TEST MODE

HCD-RG110

[Change-over of AM Tuner Step between 9 kHz and
10 kHz]

•A step of AM channels can be changed o ver between 9 kHz and
10 kHz. (Except AEP/UK models)

Procedure:

1. Press ?/1 button to turn the set ON.

2. Select the function “TUNER”, and press TUNER/BAND

button to select the BAND “AM”.

3. Press ?/1 button to turn the set OFF.

4. Press TUNER/BAND and ?/1 buttons simultaneously, and

the display of fluorescent indicator tube changes to “AM 9 k
STEP” or “ AM 10 k STEP”, and thus the channel step is changed
over.

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.

(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.

2) Error display
