KDC-C565FM/C465FM
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.
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.
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 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.)
