BEFORE RETURNING THE AUDIO PRODUCT
(Fire & Shock Hazard)
Before returning the audio product to the user, perform the
following safety checks.
1. Inspect all lead dress to make certain that leads are not
pinched or that hardware is not lodged between the chassis
and other metal parts in the audio product.
2. Inspect all protective devices such as insulating materials,
cabinet, terminal board, adjustment and compartment covers
or shields, mechanical insulators etc.
3. To be sure that no shock hazard exists, check for leakage
current in the following manner.
* Plug the AC line cord directly into a 120 volt AC outlet.
* Using two clip leads, connect a 1.5k ohm, 10 watt resistor
paralleled by a 0.15µF capacitor in series with all exposed
metal cabinet parts and a known earth ground, such as
conduit or electrical ground connected to earth ground.
* Use a VTVM or VOM with 1000 ohm per volt, or higher,
sensitivity to measure the AC voltage drop across the
resistor (See diagram).
* Connect the resistor connection to all exposed metal parts
having a return path to the chassis (antenna, metal cabinet,
screw heads, knobs and control shafts, escutcheon, etc.)
and measure the AC voltage drop across the resistor.
All check must be repeated with the AC line cord plug connection
reversed.
Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp.
AC.) or more is excessive and indicates a potential shock
hazard which must be corrected before returning the audio
product to the owner.

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 without
frequency setting by adjusting personnel when the tuner section is adjusted in the production line.
2. Details of tuner test mode
When the power is turned on by using the "POWER" button while the "FF/FWD" and "MEMORY/SET" buttons are held down
in POWER OFF state, the frequency for adjustment and measurement of destination specified by the AREA terminal is preset
and stored in the preset memory CH. However, Ordinary 1 and Ordinary 2 are set to the designation (destination selected
by SPAN switching operation) set when the test mode is set. (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. However, FUNCTION switching
is invalid.
Since it is necessary to discard the content of preset memory when the tuner test mode is ended, "0000" or "1111" bits are
written in the memory to be checked in case of memory check (in case of initial setting) so that memory abnormality is detected
in case of initial setting so as to ensure memory initialization.
When the tuner test mode is turned on, the following indication lights for one second.
• The TUNER TEST2 mode is set as a result of >> + MEMORY + POWER. -> IF AC is set to OFF in the TEST2 mode, the initial
state is restored.
When POWER is set to OFF, the memory of TEST2 mode is protected.
When the power is turned on again, the ordinary operation is enabled while the data is stored in the
memory (besides TUNER).
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, holding down MEMORY + BASS/TREBLE.
When the following operation buttons are pressed in this sate, the operation is executed as follows.
"POWER".................The test mode is turned off, the power is turned off, and the ordinary standby mode is set.
"FF/FWD".................The pickup slides toward the outer periphery while this button is held down.
"REW/REV"..............The pickup slides toward the inner periphery while this button is held down. However, if PU-IN is on, input
is invalid.
"PLAY" .....................Invalid
"STOP".....................Return to step 1
"FUNCTION"............Shift to step 6
"BAND" ....................Shift to step 7
*If the focus is disturbed, the process returns to step 1.
Other cautions
• TOC IL is not executed in the test mode.
• As for button operations other than those shown above, only the sound volume operation (with JOG) is accepted.
3. Preset frequencies for various destinations (random preset memory)
• The hatched sections of the table are not stored in memory.

7. Key input diagnosis Test Mode (TEST 6)
When the test mode is set, the following indication appears.
This test mode is intended to check whether all the main unit buttons can be detected. Accordingly, in this test mode checking
as to whether the "POWER" button was pressed after all the buttons shown below were pressed is performed. If the result is
OK, OK is indicated. Even any one of keys was not pressed, an error is indicated. In case of OK termination or error termination
exit from this mode occurs when the "POWER" button is pressed next time, and the standby mode is set.
All the models using this microcomputer do not use the same buttons. Some models do not have specific buttons. Accordingly,
the input of the following buttons is detected by using the combination of buttons to be pressed together when this mode is turned
on.
The button pressing order is not specified. Checking as to whether all the buttons were pressed is executed.
1. In case of "FF/FWD" + "REC PAUSE"
Since RDS and SURROUND are not provided, the following 11 buttons are detected as all buttons.
PLAY, JOG MODE, BAND, BASS/TREBLE, FUNCTION, MEMORY/SET, REC PAUSE, REW, FF, STOP, CLOCK/TIMER/
SLEEP
The OK/NG indication of test result is as follows.
4. Electronic volume Test Mode (TEST 3)
When the test mode is set, the following indication lights for one second.
When this mode is set, BASS/TREBLE is set to 0 (0 dB) and SURROUND mode is set to off, and start-up function is set to CD
when volume is -14 dB (STEP 17). The button operations in the test mode are the same as those of ordinary operation excepting
sound volume UP/DOWN.
(1) The indication is the same as that of ordinary operation excepting test mode setting.
(2) The sound volume control with the sound volume UP/DOWN button is only the following 3 steps unlike the ordinary state.
Volume- ∞ (STEP 0) <-> Volume-14 dB (STEP 23) <-> Volume-0 (STEP 30)
(3) BASS/TREBLE and SURROUND are switched when button operation is performed.
The current time and timer time are set in the following procedure to perform the timer playback.
1.Set the current time to 1:00, set the timer to ON time 1:02, set the function to Tape, and set volume STEP 8. One minute is counted
as one second, and the timer playback operation is performed. The fade-in (when playback is started) is executed at a rate of
one step for 0.5 sec. After completion of fade-in the fade-out is executed at a rate of one step for 0.5 sec (WAIT 1 sec inserted).
After completion of fade-out the power is turned off (after WAIT 1 sec), and the mode is changed to the standby mode.
The indication during operation is the same as that of ordinary timer operation.
6. LCD Test Mode (TEST 5)
When the LCD test mode is set, all the LCD segments are lighted. After that the indication is changed as follows according to
the "PLAY" button input.
Lighting of all segments Lighting of odd segments Lighting of even segments
5. Timer test Mode (TEST 4)
