SAFETY INSTRUCTIONS
PRECAUTIONS DURING SERVICING
1. Parts indentified by the A(*) symbols are critical for
safety Replace only with parts number specified.
2. In addition to safety, other parts and assemblies are
specified forconformance with such regulations as
those applying to spurious radiation.
These must also be replaced only with specified re-
placements.
Examples: RF converters, tuner units, antenna selector
switches, RF cables, noise blocking capacitors, noise
blocking filters, etc.
3. Use specified internal wiring note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
4. Use specified insulating materials for hazardous live
parts. Note especially:
1) Insulation Tape
2) PVC tubing
3) Spacers (Insulating Barriers)
4) Insulation sheets for transistors
5) Plastic screws for fixing microswitch (especially in
turtable)
5. When replacing AC primary side components(transfor-
mers, power cords, noise blocking capacitors, etc.),
wrap ends of wires securely about the terminals be-
fore soldering.
6.
Observe that wires do not contact heat producing
parts (heatsinks, oxide metal film resistors, fusible re-
sistors, etc.).
7. Check that replaced wires do not contact sharp edged
or pointed parts.
8. Also check areas surrounding repaired locations.
9. Use care that foreign objects (screws, solder droplets,
etc.) do not remain inside the set.
SAFETY CHECK AFTER SERVICING
After servicing, make measurements of leakage-current
or resistance in order to determine that exposed parts
are acceptably insulated from the supply circuit.
The leakage-current measurement should be done be-
tween accessible metal parts (such as chassis, ground
terminal, microphone jacks, signal input/output connec-
tors, etc.) and the earth ground through aresister of
1500ohms paralleled with a0.15 \if capacitor, under the
unit’s normal working condition. The leakage-current
should be less than 0.5 mA rms AC.
The resistance measurement should be done between
accessible exposed metalparts and power cord plug
prongs with the power switch (if included) “ON”. The re-
sistance should be more than 2.2 Mohms.

3-4-1. DAC OFF-SET ADJUSTMENT
1) After turning the unit on, press the EDIT SAMPLE button. Next use the DATA knob to select “SINE,” then press the
[REC 2] F3/C button. Connect the audio signal generator to the LEFT input and sample aIKHz sine wave. Adjust the
signal level so that the output is -6dBm. Select “tim: s” with the CURSOR knob, then select “10.00” with the DATA
knob. Next press the [ARM] F8/H button to sample a1KHz tone.
2) Press the EDIT PROGRAM button, then press the [KGRP] F2/B button. Select “change number of KEYGROUPS” with
the CURSOR knob, then select “12” with the +/< button. Next select “note on sample COHERENCE” with the CURSOR
knob and select “ON” with the DATA knob.
3) Press the [SLCT] FI /A button, then press the [OUT] F4/D button. Next select “loudness” with the CURSOR knob and
press the ENT/PLAY button. Set the DATA knob so that the output from OUTPUT (L CH, RCH) is +11 dBm. Select
“eft out” with the CURSOR knob, and 14% with the DATA knob only when adjusting the send level.
4) Press the ENT/PLAY button and adjust the VR101 (LEFT), VR201 (RIGHT) and VR301 (SEND) on the AD PCB so that
DISTORTION is less than 1%.
5) Select “mono out” with the CURSOR knob. Use the DATA knob to select channels between CH1-CH8 and adjust the
