(3) Remove the four setscrews and unplug connector CN1 of lead wires.
Among the four setscrews (M2x5), two are for securing the EZJ98 board, the other
two, for securing the APH sensor and EZJ98 board.
(4) With new board, insert the connector into CN1, and tighten the two screws for securing
the APH sensor and the two screws for securing the board.
(5) Solder the coaxial cable to EZJ98 board.
Caution: Do not apply excessive heat: Doing so will melt the resin conductor,
which could cause a short-circuit between the core wire (signal line)
and shielding wire (ground).
(6) Perform the automatic phase gain adjustment.
Caution: If the APH sensor is removed from head base for adjustment, the
insulation tube (5 mm long) may become detached. If it does, be sure to
reattach the insulating tube during reinstallation.
