5. Power Out connector – power for TFT Screen, labeled 'OUT 2'
It is possible to connect and power 2 TFT Screens using t e 12V Regulator connectors 'OUT 1' and
'OUT 2'.

Step 1 – Prepare the Playfield
Remove t e lock down bar and play field glass. Remove all of t e balls from t e ball troug .
Lift t e playfield forwards so t at it rests on t e lock down bar mec anism, as s own in figure 4.

Using 2 cable ties, fix t e cables coming from t e back box to t e wiring loom conduit as s own in
figure 9.
Figure 9 – Cable fixing
Fixing t e cables in t is way will allow t e back box to be folded wit out straining t e cables to t e
DMD Extender.
Now close t e back box lig t door and replace t e translite.

Step 6 – Mount the TFT Screen
Select w ic side t e of t e apron to install t e TFT Screen – it can be mounted in eit er of t e
