Diagnostics Tests
Motor Sensor Test
The “Motor” Sensor test can help you determine
whether there may be a problem with the Baby Lock
Crown Jewel II motor. Slowly rotating the handwheel
should result in a pulsing audible “beep.” If you get a
constant solid “beep” or no “beep” at all, this indicates
a failed test and the machine should be inspected by an
authorized Baby Lock retailer. (Figure 37)
Press the “Main” button to return to the “Regulated” or
“Manual” menu screen or the “Back” button to return
to the “More” menu screen.
Needle Sensor Test
The Needle Sensor test will indicate whether the needle
position sensor is functioning properly. Rotating the
handwheel should result in a “beep” for half of a stitch
cycle followed by no “beep” for the other half.
(Figure 38)
If you hear a constant beep or no beep at all for a full
360° rotation of the handwheel, this indicates a failed
test and the machine should be inspected by an au-
thorized Baby Lock retailer.
Press the “Main” button to return to the “Regulated” or
“Manual” menu screen or the “Back” button to return
to the “More” menu screen.
