2 ) Insert the tension gauge at point “ A ” (shown in Fig. 4.8) and set R3 (EDIT-T. UP) for
the reading of tape tension of 120g. Next, insert the tension gauge at point “ B ” and set
R4 (EDIT-SUPPLY) so that the reading of tape tension is 120g.
4.2.6.6 At PLAY Mode
1) Put the transport in the PLAY mode by depressing the lPLAYl button on the main unit.
2) Set R2 (PLAY-T. UP) so that the reading of tape tension at “ A ” is 200g. In the same
way, set R5 (PLAY-SUPPLY) so that the reading of tape tension at “ B ” is 1 60g.
4.2.6.7 At Fast Winding Mode
1) Put the transport in the F.FWD mode by depressing the IF. FWD] button on the main unit.
2) Set RI (FF) so that the reading of tape tension at “ A ” is 350g.
3) Put the transport in the RWD mode by depressing the |REWIND| button on the main unit.
4) Set R6 (RWD) so that the reading of tape tension at "B ” is 350g.
4.2.6.8 At EDIT mode
1 ) Put the transport into STOP mode by depressing STOP| button on the main unit.
2) Depress |CLR| (clear) button of the controller to release the MECHANISM-ADJUST mode.
3) With putting G24S/G16S on the vertical position, put the connector J4 back on the DD
CAPSTAN PCB.
4.2.6.9 Checking the Tape Tension (refer to Fig. 4.8)
1) Put the G24S/G16S in the MECHANISM-ADJUST mode (refer to 4.2.6.4 3))
2) Put the transport in the EDIT mode by depressing [STOP| button on the main unit.
3) Check the tension at “ A ” and “ B ” . Tension at “ A ” and “ B ” should be 100 ~ 130g. And
the difference of the tension between at “ A ” and “ B ” should be less than 5g.
4) Put the transport in the PLAY mode by depressing the |PLAY button on the main unit.
And confirm that tension at “ A ” is 190g ± 10g and tension at “ B ” is 170 ± 10g. (Caution:
since the capstan motor rotates at a speed of 3 % ips in the MECHANISM ADJUST mode,
T.UP side tension should be 10g lower than the adjusted value in item 4.2.6.6, and supply
side tension should be 10g higher than the adjusted value in item 4.2.6.6.
