button to select the BAND “AM”.
3. Press ?/1button to turn the set OFF.
4. Press TUNER/BAND and ?/1buttons simultaneously, and
the display of fluorescent indicator tube changes to “AM 9 k
STEP”or “AM10 k STEP”,and thus thechannelstep is changed
over.
[Cold Reset]
•The cold reset clears all data including preset data stored in the
RAM to initial conditions. Execute this mode when returning
the set to the customer.
Procedure:
1. Press three buttons x, GROOVE , and ?/1simultaneously.
2. The fluorescent indicator tube displays “COLD RESET” and
the set is reset.
[Aging Mode]
This mode can be used for operation check of CD section and tape
deck section.
•If an error occurred:
The aging operation stops and is displayed status.
•If no error occurs:
The aging operation continues repeatedly.
1. Operating method of Aging Mode
Turn on the main power and select “CD” of the function.
1) Set three discs in tray. Select ALL DISCS, and REPEAT OFF.
2) Load the tapes recording use into both decks.
3) Press three buttons x, GAME EQ , and
DISC SKIP/EX-CHANGE simultaneously.
4) Aging operations of CD and tape are started at the same time.
5) To exit the aging mode, perform [Cold Reset].
2. Aging mode in CD section
1) Operation during aging mode
•In the agining mode ,the program is excuted in the following
sequence.
(1) The disc tray opens and closes.
(2) The disc tray turns to select a disc 3.
(3) The pickup accesses to the first track, and plays 3 seconds.
(4) The pickup accesses to the last track, and plays 3 seconds.
(5) The disc tray opens and closes.
(6) The disc tray turns to select a disc 1.
(7) The same operation starts like step (3).
(8) After a disc 1 aging operation, a disc 2 is selected.
(9) When an aging operation of a disc 3 is completed, the display
“AGING ∗∗∗∗” value increases.
(10) If no error occurs, the aging operation continues repeatedly.

FM Tuned Level Adjustment
Procedure:
1. Supplya 98 MHzsignalat 28dBfrom theANTENNA terminal.
2. Tune the set to 98 MHz.
3. Adjust RV101 to the point (moment) when the TUNED
indicator will change from going off to going on.
Adjustment Location: MAIN board
