system in Test Mode.
Display Setup screen with the FUN key, and press ADJ key for making adjustment.
Note 1: If adjustment becomes impossible as a result of having input incorrect values,
clear the E2PROM first and then conduct the adjustment. This can be done by resetting
while pressing VOLDW and OPEN/CLOSE keys. When this is done, the machine also
loses the mechanical positions. Therefore, this must also be adjusted again.
4. Confirming on the

L303
1. Turn VR301 [RF-AGC] fully to the right.
2. Apply DC2.0V to TP [IF AGC] (IC300 pin36).
3. Feed fo=45.75MHz, Mod=1kHz, AM60%, Level=100dB

into TP [IF]
(A100 pin8).
4. Observe the TP [VIDEO] (IC300 pin8) waveform on an oscilloscope and
adjust L303 for maximum level.
