Press Ipreset] ?g#?jm@J ~.~@jK$&~ (where X is the sequence number). � If the marker value is ~7, you have completed this procedure. � If the marker value is >7, readjust “F’N VCO TUNE” to 7. Then repeat steps 2,3, and 4 to conlirm that the channel 1 and channel 2 markers are still above and below the reference line respectively. How to Set Up the High/Low Band Transition Adjustments / ,.; _ _ _ ; l. Press B ~~~~:~~~~~?~~~ (where X is the sequence number). 2. Observe the VCO tuning trace: � If the left half of trace = of1000 mV and right half of trace = 100 to 200 mV higher (one to two divisions): no adjustment is necessary. w If the adjustment is necessary, follow these steps: a. Remove the upper-rear bumpers and top cover, using a TORX screwdriver. b. Adjust the VCO tune (Al2 C85) to position the left half of the trace to of125 mV. This is a very sensitive adjustment where the trace could easily go off of the screen. c. Adjust the HBLB (Al2 R68) to position the right half of the trace 125 to 175 mV (about 1 to 1.5 divisions) higher than the left half. Adjustments and Correction Constants 3-63
