Press and hold: To clear entire CD information (Press and
hold for 2 seconds)
● Initializing AUDIO-related setting value
Press the [
] key briefl y in the STANDBY source and
reset the AUDIO setting value to the test mode default
value.
● Flash ROM check (X16-398 IC1)
1. After entering the test mode, read the manufacture code
of the Flash ROM, and the FROMCHK terminal of the
IC4-pin 100 repeats the "Hi→Low→Hi · · · · " under the
normal condition.
Output "Low" under the abnormal condition.
When the manufacture code is normal, press [AM] key
briefl y to start checking the connection at all the terminals.
When the connection is normal, terminate the repetition
of "Hi→Low→Hi · · · · " at the FROMCHK terminal, and
output "Hi".
When the connection is not normal, output "Low".
2. If the [AM] key is pressed and held for 2 seconds while all
lights are on, Flash ROM data is initialized.
While the deletion is executed, "Data_Erase...." is
displayed.
(Note) Do not touch anything while this is being displayed.
At the completion of the deletion, "Erase_OK!!" is
displayed.
If the "Erase_NG!!!!!!" is displayed, it indicates that the
data in Flash ROM could not be deleted due to some
reason.
If the same message is displayed after repeating the
process by pressing and holding [AM] key, it indicates the
error in Flash ROM.
● Static RAM Check (X16-398 IC12)
(Regardless of the test mode,) the manufacture code is
read out from the Static RAM after the Power ON, and "Hi"
is output at the SRAMCHK terminal (pin 92) of the IC4
when the code is normal.
When the code is abnormal, "Low" is output.
TEST MODE
● Other
• When Power ON, do not display "CODE_NG", "CODE_
OFF" and "CODE_ON".
• When started in the test mode, duration of prohibiting
MAX 99 (times)
LINE MUTE shall be changed from 10 seconds to 1
second.
• When in the test mode, do not write security code by
security jig.
• When in the test mode, serial number is not written with a
serial-number-writing jig.
• When in the test mode, when DC error detection is run,
the detection information is not written into the E2PROM.
• When in the test mode, even if the specified time has
passed, back-up memory items are not written into
E2PROM.
• DEMO mode shall not be operated while in the test mode,
Backup/Installer Memory & CD Mechanism Information
& Service Information & DC Error Detection Information
Clear Mode, or DC Error Detection Information Clear
Mode.
Also, do not display DEMO ON/OFF option items in the
MENU in STANDBY source in the above modes.
• In the test mode and when the PM_DET terminal is
"H", the panel is fully opened or closed by pressing the
[EJECT] key briefl y regardless of the disk is inserted or
not. (Protection time is 3 seconds.) At this time, press and
hold the [EJECT] key for 1 second to eject the disk.
● Clearing DC error detection information
(E2PROM(F/E) data clearing)
1. Press and hold [ATT] and [AUD] keys and reset-start
to go into the DC error display mode. (While "– – – –" is
being displayed, power can be ON for 30 minutes.)
2. While in STANDBY source, the current DC error detection
condition is displayed.
