How to Affix the Piezo Pickup

1.

Swab the location on the circuit board for affixing the piezo element (the 
silkscreened region) with alcohol.

Make sure the area is free of flux, grime, or other soiling.

2.

Make sure the applied alcohol has dried completely.

3.

Peel off the backing of the double-faced adhesive tape on the back of the 
piezo element, and affix the piezo element to the circuit board so that the 
wiring position is aligned with the silkscreened guide on the circuit 
board.

Give attention to the following:

• Do not allow any grime or soiling to adhere to the double-faced adhesive 

tape.

• Press down on the outer periphery of the piezo element to affix it 

securely.

• After affixing the piezo element, make sure that it is not loose at any 

point.

• When pressing down on the piezo element, do not touch the metal 

portion of the piezo element with the bare hand. (Be sure to wear gloves 
or the like.)

• Do not press down on the solder area of the wiring or subject the area to 

stress.

• Do not touch the chip diodes (DA7, DA11, and DA12) or subject them to 

stress.

4.

Apply filament tape (P/No.40122645) to the piezo element from above to 
secure the element to the circuit board.

Use tweezers to avoid transferring oils from the hands.

Once the filament tape has been applied, do not attempt to peel it off and 
reapply it.

5.

Press down on the entire surface of the filament tape and on the outer 
periphery of the piezo element to anchor them in place securely.
