Precautions
To prevent damage caused by static electricity, the following procedures for grounding is requir or repairing
the unit.
Shorting tab
Desolder here
Pickup
[Note] Remove the connection after installed.
1. Wrist-Strap
for grounding
1MΩ
1MΩ
2. Conductive Sheet
Pickup
1. Grounding for the human body
Be sure to put on a wrist-strap for grounding (with impedance lower than 106 Ω) whose other end is
grounded. The strap works to drain away the static electricity build-up on the human body.
2. Grounding for the work table
Be sure to lay on the table a conductive sheet (with impedance lower than 106 Ω) such as a sheet of
copper which is grounded.
3. As static electricity build-up on clothes is not drainded away, be careful not to let your clothes touch the
unit.
4. The short-pad on the pick-up PCB of a spare part is short-circuited for protection during shipment. To
open the short circuit, remove the soldering quickly with a soldering iron whose insulation resistance is
larger than 10MΩ after connection to a suitable APC circuit.
Equipment Required
* Multi Meter
* Oscilloscope
* Compact Disc
* Dummy Load 10 kΩ
