VOLTAGE SELECTION
Before operating the unit on mains, check the preset voltage.
If the voltage is different from your local voltage, adjust the
voltage as follows: Slide the AC power supply socket cover
by a little loosing one screw to the visible indication of the side
of your local voltage. See Figure 2-3.

MECHANICAL ADJUSTMENT
Except for the following item, refer to the RD620X Service
Manual already issued.
n RECORD/PLAYBACK HEAD AZIMUTH ADJUSTMENT
As shown in Figure 5-1, connect instruments, and adjust
the head azimuth adjusting screw so that the output signals
from both channels will have maximum waveform with the
same phase in right and left.

GENERAL ALIGNMENT INSTRUCTION
Should it become necessary at any time to check the alignment of this receiver, proceed as follows;
1. Set the volume control (VR103) to maximum.
2. Attenuate the signals from the generator enough to swing
the most sensitive range of the output meter.
3. Use a non-metallic alignment tool.
4. Repeat adjustments to insure good results.
5. Set the Function Selector Switch (SW102) to “radio”
position.
AM IF/RF ALIGNMENT
l Set the signal generator to produce a signal of 400Hz, 30%,
AM modulated.

1-1 Check the alignment of the receiver antenna coil by
bringing a piece of ferrite (such as a coil slug) near the antenna
loop stick, then a piece of brass. If ferrite increases output,
loop requires more inductance. If brass increases output, loop
requires less inductance. Change loop inductance by sliding the
bobbin toward the center of the ferrite core to increase induct-
ance, or away to decrease inductance.
