Troubleshooting
If trouble occurs
When this product is subjected to strong external interference (mechanical shock, excessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is operated incorrectly, it may malfunction. If such a problem occurs, do the following: 1 Set the unit to the stand-by mode and turn the power on again. 2 If the unit is not restored in step 1, unplug and plug in the unit, and then turn the power on. 3 If neither step 1 nor 2 restores the unit, do the following: Press the ON/STAND-BY button to enter the power stand-by mode. Unplug the AC power lead from the AC INPUT socket on the unit. Whilst pressing down the MEMORY/SET button and the / button, plug the AC power lead into the AC INPUT socket on the unit.

When the CD does not function
When the CD section does not operate when the objective lens of the optical pickup is dirty, this section may not operate. Clean the objective lens, and check the playback operation. When this section does not operate even after the above step is taken,check the following items. Remove the cabinet and follow the troubleshooting instructions. "Track skipping and/or no TOC (Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickup lens. Before attempting any adjustment make certain that the lens is clean. If not, clean it as mentioned below." Turn off the power, and wipe the lens softly using a cleaning paper moistened with commercially available cleaning solution so as not to damage it. Be careful not to touch the lens with bare hands. Dust gradually accumulates on the objective lens during use, and it may degrade performance. To avoid this problem, use a cleaning disc designed for CD optical pickup lenses. HOW TO USE 1. Using the brush in the cleaner cap, apply 1 or 2 drops of the cleaning fluid to the brush on the CD cleaner disc which has the mark next to it. 2. Place the CD cleaner disc onto the CD disc tray with the brush side down, then press the play button. 3. You will hear music for about 20 seconds and the CD player will automatically stop. If it continues to turn, press the stop button. CAUTION The CD lens cleaner should be effective for 30 - 50 operations, however if the brushes become worn out earlier then please replace the cleaner disc. If the CD cleaner brushes become very wet then wipe off any excess fluid with a soft cloth. Do not drink the cleaner fluid or allow it to come in contact with the eyes. In the event of this happening then drink and / or rinse with clean water and seek medical advice. The CD cleaner disc must not be used on car CD player or on computer CD ROM drives. All rights reserved. Unauthorized duplicating, broadcasting and renting product is prohibited by law.
Make sure that the disc is normal, and set the CD TEST MODE (STEP 1).

3. Tuner Test Mode (TEST 2) 1. Outline of tuner (radio) test mode The tuner test mode is intended to store the adjustment and measurement frequencies in the preset memory CH. When adjusting the tuner section in the production line, adjusting personnel are not required to set frequency. 2. Details of tuner test mode Press the "REW/PRESET DOWN" and "CD PLAY" buttons in POWER OFF state and turn on the power by the use of "ON/ STAND-BY" button to preset and store frequency for adjustment and measurement of destination specified by the AREA terminal in the preset memory CH. However, Ordinary 1 and Ordinary 2 are stored in the destinations (selected by SPAN switching operation) when the test mode is obtained. ("FF " + "MEMORY/SET" KEY SPAN CHANGE) (As for frequencies to be preset and stored for each destination, refer to item 3.) The tuner test mode is started from preset No.1. The operations of test mode are identical with the ordinary operations of TUNER function. FUNCTION switching is invalid. It is necessary to discard the content of preset memory when the tuner test mode is ended; be sure to write "0000" or "1111" bits in the memory to be checked for judging memory error at initial setting and to initialize memory. When the tuner test mode is obtained, the following display lights for one second.
4. Electronic volume Test Mode (TEST 3) When this test mode is obtained, the following display lights for one second.
In this mode, volume is -14 dB (STEP28), BASS/TREBLE is set to 0 (0 dB) and SURROUND mode to OFF, and start-up function to CD, respectively. The button operations in the test mode are the same as those of ordinary operation except volume UP/ DOWN. (1) The display is the same as that of ordinary operation except test mode setting. (2) Unlike the ordinary state, the volume is controlled with the volume UP/DOWN button in accordance with the following three steps. Volume-
(STEP 0) <-> Volume-14 dB (STEP 23) <-> Volume-0 (STEP 30)
(3) BASS/TREBLE and SURROUND are switched when button is pressed.. 5. Timer test Mode (TEST 4) When this test mode is obtained, the following display lights for one second.
TEST MODE
Set the current time and timer time according to the following procedure to reproduce the timer.
· The TUNER TEST2 mode is obtained with >> + MEMORY + ON/STAND-BY. ->Turn off AC in the TEST2 mode to restore the initial state.
Turn off POWER to protect the memory of TEST2 mode. Turn off POWER again to obtain the ordinary operation while the data is stored in the memory (besides TUNER).
1.Set the current time to 1:00, the timer to ON time 1:05, the function to CD, and volume to STEP 12, respectively. One minute is counted as one second, and the timer is reproduced. The fade-in (when playback is started) is executed at a rate of one step for 1 sec. After completion of fade-in, the fade-out is executed at a rate of one step for 1 sec (WAIT 1 sec inserted). After completion of fade-out, the power is turned off (after WAIT 1 sec), and the mode is shifted to the standby. The display during operation is the same as that of ordinary timer operation. 6. LCD Test Mode (TEST 5) When the LCD test mode is obtained, all the LCD segments are lighted. Then pressing the "PLAY" button switches display as below. Lighting of all segments Lighting of odd segments Lighting of even segments
If AC OFF state is maintained in this state for about 1/2 day, start is executed in the initial state. · To clear the whole memory, insert the AC cord, pressing MEMORY + CD PLAY. 3.

This test mode is intended to check whether all the main unit buttons can be detected. Accordingly, in this test mode, it is checked whether the "ON/STAND-BY" button was pressed after all the buttons shown below were pressed. If the result is OK, OK is displayed. If any one of keys was not pressed, an error is displayed. In both cases of OK termination or error termination, the mode is shifted to the standby mode if the "ON/STAND-BY" button is pressed subsequently. All models using this type of microcomputer are not always provided with the same buttons. Since the buttons used are different depending on models, types of buttons to be used are determined by whether RDS, SURROUND, and an electric lid are available at the initial setting by MODEL port. The order of buttons to be pressed is not determined. Accordingly, it is checked whether all buttons have been pressed.
