NOTES
* We cannot supply PWB with component parts in prin-
ciple. When a circuit on PWB has failure, please repair
it by component parts base. Parts which are not men-
tioned in service manual are not supplied.
* Prevent damage caused by static electricity when re-
pairing the pick-up.
The pattern of the pick-up is short-circuiting for preven-
tion. Remove the soldering with a solder iron whose in-
sulation resistance is larger than 10M ohm(DC500V) after
complete connection to the main PWB. For repair table
shall use copper or conductive sheet (with impedance is
lower to 100M ohm from 1M ohm) such as a sheet.
Be sure to put on a wrist-strap for prevent electric static's
