OPERATION NOTES
Make sure that the conductive side of a flexible board does not have any stain or foreign materials.
Do not touch the conductive side of flexible boards with bare hands.
Plug in a flexible board straight, fully into the connector until it reaches the end inside. (Fig. 1, Fig. 2, Fig. 3)

• Make sure that the flat cable and flexible board are not cracked
or bent at the contact end.
• Do not apply excessive force to the gilded flexible board.

The charging capacitor is charged up to the maximum 310 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 dis-
charging when the main power of the unit is simply turned
off. Therefore, the remaining voltage must be discharged as
described below.

Preparing the Short Jig
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.
