1. Connect a DC voltmeter between TP.1 and TP.2(GND)
(FWD), TP.3 and TP.4(GND) (REY) onthe CONTROL PC
board.
2. Play the middle part of test tape MIT-5511 and adjust
the following so that the voltmeter shows the values
in the above table.

4-5 TAPE SPEED ADJUSTMENT
1. Connect a frequency counter to the deck as shown in
Fig. 4-11.
2. Playing the mid portion of an HIT-t11 test tape in
FHO and REV directons, adjust the semi-fixed
resisrtor on capstan motor so that tape speed
becomes 3,000 Hz + 5-Hz. An insulate and non-
netallic flat-head screwdriver shoukd be used for
this adjustment.
3. In both FHD and REV play modes, check that the
folfowing values are obtained at the beginig and at
the end of the tape.
