It is on processor board. --- End quote --- I mean the top cover of the 8920A host, not the metal shielding cover of the module board. Only when the upper cover of 8920A host is closed and "LOW RANGE ENABLE" is pressed, the effect will be displayed. If you need me to test it, I can't guarantee the results.Do you need it? |

Press "LOW RANGE ENABLE", 2Mhz indicator light is not on, R240 left: -13.03 right: -14.96 |

"Low Range" was not switched. You can control it via 2MHz indicator. Please measure the voltage on TP1 by DVM. |

Think it is Ok. You should not make any adjustments as this requires more precise measurement instruments than 8920A. |
