8-3. How to operate with the circuit board without the cassette controller assembly.
In this method, if the procedure is followed incorrectly there is danger of damaging the mechanism and the tape, so except in special cases, such as when measuring the VSR torque, do not perform this procedure. Normally operate this unit with the cassette controller assembly attached. Be sure to follow each caution mentioned.

(1) Apply DC3 ~ 4V to the loading motor to enter the standby mode. (2) Securely press the movable piece L of the down SW with cellophane tape or similar to turn on SW. (Take care that the movable piece turns only in the shown arrow direction.) Note: To enter REC mode, press the pin of the recognition switch M . (Unnecessary in other modes.) (3) Set the test mode (T-01) with the adjustment remote controller without putting the tape, and the mechanical operation will become possible with the mode key. (4) For ejection, remove the tape of (2).

8-4. Phase matching

Fig. 7. LOADING START mode

Referring to Figs. 8 and 9, align the phase for the following parts. (1) Eject lever (2) Eject control lever (3) Mode SW (4) Main cam (5) Sub cam Note: Before disassembly, sufficiently check the marker position. Note: When installing the joining gears, verify that the phase matching holes of the main cam and subcam are aligned to the hole of the chassis. Note: After the phase is aligned, turn the mode SW with hand, and verify that it turns nearly one turn. (After verification, return it to the original position.)
