Procedure:
1. Press the 

[POWER]

 button while shorting the BP (TEST

MODE) on the PANEL board, and turn on the power so that
the following operations will be executed automatically.

1

Grid of all segments lights up sequentially starting from 1G
to 16G.

2

 The vertical line (total 5 lines) of all grids lights up sequen-

tially in the range of 3G to 16 G starting from the left.

3

 The horizontal line of (total 7 lines) of all grids lights up

sequentially in the range of 3G to 16G starting from the top.

4

 Grids from 5G to 6G go off.

2. With the machine in the status that is set in step 1-4, press

any on the remote commander. The grids 1G and 2G go off
and then the machine enters the key check standby state. (When
the 

[OPEN/CLOSE]

 key or the 

[  ]

 key is pressed, the recep-

tion check is canceled.)

3. After the key check is completed, turn JOG clockwise to turn

on the calendar segments sequentially. When the segment “20”
is confirmed, turn JOG counter-clockwise that turns off the
calendar segment. When the segment “1” is confirmed, this is
the end of check.

4. After all the checks are completed, confirm to see that the dis-

play  “!%%TEST-END!!%” appears. The message indicates
that the check is ended normally.

5. Press the 

[POWER]

 button to turn off the main power and

disconnect the power plug from the wall outlet.
