Tracking

Adjustment

A

tracking

adjustment

has

been

preset

at

the

factory.

However,

some

slippage

may

take

place

during

shipment.

You

can

ensure

precise

tangential

tracking

by

following

this

procedure:

1.

Make

sure

the

tracking

shaft

is

rotating

(black

cylinder,

visible

through

opening

in

top

plate).

If

it

is

not,

rotate

the

platter

one

revolution

in

reverse

direction,

then

try

again.

2.

Play

a

33-1/3

rpm

record.

3.

Allow

the

arm

to

track

across

about

one

inch

of

the

record.

4.

Observe

whether

the

arm

is

leading

or

lagging

the

notch

in

the

restrictor

arm.

If

the

arm

is

lined

up

perfectly

with

the

notch,

and

the

arm

cues

straight

up,

no

further

adjustment

is

necessary.

If

not,

refer

to

Step

5.

5.

Move

cue

lever

to

rear.

The

tracking

adjustment

knob

is

located

on

the

rear

of

the

carriage.

If

the

tonearm

is

leading

the

notch

in

the

restrictor

arm

—tending

toward

the

center

of

the

record

—turn

the

adjustment

knob

slightly

clockwise

as

viewed

from

the

rear.

If

the

tonearm

is

lagging

the

notch

—tending

toward

the

beginning

of

the

record

—turn

the

knob

slightly

counterclockwise.

Repeat

the

procedure

until

the

tonearm

remains

closely

lined

up

with

the

notch

as

it

tracks

across

a

complete

record.

Cleaning

the

ST5

ST5

maintenance

is

limited

to

periodic

cleaning

and

dusting.

In

particular,

clean-

ing

the

slide

rod

and

tracking

shaft

near

the

back

of

the

turntable

will

help

keep

your

ST5

in

peak

operating

condition.

Move

the

cue

lever

to

the

rear.

Using

the

control

arm,

move

the

carriage

to

the

left

end

of

its

travel

to

expose

the

stainless

steel

slide

rod.

Clean

the

slide

rod

with

a

soft

cloth

or

cotton

swab

moistened

with

isopropyl

alcohol.

Using

the

control

arm,

move

the

carriage

to

the

right

end

of

its

travel.

The

tracking

shaft

is

the

black

cylinder

visible

through

the

carriage

opening.

(You

can

see

the

tracking

shaft

turn

when

the

platter

rotates.)

Clean

the

tracking

shaft

as

you

did

the

slide

rod.

The

stainless

steel

parts

of

the

turntable

(for

example,

the

slide

-weight

and

control

arm)

may

be

similarly

cleaned.

Remove

dust

using

the

soft

brush

attachment

of

a

canister

-type

vacuum

cleaner

rather

than

a

dusting

cloth

or

feather

duster.

Clean

the

dust

cover

with

a

soft

cloth

and

l

iquid

glass

cleaner.

Never

apply

alcohol,

solvents,

or

abrasives

to

the

dust

cover.

Keep

the

dust

cover

closed

when

the

ST5

is

not

in

use

to

prevent

dust

from

accumulating.
