AMPLIFIER TYPE: SOLID STATE
Other control knobs: Full counterclockwise
SHAPE: OFF
Connect foot switches:
to TIP: A/B - set POLARITY switch on the FS-5L to the Jack
side. FS-5L should light its LED when it is off.
to RING: MANUAL - set POLARITY switch on the FS-5L to
the Jack side. FS-5L should light its LED when it is off.
to CHORUS - set POLARITY switch on the FS-5L to the
side opposite to Jack. FS-5L should light its LED when it is
on.
♦ Function of LEDs in the test mode
The following LEDs express numbers.
The POWER INJECTION LED shows the test results:
OK - lights in green (except in test 1.3)
NG - lights in red
♦ Entering the test mode
While holding down the buttons MANUAL, (MEMORY) A
and B, press the POWER button.
Upon entering the test mode, all LEDs blink.

NG: POWER INJECTION LED lights in red. The defective
device is indicated by the lighting LED as shown in the
table right.
1.4 POWER INJECTION LED
Repeatedly press the WRITE button and verify that the
POWER INJECTION LED changes its color.
Orange →Red →Green
Press the WRITE button to proceed to the next test.
2 Tact switches
The LEDs shown right indicate the test number.
Test No.2
Press the WRITE button when skipping this test. Otherwise,
press the MANUAL button to start the test.
Press the MANUAL, A, B and WRITE buttons in that order
and verify that the LED on the button lights.
Upon pressing the WRITE button, POWER INJECTION
LED should light in green.
Press the WRITE button to proceed to the next test.
3 Foot switches
The LEDs shown right indicate the test number.
Test No.3
Press the WRITE button when skipping this test. Otherwise,
press the MANUAL button to start the test.

Depress the foot switches connected to MANUAL, A/B and
CHORUS sockets in that order. Observe the following LEDs
that should light upon depressing the corresponding foot
switch.
Upon depressing the CHORUS, the POWER INJECTION
LED should light in green to show that the all foot switches
operate correctly.

4.1 Rotate the AMPLIFIER TYPE (rotary switch) knob
from SOLID STATE to TUBE and then to TUBE
DRIVE. Observe the following LEDs that should light
to show the switch position.
When all switch positions are read, the POWER
INJECTION LED lights in green.
Press the WRITE button or depress the A/B foot
switch to proceed to the next test step.
4.2 Start with the leftmost control.
Potentiometer: from full-counterclockwise (FCCW)
position to full-clockwise (FCW) position
As the knob travels, the LED corresponding to the
scale will light:
(These values are just as a guide.)
When all travel ranges of the potentiometer has been
sensed, the POWER INJECTION LED lights in green.
The unlit LED is a sign of NG.
Press the WRITE button or depress the A/B foot
switch to proceed to the next control test.
When the next item to be test is a potentiometer,
repeat the step.
SHAPE switch: turn it on and then off. The green
POWER INJECTION LED indicates that the switch's
on and off states are correctly detected.
Turn on CHORUS switch and verify lighting CHORUS
LED. Then, test the potentionmeter.
PHONES socket: insert the standard plug into the
socket and then withdraw.
The POWER INJECTION LED lights in green

When this procedure is following the test 5 above, the
LEDs A, B and WRITE are blinking (standby). Press the
WRITE button to start loading.
While loading, the WRITE LED blinks and at the end of
loading the LED A will light.
Turn off the POWER switch.
CAUTION:The following procedure will erase user data.
♦Checking input/output level, noise level and
power limiter
Connect 8Ωload to speaker out WOOFER and TWEETER.
To check power limiter, connect a 680Ωload to the hot and
cold terminal of LINE OUT BALANCED socket, respectively.
1. Entering the checking mode
1.1 Set AMPLIFIER TYPE switch to SOLID STATE.
1.2 Set MASTER knob to 10.
1.3 Set GND LIFT switch to OFF.
1.4 While pressing MANUAL and WRITE buttons, turn on
POWER switch.
1.5 LEDs "A" and "B" light. Press MANUAL button and the
LEDs turn off. Now the unit is in the checking mode.
2. Checking input and output levels
2.1 Set the following controls:
AMPLIFIER TYPE switch: SOLID STATE
MASTER knob: 10
Other controls: Don't care
2.2 Check input and output levels:
Apply 1 kHz, sine wave signal to INPUT. Check level
at various points by referring to the corresponding
level denoted on the circuit diagram.
3. Checking noise level
3.1 Set the following controls:
AMPLIFIER TYPE switch: TUBE
MASTER knob: 10
Other controls: Don't care
3.2 Check noise levels:
Leave INPUT sockets disconnected.
3.2.1 With panel settings as mentioned 3.1 above:
Measuring point: Speaker output WOOFER (8Ω)
Noise level: −32.0 dBm (IHF-A)
