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.
