 control units do not contain any fi eld serviceable components, therefore the
operator is required to perform only a very limited amount of preventative maintenance.
To prevent UV damage to the plastic bezel and rubber keys, it is recommended that the sun
cover (option) be fi tted when the unit is not in use for an extended period.

Simple maintenance procedures

Cleaning the display unit
The supplied cleaning cloth should be used to clean the screen where possible. Use plenty of
water to resolve and remove salt remains. Crystallized salt may scratch the coating if using a
damp cloth. Apply minimal pressure to the screen.
Where marks on the screen can't be removed by the cloth alone, use a 50/50 mixture of warm
water and isopropyl alcohol to clean the screen. Avoid any contact with solvents (acetone,
mineral turpentine etc.), or ammonia based cleaning products, as they may damage the anti-
glare layer, plastics bezel, or rubber keys.
Checking the connectors
The connectors and computer terminals should be checked by visual inspection only.
Push the connector plugs into the connector. If the connector plugs are equipped with a lock;
ensure that this is in the correct position.

Restoring factory default settings

A default restore will reset the memories to factory settings.
The fi rst time the autopilot system is started and after restore, it will run through the
automatic setup-procedure.
 Note:
Unless you need to clear all stored values during the installation set-up procedure, you
should not perform a restore of factory settings.
