  • Page 85 1. Tape Interchangeability Alignment Note: To do these alignment procedures, make sure that the Tracking Control Circuit is set to the preset position every time a tape is loaded or unloaded. (Refer to page 2-3-4, procedure 1-C, step 2.) Equipment required: Dual Trace Oscilloscope VHS Alignment Tape (FL8NW) Guide Roller Adj.

Check to see that the tape runs without creasing at Alignment of Tape Path Take-up Guide Post [4] or without snaking between Guide Roller [3] and ACE Head. (Fig. M3 and M5) Purpose: 4. If creasing or snaking is apparent, adjust the Tilt To make sure that the tape path is well stabilized.
