    ADJUSTMENT OF THE TAPE TRANSPORT SECTION. Generally, tape transporting section has been precisely adjusted in the factory and does not require the ordinary readjustment. But there is the case that tape noise or impact on the deck mechanism, tape transporting section readjustment is required. In adjustment of the tape transmission section refer to the following flow chart.
