8 Troubleshooting
109
After checking/upgrading the bus master firmware, and you still suspect a defective bus master board,
first try plugging the transducers into another monitor. If the transducers work properly with the other
monitor, then exchange the bus master board.
In the case of the INOPs
FHR1 Equip Malf
,
FHR2 Equip Malf
, and
FHR3 Equip Malf
, when there are two or
more ultrasound transducers attached to the monitor, identify the transducer for which the INOP was
issued, using the blue transducer Finder LED. Touching a numeric on the screen turns on the Finder
LED light of the transducer providing the measurement. If you cannot identify the suspected
transducer directly, because the transducer Finder LED does not light up due to a defect, identify the
other functioning transducers by activating their Finder LEDs, thus finding the defective one by a
process of elimination.
