RF MODULATOR UNIT
1. DC balance adjustment (VR301)
While observing the waveform with a oscilloscope at
pin 13 of IC301, adjust VR301 to minimize the
waveform level.
TEL 13942296513 QQ 376315150 892498299
ADJUSTMENT
LPS initial position adjustment procedure
Connect the changer to the H/U. While holding the
magazine eject button of the changer, press the reset button
of the H/U and, in about 1 second, release the magazine
eject button. Press the CD button of the H/U to enter the
TEL
E-88 mode. Move the mechanism deck to around the 1st
stage by pressing the DISC- or DISC+ button.
Insert the adjustment tool into the tool hole on the changer
mechanism. Then press the DISC+ button to move the
mechanism deck until the mechanism’s slider hits the
adjustment tool. When the motor locks (stops) press the
REPEAT key of the H/U.
When the REPEAT key is pressed, the mechanism moves
automatically to the 1st stage and the initial position
adjustment completes. (The data is written in the E2PROM
at this time.)

2. PLL control voltage adjustment (VC301)
First set the transmission frequency to *87.9 MHz with
the commander, then adjust VC301 so that the DC
Voltage at the + pole of C317, measured using a
multimeter or digital tester, is + 3V (± 0.1 V).
3. Modulation level adjustment (VR303)
The method using a standard receiver or tuner.
Adjust VR303 so that the output level from the
standard receiver or tuner is as specified.
