separately ground any amp unit away
from the ground of this navigation sys-
tem. Connecting grounds together can
cause a fire and/or damage the products if
their grounds became detached.

use a fuse of the rating prescribed on this

! When disconnecting a connector, pull the
connector itself. Do not pull the lead, as
you may pull it out of the connector.

cause a short circuit.

the corresponding colored port, i.e., blue

etc.
