T2 guide height adjustment (1) Turn the tracking control volume using a screwdriver so that the output level at the center of the envelope waveform is 80 % of the maximum output (waveform B shown in the figure). (2) Turn the upper flange of the T2 guide using a tape guide adjustment screwdriver so that the falling edge of the envelope waveform makes flat as shown in figure C. (3) Check that tape runs in contact with the upper flange of the T2 guide. (4) Tighten the set screws on the upper flange to the following tightening torque. Tightening torque: 9 x 10_2 N.m (0.9 kgf.cm) 3. T2 guide height check Repeat the mode change from EJECT mode to PLAY mode 3 times.
