2.6 Transducers
The transducers are a ‘sealed unit’. However, it is possible to gain access to the 2 MHz assembly by
removing the two blanking grommets and M3 countersink screws. Removing the screws will allow the
assembly to be split along its length. Gently prise the assembly apart.
The circuit board is bonded and keyed to the faceplate assembly using a high strength cyno-acrylic
adhesive.
Circuit board removal is carried out by carefully breaking the bond and de-soldering the crystal wires and
retractile cable connections (see diagram below).
