For this adjustment, it is recommended to attach the cassette compartment to the unit.
If the cassette compartment does not attach to the unit, interrupt the photo interrupter (cassette compartment
lock switch) mounted on the SE-210 board using a black paper or equivalent so that the unit is in the cassette
lock state.  After placing a weight on a FWD back tension measuring cassette tape so as not to rise it up,
carry out this adjustment.
