HORIZ FREQ—Adjust for 15,750 Hz. This can be done by connecting an oscilloscope adjusted to 7875 Hz. horiz sweep to point M on the sweep printed circuit board, adjust R54 for 12 pulses. Refer to Fig. 16 waveform chart.
This is what is in the service manual but unfortunately it does not have the waveforms it refers to. I'm not sure I understand the instructions anyway...when I use my scope to measure a frequency, I just hook on the probe and press auto!!!
