Sensor

The CS LD 1.0 is constantly che-
cking the sensor for the correct
feedback signal. If the sensor is
not fully inserted into the five-pin
socket, or if it is defective, the unit
cannot be properly conditioned
during the "Warm Up" mode. In
the event that the sensor is not
present, not properly connected,
or depleted, the "Check Sensor"
message screen pictured in Fig. 15
will appear.

Additionally, if the unit becomes

an indication that the sensor may
be defective and requires replace-
ment.

Ensure that the unit is powered
OFF.

Remove the old sensor by
pulling the sensor straight off
