1. This rating does not apply when using the internal zener reference in conjunction with an external pass transistor.
2.
3. Except for pull-in range testing, tune oscillator trimmer capacitor for free running frequency of 3.579545MHz 10Hz.
4. Set Switch 1 to Position 2, detune oscillator 250Hz, set Switch 1 to Position 1, and check for oscillator pull-in.
5. Set Chroma Gain Control to minimum position (CCW).
