TEST MODE
TEST Mode (Operation Check)
Preform the followingoperation checks using theTESTMode before
starting the repair works.
1. All Keys Operation Check
Connection Method :
1) While pressing the PROGRAM + key and the Á+ key,
ture ON the main power of the regulated power supply (DC
+6V). (Refer to Fig. 1-1.)
2) Remove all hands from pressing the all keys described in above
step 1). The all indications of the LCD must be turned OFF.
(Refer to Fig. 1-2.)
3) When any key of the Operation panel-key block (except
the COMMANDER OFF key), or any key of the LCD touch-
key block is pressed, the signal (carrier 40kHz) as shown in
Fig. 1-3mustbe transmittedin accordancethepressedkey, when
operation of the machine is normal.
4) Press all keys of the Operation panel-key block (except the
COMMANDER OFF key, and of the LCD touch-key block
sequentially. When all keys are pressed, confirm that the long
buzzar sound and all LCD displays are turned off.
NOTE : Be careful that all data in S-RAM is cleared
when the above TEST mode is performed.
•This TEST Mode can be terminated in its middle before testing
all keys by pressing the COMMANDER OFF key. However
the conduction check of the remairing keys cannot be checked.
(S-RAM is not cleared.)
•P-ROM (IC8) is diagnosed to be free from defects when the
steps from 1) to 4) are performed correctly.

2. S-RAM (Learning Function) Operation Check
Connection Method :
1) While pressing the Á – key and the PROGRAM – key,
ture ON the main power of the regulated power supply (DC
+6V). (Refer to Fig. 2-1.)
2) When LEARN only of the LCD display appears, remove
hands from pressing the above mentioned keys. (Refer to Fig.
2-2.)
3) The display appears when the S-RAM is not defective. (The
diaplay NG appears when the S-RAM is defective.) (Refer to
Fig. 2-2.)
4) The display status as described in step 3) continues until any
key is pressed.
•S-RAM (IC3) is diagnosed to be free from defects when the
above steps from 1) to 4) are performed correctly.

1) After turning the switches SW1 and SW2 both ON, turn on the
main power of a frequency counter and that of the regulated
power supply (DC +6V constant voltage).
2) Take reading of frequency counter indication value. This value
is named fA.
3) Turn off the regulated power supply, then turn OFF the switch
SW1. After that, turn back ON the regulated power supply.
4) Take reading of frequency counter value in the same way as
step 2). This value is named fB.
5) Using the frequency values that are measured in steps 2) and
4), calculate the crystal oscillator frequency f1 and the crystal
oscillator frequency f2 using the following equations. Confirm
that the respective specification values are satisfied.
Specification values:
f1 (4 Mz) = fB x 8
f2 (32.768 kHz) = fA x 4
