TEST MODE
The test mode applied to this microcomputer has three modes,
namely the ordinary test mode for adjustment or measurement,
the aging test mode, and the self-diagnosis test mode for self-
judgment in case of final product inspection.

For obtaining each test mode, press the ON/STAND-BY
button, while keeping pressing the following two buttons in
the ordinary stand-by mode (power off ). In this case, the
main unit buttons are valid. When turning the ON/STAND-
BY on with remote control buttons, test modes are not
obtained.

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.
• 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).
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.
