2. When entering the test mode, the manufacture code of the
Flash ROM (4M) is read and when it is normal, FROMCHK
of the 100th terminal (Panel
µ
-com) repeats Hi
→
Low
→
Hi · · ·. If the reading is abnormal, “Low” is output.
If the manufacture code is normal, by pressing [
] key for
less than 1 second, the connection checks on all terminal
is started. If the connections are normal, the FROMCHK
terminal stops the Hi
→
Low
→
Hi · · · repeating and out-
puts “Hi”. If the reading is abnormal, “Low” is output.
3. With all lights turned on and by pressing [AM] key for at
least 1 second, the data on the Flash ROM (4M) is initial-
ized. While erasing the data, “Data_Erase....” is displayed.
Note :
Do not touch any key white this is in progress.
When erasing is complete, “Erase_OK!!” is displayed.
If “Erase_NG!!!!!!” is displayed, it was not possible to erase
the data on the Flash ROM (4M).
In this case, pressing [AM] key for at least 1 second again.
If it is the same, then there is an abnormality with the Flash
ROM.

• At Power ON, “CODE_OFF”, “CODE_ON” displays will not
be made.
• When sourcing STANDBY, by pressing [AUTO] or [TI] key
for less than 1 second, GREEN/RED of the key illumination
is switched.
When doing this, the triangle illumination GREEN/RED is
switched along with the key illumination.
• When staring up in the test mode, LINE MUTE prohibition
time is set to 1 second instead of 10 seconds.
• While in the test mode, even when a DC offset error is de-
tected, the detection information will not be written to the
• While in the test mode, even after an elapse of pre-set time,
the backup memory items will not be written to the E2PROM.
• Information Clear mode for Test Mode, backup/installer
memory, and CD mechanism error log.
In the DC offset error detection information clear mode,
DEMO mode operation will not be conducted.
Also, in the above mode, the menu of the STANDBY source
will not display DEMO ON/OFF switching items.
• While in the test mode, and at the same time, PM_DET of
the 60th terminal (System
µ
-com) is H, the following will
apply to the EJECT key, regardless of whether a disc is in
the unit or not.
Panel full OPEN/CLOSE is conducted with a push for less
than 1 second. (Protection time : 3 seconds)
As far as this item is concerned, eject will be achieved by
for at least 1 second push on the EJECT key.

Clearing backup memory and installer memory
data (Clearing E2PROM data)
1. By pressing [
] (NEXT) key and [ATT] key simultaneously,
reset and start the unit. This will start the initialization pro-
cesses for backup and installer memory data and the error
log information of the CD mechanism.
2. When initialization is complete, the following display will be

no backup memory items will be written to the E2PROM.
4. This mode is released by resetting. (What was on the last
