2-1. SERVO CIRCUIT ADJUSTMENT
• These adjustments should be carried out upon completion of the tape transport adjustments.
• If the tape transport adjustments (except the tilt adjustment) are done after these adjustments, follow the procedures again in
section 2-1-3. "SWITCHING POSITION ADJ."
• When a cassette tape is loaded, auto-tracking will be set immediately after starting the first playback. As this will deviate the
tracking center set, be sure to press tracking buttons (+) or (-) once directly after starting playback to prevent auto-tracking from
being set.
