1. Playback the test tape VT703 (10KHz) or equivalent.
2. Adjust the head azimuth screw to obtain maximum
output and both output of L / R is in 3dB.
3. Put on the screw lock paint after alignments.
1. Insert the recording tape in deck-B.
2. Starting the recording.
3. Adjust the oscillation frequency to 80KHz+/-3KHz by
core of Oscillation coil of L301.

1. Set the Signal Generator signal to 530KHz the feed
to Loop Antenna.
2. Receiving the signal and the adjust the OSC coil (L2)
obtain the V.T is 1.40V +/-0.05V.
3. Change the receiving frequency to 600KHz (603KHz).
4. Adjust the Antenna coil ( L2 ) obtain maximum
sensitivity. (Adjust the SSG output to out of AGC range.)
1. Set the receiving frequency to 530KHz.
2. Feed the 450KHz signal to AM antenna input.
3.Adjust the IFT Block T1 obtain to maximum output.
(Adjust the SSG output to out of AGC range.)
