SERVICE TEST PROGRAM
The microprocessor in the digital operating part contains
a test program which can be divided into the following
sections:
1. Display test
2. Keyboard test
3. ROM code
4. RAM test
1. Display test
The Display test program can be called up by
pressing at the same time keys "DECK A" and "DECK
B" from the basic test program. The following LEDS
will light up:
LED: DECK A
REC
CD SYNCHRO
1 3
DIR
<
HlGH
2. Key test
When a function key is pressed, an LED or
combination of LEDs will light up on the display (see
table 1).
3. ROM code
By pressing keys "Dubbing NORMAL" and "DECK A
at the same time, the ROM code becomes visible.
This is indicated by an LED combination (see table 2).
4. RAM test
The RAM test can be called up by pressing the keys
"DIRECTION" and "STOP" at the same time. If the
result of the RAM test is positive, the "DECK A" and
"DECK B" LEDs will start to flash. If a defect is found
in a RAM cell, the unit will exit from the test program
and return to Normal mode.

The unit can be set in test mode by pressing keys "DECK
A" and "DECK B" at the same time and holding them
depressed and then switching on the power switch.
As long as the keys "DECK A" and "DECK B" are
depressed, you are in the test mode "Display test" (see
section 1). After the two keys are released, you are in the
basic test program.
The following LEDs will now be lit: DECK B,

Note:
The test program does not start up if the
microprocessor is defective or a number of basic
conditions are not fulfilled.
Thus, in the case of a supposed defect in the operating
part, first check the supply voltage, function keys DECK
A and DECK B, the clock signal and the reset pulse.

Note:
The RAM test should be carried out last
because no other test can be called up from the RAM
