Install the pickup(Refer to the removal of the pickup from the mecha unit.)When handling the pickup, refer to the precautions on how to handle the PU listed below.2. Method 1:Connect the oscilloscope according to the AGND3 standards with reference to the connection diagram so that the RFsignals can be monitored.Method 2:The device does not need to be set. Proceed to the procedure 3.3. Turn ON the power of the product.4. Start the simplified FE test mode.(Regarding how to start the test mode and the operating procedure, refer to the clause on the service test mode.)5. Load the disc for adjustment (TDV582).6. TEST MODESelect “3: Skew Adjustment.”Adjust the Skew using a driver while checking the RF value.Refer to the following pages concerning the locations to make SKEW adjustment.Method 1:Slightly turn the skew adjusting screw A while checking the RF wave level by the oscilloscope and makeadjustment so the wave level would reach its maximum.Next, slightly turn the skew adjusting screw B so the wave level would reach its maximum.Slightly turn the skew adjusting screw A again so the wave level would reach its maximum.(Make adjustment in the order of A->B->A and in the end complete adjustment by turning each screwin the clockwise direction.)Method 2:Slightly turn the skew adjusting screw A while checking the value of the RF level through the OSD display so the wavelevel would reach its maximum.Next, slightly turn the skew adjusting screw B so the level would reach its maximum.Slightly turn the skew adjusting screw A again so the level would reach its maximum.(Make adjustment in the order of A->B->A and in the end complete adjustment by turning each screw in theclockwise direction.)
