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)
OK
(The flexible board was plugged in straight (The flexible board was plugged in
and completely) crooked.)

• 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 proper way to disconnect a connector is to grab the con-
nector instead of the wires. If you pull on the wires, they might
be broken.

pieces of gilt may be left inside)
DISCHARGING OF THE CHARGING CAPACITOR
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.

Board Preparing the Short Jig
To preparing the short jig, a small clip is attached to each end
of a resistor of 1 kΩ /1 W (1-215-869-11).
Wrap insulating tape fully around the leads of the resistor to
Connector
prevent electrical shock.

Discharging the Capacitor
Short-circuit between two points with
the short jig about 10 seconds.
