TEST PROCEDURES
GENERAL TEST SETUP
Load the outputs as follows:
Headphone output-33W, 1% load.
Audio (A, B, Fixed) outputs-10kW load.
 Note: The remote control or console
buttons can be used to select sources in
these procedures.
1. AUX Gain Test
1.1 Select AUX.
1.2 Apply a 500mVrms, 1kHz signal to the
left (right) AUX input. Adjust the volume to
maximum. Reference a dB meter to the
applied signal.
1.3 Ground the TAPE, VIDEO  and the right
AUX inputs.
1.4 Measure the outputs according to the
following...

TEST PROCEDURES
5. Headphone Mute
5.1 Select the AUX input.
5.2 Apply a 500mVrms, 1kHz signal to the
L/R AUX input.
5.3 Insert a mini-jack into the headphone
output. The A output should mute.
FM ALIGNMENT TESTS AND
ADJUSTMENTS
Unless otherwise noted, set an RF genera-
tor to 98.1MHz, 40dBf, 1kHz, mono modu-
lation, pilot off, 100% (75kHz deviation).
1. Front End Mixer Coil Adjustment
1.1 Adjust the FM front end (TUNER) mixer
coil until a maximum DC voltage is mea-
sured at U301 pin 25. Adjust the coil...

AM ALIGNMENT PROCEDURES
Test setup: Connect the generator to a
standard radiating loop. Unless otherwise
noted, set an RF generator to 70dBu field
strength, 400Hz, 30% modulation.
See Figure 9.
Figure 9. AM Test Setup
The equivalent field intensity is 26dB less
than the generator output level or 1/20
th of
the output voltage.
1. AM  Sensitivity Alignment
1.1 Set the RF generator so that the field
strength at the units antenna is 70dBm
(70dBm V/M).

read approximately 90mVdc.
2.4 Simulate a closed CD door by placing
an object between S501s two black posts
(the CD door latch can be used). Select CD
(S413).
2.5 After the focusing operation is com-
pleted, press ERASE (S403). The meter
should change from its previous reading in
step 2.3 (it will drop). If not, remove power
and repeat the test.
2.6 Adjust R511 until the meter reads
between -7 to 17mVdc.

5. Focus Gain (FG)
5.1 Advance the fixture to FG and set the
voltmeter to read AC voltage.
5.2 Simulate a closed CD door by placing
an object between S501s two black posts
(the CD door latch can be used). Load the
test disc, select CD (S413), and play track
2.
5.3 Adjust R527 until the meter reads
between 380 to 420mVrms.
6. Tracking Offset Readjustment
6.1 Refer to procedure 2 and readjust if
necessary.
