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.
