We want to thank you for selecting the SL-1 015.
For optimum performance, we recommend that you
read these instructions carefully.
The SL-1015 is a high performance turntable
system which consists of a tonearm (EPA-500)
designed with compatibility of the cartridge and
tonearm

in

mind a high performance turntable base
(SH-15B 1) designed with emphasis on its damping
characteristics produced by one-piece molding of
special viscoelastic material and a quartz
synthesized system direct drive turntable (SP-15)
capable for the first time in the world of digital pitch
control at

±9.9%

through 0.1 % steps.

If

you purchase the optional tonearm unit according

to the characteristics

of

the cartridge you use, you
can upgrade your system as easily as replacing the
headshell.

batteries

become weak, replace all of them ;

do

not

attempt

to mix old and new

batteries

.

2.

Do

not

combine

different

types

of

batteries

together. For

ex

ample

although

they

appear

interchangeable

because

they are the

same

size ,

mercury

batteries

(MR44) and

silver

oxide

batteries

(SR44)

have

different

voltage. Also,do

not

attempt

to mix

batteries

of

different

brands. This

is not only

uneconomical

, but the unit will

not

be

able

to

display

its

performance

to the full.

3.

After

use,

be

certain

to return the

unit's

power switch to

the

[off)

position. Also, when not utilizing for

prolonged

periode,

and store them.

4.

Remove

worn

out

batteries

and

dispose

of them

promptly.

5. Do not

attempt

to recharge

batteries,

or

short-circuit

,

break

open, heat

or

throw

into

a fire .

6. When

changing

the

batterie

s, confirm that their contact

surfaces

, as

well

as the

terminals

of the

stylus

pressure

gauge

, are clean and uniformly shaped.

At this time, be

sure

that the

batteries

are inserted

according to the

[+)

and [ - )

indications

.

• Battery life

When

the

batteries

become

worn

down

, the indicator needle

will

not

reach the [ ... ) pOint when the gain control knob is

turned to

[+

),

In

some

cases

the

LED

lamp will light,

butthe

unit

will not

be

effective

for s

tylus

pressure measurement.

Therefore, replace

the

batteries

. Refer to the section on

"Adjustment

of

stylus

pressure

gauge"

.

The

life of the

batteries

during

consecut

ive use is

about

1 0

hours

. (National

silver

oxide G13

batter

ies used at 20°C.)
Note:
Ordinarily, battery

life

becomes

shorter

when

used

at low
temperatures (below around 5°C.), Also, they do not
function well in high

humidity. Therefore

, store them

in

a

dry

place

with few

temperature

changes

.

• Adjustment of anti-skating (See

Fig,

18,)

After

and

20,)

The

proper

height

of

the arm

lift

(the

distance

of

the

stylus

tip

from the disc with the cueing

lever

in the [up] position) is

about

5 to 10 mm. If adjustment

becomes

necessary,

follOW

the

procedure

below:

1. Set the cueing

lever

to the [up] pOSition ,

2, Slightly loosen the

arm-lift

fixing screw, and raise or

lower

the arm
