∗1. Uncertainty. ∗2. “L” when erasing protection tab is bent, “H” when not bent. ∗3. Pulse of period in proportion to reel rotating speed. ∗4. Approx. 2 msec period “H” pulse. ∗5. Pulse at tape running.
∗6. Normally “L”. 2 msec period “H” pulse when tape top or tape end is detected. ∗7. When transition to UNLOADING direction: L.
When transition to LOADING direction: H. When CAM motor is stopped: Hi-Z.
∗8. When RVS slow: Mode 1=“L”
When RVS slow: Mode 2=“L” When RVS slow: Mode 3=“H” When RVS slow: Mode 4=“L”
