●How to enter the test mode
• In order to enter the test mode, while pressing down [ATT]
+ [WOW] keys simultaneously, press [SRC] key.
●Test mode conditions
• The test mode starts up when STANDBY source is selected.
• The volume value is -10dB. (30 on the display)
• Beep prohibited.
• All lights displayed.
• WOW : OFF
• EQ : Natural
• SPEANA : PEAK HOLD
●Test Mode (Display)
• Since the display has many segments, it is possible to con-
firm on the bridges with other segments. (Only when the
source is set to STANDBY)
[], [ ], [FM], [AM] keys are used to switch the display
segments.
[], [ ] keys are used to switch the grids.(Forward and
Reverse)
[FM], [AM] keys are used to switch the segments. (Forward
and Reverse)
●Test mode
(Display of DC offset detection presence/absence)
• When in this mode, the mode for “Display of DC offset de-
tection presence/absence” will be added in the MENU items
at the time whenTest Mode Standby is the source. This will
make itpossibletoconfirm results withpresence-or-absence
detection.
MENU selection :DIMMER adjustment →…→(NAVI ATT
ON/OFF) → (CODE STBY) → Display of DC offset detec-
tion presence/absence.
• Display
DC Offset detected : DC Err
DC Offset not detected : DC OK
*The detection information in the EEPROM can be forcibly
cleared by pressing [ ] or [ ] key for more than two
seconds while the DC Offset detection (DC Err) is being
displayed.In this case, the display will be for DC Offset not
detected. (DC OK).

●Test mode (Accumulated elapse time display)
• When in this mode, the mode for “Accumulated ElapseTime
Display” will be added in the MENU items at the time when
Test Mode Standby is the source. This will make it possible
to confirm on the accumulated elapse time.
MENU selection :DIMMER adjustment →…→(NAVI ATT
ON/OFF) →(CODE STBY) →Display of DC offset detec-
tion presence/absence →Accumulated Elapse Time Dis-
play.
*By pressing [ ] or [ ] key for during Accumulated
ElapseTime Display, the sources for the accumulation can
be switched.
MD TYPE MODEL (Repeating sequence : MD accumula-
tion time →CD accumulation time →MD accumulation time)
TAPE TYPE MODEL (Repeating sequence :TAPE accu-
mulation time →CD accumulation time →TAPE accumu-
lation time)
●Releasing the test mode
• The Test Mode is released by the following sequence : Re-
set, ACC OFF and ON, Power OFF and ON. Also, by ACC
OFF and POWER OFF, the Source of Tuner and Audio will
go into the initial conditions.
●Forced clearing of DC offset detection
• Regardless of the Test Mode, when power is turned on by
[SRC] key while depressing the following keys. This will be
the forced clearing of DC Err condition in the EEPOM. This
will clear the data in the EEPROM even in the case where
there is no error data.
• Key Operation
Press the [SRC] key while pressing the [DISP] and [EQ]
key at the same time.
●How to delete registered security codes
• After resetting and entering the test mode again, in the
screen for entering the security code, continue depressing
[#6] key, while depressing [#1] key. This will result in dis-
play of the character “C”on the right side of the code input
screen.
Then, using [1], [2], [3] and [4] keys of the remote control-
ler, input “KCAR”. The registered code will be deleted by
confirming the input with [S.A] key.

CAUTION:Forcontinuedsafety,
replace safety critical compo-
nents only with manufacturer’s
recommended parts (refer to
parts list).
Indicates safety critical com-
ponents. To reduce the risk of
electric shock, leakage-current
or resistance measurements
shall be carried out (exposed
parts are acceptably insulated
from the supply circuit) before
the appliance is returned to the
customer.
•DC voltages are as measured
with a high impedance volt-
meter. Values may vary
slightly due to variations be-
tween individual instruments
or/and units.
