1) Main Bang suppression Level (MBS L) is set to 0.
2) EEPOT, U14 is set to minimum. (EEPOT initialization with “L” level of U14 #7)
3) EEPOT gets into step-up mode (U14 #2 is H.) to measure output video level at each step.
The step is changed by pulses applied to U14 #1. The step where the output level is 2.2 V is
memorized.
4) EEPOT gets into step-down mode (U14 #2 is L) to find and stores the step number where
the output level is 2.2 V.
5) Averaging the step numbers found in steps 3 and 4 above, and saving onto eepot. The stored
value is not erased when power is turned off.
6) MBS L is reset to the value previously used.
7) The value obtained in step 5 is stored onto the EEPROM. Thus, the EEPOT can be set for
both video signals from the scanner unit and the external radar.
