Ultrasound Transducer (Brown)
134 Chapter 11 Replacing Parts
Caution
DO NOT use a screwdriver or similar flat-bladed instrument to separate the
transducer covers as this can damage the seals and cause leakage when the
transducer is re-assembled. Take care when removing the wires as they are
thin and can easily be damaged.
1. Disconnect the transducer from the Monitor.
2. Remove screw covers 1 and 2: press a flat screwdriver into the covers and prise them
out.
Note— When reassembling the transducer, you will need new screw covers as the old
ones cannot be reused.
3. Partially undo screws 3. The two halves of the transducer can now be separated by
pressing down on the screws.
4. Remove the screws 3 and pull the two halves of the cover apart.
5. Disconnect the transducer cable from the crystal board: use a soldering iron to separate
the three cable wires from the board.
Re-assembly is a reversal of the above procedure.
Caution
The use of ultrasound gel that is not approved by Philips may reduce signal
quality and may damage the transducer. This type of damage will not be
covered by warranty.
Note— Older Brown transducers can be repaired but Blue Ultrasound transducers
are sealed units and are factory repairable Only.
