Operation of the Test Mode
1. When the "EJECT" key is pressed, cassette mechanism switch
check mode is entered and the DISPLAY Part displays the
following.
REV REC SW
ON: REV recording
OFF:
FWD REC SW
ON: FWD recording possible
OFF:
TAPE TYPE
NORMAL
2. When the "REC PAUSE" key is pressed, the mode for opening
of REC PLAY is reached, automatic recording and playback
mode is reached and the following operation is performed.
1 FUNCTION is set to AUX.
2 FWD recording is performed for 4 sec.
3 RVS recording is performed for 4 sec.
4 FWD playback is performed for 4 sec. (Function becomes
TAPE), and the unit stops.
5 RVS playback is performed for 4 sec.
6 STOP.
7 REC PAUSE . ( Direction becomes FWD )
LINE MUTE opens in REC condition.
3. "DOLBY" ON/OFF check mode is made with the remote
control " STOP" key.
4. The remote control the keys "PLAY", "FF", "RWD", "STOP",
and "REC" operate normally and LIN MUTE opens in REC/
REC PAUSE condition.
5. When abnormal operation is detected, the corresponding code
will be displayed on the DISPLAY Part.
01 ........ The tape does not loading/eject-error.
02 ........ The deck mechanism assist does not setup
position.

Error Code
6.2 SINGLE OPERATION METHOD
Operation of preparation
Connect part A of the MAIN ASSY [W156 (GND) and
W134 (GNDPB)], short-circuit the TEST MODE JP [W137
GNDC) and W138 (TEST)] (pin 30 of the microcomputer
connected to GND), and supply DC power to part [W155
(9 V), W154(-10 V) and W156 (GND)]. (Refer to Fig. 6-1.)
In case of single connect load
In case of adjustment as a single unit, connect a 27 kΩ load
resistor to pins W149(PBR) and W150(PBL) of (MAIN
ASSY ). (Refer to Fig. 6-4.)
In case of input signal
In case of adjustment as a single unit, enter the signal at
W147(REC_L) and W151(REC_R) of MAIN ASSY. At this
time, connect an output buffer amplifier to the oscillator, and
then connect a series resistor(180 Ω) after the impedance
hasbecome sufficiently low. (For MPX filter impedance
matching) (Refer to Fig. 6-4.)
In case of Fuction
Connect part B of the ILLUMI ASSY[ "REW"(W177) and
"FF"(W175) circuit the TEST JUMPER [W176 GNDC] .
