The illustration shows the 9 kHz interval zones (re- |
|
|
|
|
gions 1 and 3), and the 10 kHz interval zone (re- |
|
|
|
|
gion 2). |
|
|
|
|
This product is not equipped with a span selector. |
|
|
|
|
However, it will be adjusted to 9 kHz AM interval |
|
|
|
|
(50 kHz FM interval) when shipped from the fac- |
|
|
|
|
tory. |
|
|
|
|
Before using the unit, be sure to set it for the AM |
|

TEST MODE
The test mode applied to this microcomputer has three modes, namely ordinary test mode to be used for adjustment or measurement, aging test mode to be used for aging test, and self-diagnosis test mode for self-inspection in case of final product inspection.
1.Turning on the test mode
To turn on the specific test mode, press the POWER button, holding down the following two buttons in the ordinary stand-by mode (power off state). In this case only the main unit button is valid. Even when the POWER of remote control button is set to on, the test mode is not turned on.

[Self-diagnosis test mode]
1.Button input diagnosis test mode (TEST 6)...... REW/REV + Volume Select
2.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 "Volume/JOG Dial Selector" and "Volume Select" 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 TEST 2 mode is set as a result of Volume Select + POWER. -> IF AC is set to OFF in the TEST 2 mode, the initial state is restored.
When POWER is set to OFF, the memory of TEST 2 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 + PLAY.

3.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.
4.Timer test Mode (TEST 4)
When the test mode is set, the following indication lights for one second.
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.
5.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
