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

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
