6.4 Changing halogen cold-light lamp
Before opening the lamp slot, switch of the unit !
The lamp and the housing of the cold-light module
are very hot after failure !
Allow them to cool down!
The lamps of the cold light system are integrated in the
function column. The light module can completely be
extracted by opening the two locking screws. Thus, the
lamps can easily be replaced.
The lamps are horizontally inserted in a socket from which
they can be removed by pulling to the centre of the module.

foil remains on the lamp until it is inserted in the
socket)!
Prior to changing, check on which light exit the lamp
has to be replaced !
Do not look directly into the light exits !
Insert the spare lamp in the socket.
Then remove the foil on the lamp.
Make sure that the lamp is inserted in horizontal
position !
If lamps are inserted in inclined position or not up to
the stop, the light performance is considerably
diminished.
Slide the light module in up to its stop.
Fix the light module again with the two locking screws.
