Special Features RM 8xxx
Purchasing an RM 7xxx or
an RM 8xxx, there is the
option of an electrical door-
lock. When the fridge door is
closed, it is kept shut by a
magnetic sealing, but not
locked. Starting the engine,
the electronics will
automatically lock the fridge
door, due to the recognition
of the D+ signal. Also with
this kind of door lock,
changing the door rabbet is
not possible.
