How to open the cabinet
1. Turn the rod antenna upward.
2. Put the edge of a coin into the slit between the cabinet and the
rear cover. Twist the coin slowly, and the rear cover will unlock
and open slightly (about 1/5” or 5mm).
. Turn the rod antenna downward.
4. Unlock the top part of the rear cover, pushing it gradually in the
arrow (A)-marked direction. Then, the rear cover will separate
from the cabinet.
5. Be careful not to damage the lead wires when closing the rear
cover.

How to attach the tuning shaft
Turn the tuning shaft counterclockwise and the variable capacitor
clockwise as far as they move. Match A and B, as illustrated, and
immobilize the tuning shaft, using an E-ring.

ALIGNMENT PROCEDURES
GENERAL ALIGNMENT CONDITIONS
1. The position of volume control is at maximum position.
2. Signal input must be kept as low as possible to avoid voerload.
3. Use an output meter of the highest possible sensitivity.
4. Standard modulation is 400 Hz at 30% amplitude (for AM) and 22.5 kHz deviation (for FM).
AM BAND — Band selector switch in AM position.

How to adjust the sensitivity of LED for tuning
Do as instructed below:
@ Set the band switch to FM.
@ Reduce the signal level to zero.
@ Adjust the variable resistor R307 until current flowing
to D304 becomes 20UA.
