SECTION 1
ELECTRICAL ADJUSTMENT
NOTE :
1. The adjustments should be performed in the order given.
2. The adjustments and measurements should be perfomed for both
L-ch and R-ch unless otherwise indicated.
3. L-ch adjustment should be completed before performing R-ch
adjustment.
OSCILLATING FREQUENCY Adjustment
Procedure :
No signal state.
1. Connect the frequency counter to TP(CL4) (L-ch) and TP (CL-
54) (R-ch).
2. Adjust with RV1 (L-ch) and RV2 (R-ch) so that the reading on
the frequency counter becomes the specified value.
Specified Value:
L-ch RV1 2.3MHz ±2kHz
R-ch RV2 2.8MHz ±2kHz
