5.4 Warming up
By means of the special function "warming up" a determined speed can be set without gear shifting.
This function is necessary to warm up the engines.
To activate "warming up", the key must be pushed at the active control station and, at the same time,
the lever moved in ahead or astern. Then the key may be depressed again. To turn the function off,
the lever must be moved in neutral again. When doing so, the key must not be pushed.
When the function "warming up" is active, the
command lamp flashes.

Command lamp flashes
Note for twin engines: The function "warming up" can be activated and deactivated of both sides
separately. The command lamp is assigned to the respective lever.
5.5 Increased idle speed
By the special function "increased idle speed" a higher idle speed can be selected. This function will
be necessary if the driving engine shall operate a bow thruster in addition and the normal idle speed
engine performance is not sufficient therefore.
To turn this function on and off, the key on the active control station must be pushed. The function can
be switched on in neutral only and switched off at any time.
!
The function "increased idle speed" is available only if it has been set up before
(see chapter 4.3. speed). When this function has been entered, "synchronizing"
cannot be deactivated again.
5.6 Synchronising
If, for twin engine systems, the positions of the port and starboard levers on the active control head
deviate less than 10% from each other in the range of "ahead", the same nominal value (of the port
lever) will be set.
If "Synchronising" is active, this will be indicated
by the lamp "Synchro".

To switch off this function, the key on the active control station must be pushed.
The function will activate again as soon as the levers deviate 10% maximum from each other again at
another position.
Note for „increased idle speed“: "Synchronizing" cannot be switched off if the function "increased idle
speed" is active.
!
The function "Synchronization" is available only if it has been set up before (see
chapter 4.2 "control head", synchronizing).
