Wrap insulating tape.

Short-circuit between the A (positive) and the B (negative) terminals
on the ST-79 board with the short jig about 10 seconds.

Make sure that the flat cable and flexible board are not cracked of
bent at the terminal.
Do not insert the cable insufficiently nor crookedly.

Cut and remove the part of gilt 
which comes off at the point.
(Be careful or some 
pieces of gilt may be left inside) 

When remove a connector, don’t pull at wire of connector.
It is possible that a wire is snapped.

When installing a connector, don’t press down at wire of connector.
It is possible that a wire is snapped.

The charging capacitor (C601) of the SL-59 flexible board is charged
up to the maximum 300 V potential.
There is a danger of electric shock by this high voltage when the
capacitor is handled by hand.  The electric shock is caused by the
charged voltage which is kept without discharging when the main
power of the unit is simply turned off.  Therefore, the remaining
voltage must be discharged as described below.

To preparing the short jig, a small clip is attached to each end of a
resistor of 1 k

Ω /1 W (1-215-869-11).

Wrap insulating tape fully around the leads of the resistor to prevent
electrical shock.
