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

When opening the connector's holder in direction A, do not open 
it with excessive force.
When closing the connector's holder, press it evenly while pushing 
a flexible board in direction B.

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

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.
