SOLENOID SL-2 (Refer to Figs. 1, 2)
1) Adjust left/right Brake Band Support positions so
that at stop mode, Brake Lever A and Brake Lever
B display 180° angle relativity.
2) Under the conditions described in 1) above, adjust
installation angle position of Microswitches SW-8
and SW-9 so that the clearance between the brake
. lever and brake band lever is 1.5 mm.
3) Adjust installation position of the Brake Solenoid
so that at playback mode, the brake band sepa-
rates from the brake drum.
2. BRAKE TENSION ADJUSTMENT (Refer to
Figs. 1, 2)
1) Adjust installation position of the Spring Rack so
that brake tension is 500g.
2) After brake tension adjustment, adjust installation
position of the Brake Band Guide so that at all
modes except stop mode, the brake band com-
pletely separates from the cloth tape on the brake
drum.

are
vital
to

performance,
be
sure
that

or
other
magnetized
tools
in

3.
Use
only

is
likely
to
occur
when
using

4.
Demagnetize

2) Ground test points T.P (Fig. 15)
3) Set Dolby Switch to OFF position.
4) Supply a 5 kHz, —10 dBm signal which has been
verified with a frequency counter from the audio
frequency oscillator and confirm that at this time
the indication of the high-sensitivity VTVM con-
nected to terminal (B) is 0 dBm.
5) Reduce the output of the audio frequency oscil-
lator by —30.5 dB from the condition outlined in
item 1-4) (S kHz, —40.5 dB) and at this time
confirm that the indication of the high-sensitivity
VTVM connected to terminal (B) is —30.5 dB.
6) Set Dolby Switch to ON position and adjust
semi-fixed resistor VRI 1 kB to obtain a —-20.5
dBm indication on the high-sensitivity VTVM
connected terminal (B).
7) Disconnect ground wire from test point T.P
(grounded in item 1—2) and at this time adjust
semi-fixed resistor VR2 5 kB to obtain a —22.5
dBm indication on the high-sensitivity VTVM
connected to terminal (B).

PART-2. PLAYBACK DOLBY N.R CIRCUIT
ADJUSTMENT
This adjustment is carried out in essentially the same
way as the recording Dolby circuit adjustment.
Disconnect the wire connected to input and out put
terminals(A’) and (B), connect and audio frequency
oscillator to terminal(A’), and connect a higi=sensi-
tivity VTVM to terminal(B). Turn semi-fixed wesistor

1) Set Dolby Switch to OFF position and suply a 5
kHz, 10 dBm signal which has been verified with
a frequency counter from the audio frequency
oscillator, Confirm that the high-sensitivity VT "VM
indication at this time is O dBm. Next, lower the
oscillator output by —22.5 dB and confim that
the high-sensitivity VTVM indication is —21.5 dB.
2) Set Dolby Switch to ON position and at this time
adjust semi-fixed resistor VRI 1 kB to oltaän a
—32.5 dB high-sensitivity VTVM indication.
Next, disconnect ground wire from test pots T.P
and adjust semi-fixed resistor VR-2 5 kB toob tain
a —30.5 dBm indication.
