See Fig.1 and Fig.4 on page XX
Adjustment Point 1. LW OSC of RF215 (Black core) for Frequency Range.
2. LW ANT. Coil of RF215 (Red core) for Tracking.
Adjustment Method 1. Frequency Range
Set the tuning frequency of UNIT to 150kHz.
Adjust RF215 (Orange core) so that leading of DC VOLT METER reads 2.3± 0.1V
2. Tracking
Set the tuning frequency of UNIT to 210kHz.
Adjust RF215 (Red core) so that output level reads maximum.
