Removing the FrontĆPanel Assembly
Removal
1. Remove the leftĆend cover ' page 8Ć10.
2. When removing the front panel, lift (but do not remove) the brown or
black clip in the J1 connector before removing the front panel (FP) cable.
You don't need to use any force at all.
Be very careful when disconnecting the front panel connector from the Main
PCA. If the cable is pulled too hard when removing the front panel it can
damage the J1 front panel connector in the Main PCA which means that the
complete electronics module has to be replaced. If you follow the instructions
above, you will not damage the J1 connector:
Remember that the clip must not be removed completely. If removed
completely, the clip will be destroyed.
Installation
1. When installing the front panel, pull the brown or black clip and insert
the cable into the J1 connector. Once the cable is inside the connector,
push the brown or black clip down to hold the cable in place. The
conductive part (metallic part) of the cable must face the Main PCA.
REMEMBER THAT PULLING THE CABLE WITHOUT
RELEASING THE BROWN OR BLACK CLIP WILL
DAMAGE THE CONNECTOR IN WHICH CASE IT WILL
DESTROY THE COMPLETE ELECTRONICS MODULE.
2. Make sure that the Front Panel cable is properly routed by the clips inside
the RightĆend cover and remains underneath the Spittoon at all times. If
the Cable is not routed correctly, the Cutter Assembly can trap the cable
and damage it.
