1-1. NOTE FOR REPAIR

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)
1-2. DISCHARGING OF THE BT-015 BOARD'S CHARGING CAPACITOR (C414, 415)
The charging capacitor (C414, 415) of BT-015 is charged up to the
maximum 300 V potential.
There is a danger of electric shock by this high voltage when the
battery 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.

1-2-1. 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 prevent
electrical shock.
SECTION 1

SERVICE NOTE

1 kΩ/1 W
Wrap insulating tape.
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.

1-2-2. Discharging the Capacitor

1. Remove the FR-194 board, and disconnect the harness from
CN404 on the BT-015 board.
2. Connect the short jig to the pin 1 and pin 2 of CN404 on
BT-015 board. Allow ten seconds to discharge the voltage.
