@) Starting the main unit test mode
When plug the power cord in the outlet while depress-
ing the "TUNING DOWN" key, the test mode is entered
which uses the main unit keys. At this time the follow-
ing three actions occur:
e¢ The power comes ON automatically.
¢ The fluorescent display and all LEDs illuminate.
Ail conditions except POWER ON/OFF are initialized.
The all-illuminated state is cleared by pressing any main
unit key. Also, any conditions changed during test mode
are reinitialized when the test mode is cleared (by turn-
ing the AC power supply OFF).
(2) Automatic motor VR UP/DOWN (AMP)
Operating the "TAPE 2" key actuates the motor VR as
follows: 16 seconds UP > 16 seconds DOWN ~ STOP.
Accordingly, "TAPE 2 MONITOR" switching cannot be
done during the main unit test mode.
(3) Mute signal output (AMP)
No Selector MUTE (MUTE 1) control regulation is done
whatsever.
(4) 0~9, +10 testmode (TUNER)
a) When the +10 key is not operated, channels 1
through 9 (1~9 keys) and channel 10 (0 key) can
be called.
b) When the +10 key is operated once, channels 11
through 19 (1 ~9 keys) and channel 20 (0 key) can
be called.
c) When the + 10 key is operated once more, the con-
dition returns to that of a) above: ''when the +10
key is not operated."'
(©) Operations that can only be done by remote control
a) AMP system: NONE
b) TUNER system: NONE
c) SURROUND system
"P. CH CALL" key: Same operation as the ''CENTER
MODE" key.
"DIRECT" key: Same operation as "TEST TONE" key.
* Naturally enugh, "P. CH CALL" "DIRECT'"' opera-
tion cannot be carried out.
© During the test mode, because there is no 4/8
switching input status display, the fluorescent
"SPEAKERS" display is substituted instead.
(4/8 = Light on/Light off) As a result, please be careful
concerning illumination of "SPEAKERS" during the test
mode.
@ Cancellating the main unit test mode
When the power cord unplug in the AC outlet during
the main unit test mode, the test mode is cancelled and
the initial condition restored.
