In case more than one CDU is installed, only one CDU is allowed to be
assigned master control at a time, whereas all other CDUs operate as a
remote unit.
Only from the master CDU, the operator can access the operating and
service menus, acknowledge or mute alerts and scroll through the alert
list.
Remote CDUs permanently display speed and distance. The only keys
functional at a remote CDU are the
DIM-
/
DIM+
keys to adjust the bright-
ness level, the
UP
and
DOWN
keys to scroll through the main display
pages and the
MASTER
key, which requests master control to be trans-
ferred to this CDU.
To request master control at a remote CDU:
Press the
MASTER
key.
Master control is transferred and
the mode indication changes from

Note Master control can only be requested from a CDU which is currently

CDU.
Any remote CDU may request master control at any time, i.e. control
requests cannot be refused by the current master CDU.
