Description

The

KS-19594

dialer

is

a

magnetic

recording

repertory

dialer

intended

for

use

in conjunction with

a telephone

set.

The

dialer

is

placed

in a convenient

location

near

the

telephone

set

and

is

electrically

con-

nected,

although

it

does

not

interfere

with

normal

telephone

set

usage.

This

dialer

consists

of

three

individual component

items:

a KS-19594

Ll

dialer

unit containing the

record-reproduce

mechanism,

electronics

and

control

circuit;

a KS-19594 L2

dial-in

unit

for

recording

numbers

into the

repertory;

and a

wall-mounted

KS-19594 L3 power supply.

The

dial-in

unit

connects

to

the

dialer

unit by

means

of

a plug and

cord

and

is

to be

detached

and

stored

when not

in

use

for

recording.

The KS-19594

dialer

is

the

same

as

the

Model E3

MAGICALL

except

as

authorized

herein,

manufactured

by

the DASA

Corporation,

Andover,

Massachusetts,

and

is

their

proprietary

design.

A

power

source

of

115volts,

60

cycles,

is

required

for

the

operation

of

this

dialer.

The

dialer

unit

and the

dial-in

unit

are

furnished

with a

choice

of

five

different

colors

of

cover

and

cords.

The

cordonthedial-inunit

(KS-19594

L7

cord)

is

permanently

attached

by

means

of

solder

connec-

tions.

Two

cords

are

provided

with the

dialer

unit,

one

for

connection to the power supply (KS-19594

LS

cord),

the

other

(KS-19594

L9

cord)

to

the

associated

telephone

set.

The

design

of

the

KS-19594

dialer

permits

com-

plete

interchangeability

of

all

component

items

(dialer

unit,

dial-in

unit,

cartridges,

and power supply)

with-

out

requiring

any

readjustment.

The

KS-19594

Ll

dialer

unit

is

the

basic

compon-

ent

of

this

dialer

and

contains

the

record-reproduce

mechanism,

electronics

and

control

circuit.

It

in-

cludes

a KS-19594 L4

cartridge

providing

for

400

entries,

a KS-19594

LS

cord,

a KS-19594 L9

cord,

and

a KS-19594

Lll

cover.

A

motorized

scan

mechanism

provides

for

rapid

movement

of

the

recording

tape

while final

positioning

may

be done with a

manually

2

operated

knurled

wheel.

The

cartridge

is

easily

re-

movable

and

requires

merely

lifting the

access

cover

and

depressing

the

release

bar

to

permit

the

cartridge

to

snap

out

of

the bottom of

the

dialer

unit. When

desired,

a KS-19594 L5

cartridge

may

be

substituted

for

increasing

capacity

to 1000

entries.

The

KS-19594

L2

dial-in

unit

is

equipped with a

KS-19594 LlO

cover

and a KS-19594 L7

cord.

This

attached

plug and

cord

provides

for connection to

the

dialer

unit

during

recording

of

numbers

into the

reper-

tory.

The

dial-in

unit

is

used

only

during

the

record-

ing

process

and

must

be

detached

during

calling.

It

is

provided

with a

motor-assisted

telephone-type

dial

and a

"wait"

lamp

for

use

during

the

recording

process.

The

KS-19594 L3 power supply

is

a

wall

-mounted

unit which

operates

from

a

115-nlt,

60-cycle

outlet.

It

provides

power

for

operation

of the

dialer

at

two

voltages:

18

volts

de and

29

volts

ac.

A

4-conductor

cord

(KS-19594

LS

cord)

provides

for

connection to

the

dialer

unit. When

required,

the

distance

between

the

power

supply and

dialer

unit

may

be

extended

by

the

use

ofa

suitable

4-conductor

cable

such

as

ordinary

JKT

wire.

This

power

supply

is

provided

with an

attached

3-wire

power

cord

(18

inches

long) equipped

with a

right

angle

parallel

blade

grounding

cap.

Both

the

power

cord

onthe

outlet

side

and the power supply

cover

are

light

olive

gray

color.

The

KS-19594 L4

cartridge

provides

the

record-

ing

tape

with

capacity

for

400

entries.

Marking

on the

tape

is

provided

for

alphabetical

grouping

of

the

names

(and telephone

numbers)

with a

single

red

line

for

in-

dexing

against

the

letters

of

the

alphabet

at

the bottom

of

the viewing window.

The

KS-19594 L5

cartridge

is

similar

to

the

KS-19594 L4

cartridge

but

provides

capacity

for

1000

entrieso

The

KS-19594 L6

cartridge

is

similar

to the

KS-19594 L5

cartridge,

except

that

the

alphabetical

grouping and

red

index

line

are

not

provided.

This

cartridge

permits

grouping of

entries

on an individual

basis

for

special

requirements.

TCI Library www.telephonecollectors.info

The

KS-19594 L14

cartridge

is

similar

to the

KS-19594 L6

line

is

num-

bered

consecutively

in

sequence

from

OPERATING

INSTRUCTIONS

(See

Fig.

Connecting the

Dial-in

Unit to the MAGICALL

Dialer

automatically

converts

the

Dialer

for

re

-

cording.

Any

previously

recorded

codes

and

numbers

may be

changed

by

dialing in a new

number

over

the

old one.

In

recording

a

sequence

of

numbers

containing

trunk,

access,

or

special

codes,

the

Dialer

can

be

stopped

by

placing an

interdigital

time

greater

than

1.

0

second

between

the

last

digit

of

the

trunk,

access,

or

special

code and the

remainder

of

the

number.

This

allows

the

user

to

receive

an

additional

dial

tone

before

proceeding

with

the

remaining

part

of the

se-

quence.

In

this

way,

the

correct

placing of a

call

is

made

independent of

the

time

delay

before

additional

dial

tones

are

obtained,

however

long

this

delay may

be.

4

To

record

a

number,

proceed

as

follows:

1.

Lift

the

door

in

front.

2.

Position

the

desired

blank

alphabetized

space

on

the

tape

between

the

red

markings

on the

writing

platform

by

operating

SELECTOR

3,

Write

name

and

number

in pen

or

DO

NOT

write

in

4.

Place

listing

between guide

lines

on viewing

window

by

operating

the

SELECTOR

WHEEL.

The

wheel

is

engaged

only when

it

is

de-

pressed.

This

prevents

it

from

turning

when

the

tape

drive

motor

is

running.

5.

Plug

Dial-in

Unit in

rear

of

exactly

as

it

would be

dialed

to

place

a

call,

including

area

codes,

making

certain

that

the WAIT light on

the

Dial-in

Unit

goes

out

before

dialing

each

digit.

NOTE:

DO

NOT FORCE

OR

RETARD THE DIAL

SPEED.

THIS

WILL

CAUSE A NUMBER

TO

BE

RECORDED INCORRECTLY.

8.

When

all

digits

in

the

telephone

number

have

been

dialed,

press

the STAR button.

9.

Disconnect

the

Dial-in

Unit.

If

more

than

is

to be

dialed

at

one

time,

it

is

not

necessary

to

If

an

must

first

be

used

to

(a)

Pick

If

a

tape

has

been

recorded

with

an

access

code

(such

as

"9"),

and night

lines

or

other

situations

sometimes

eliminate

the

need

for

using

such

a

code,

it

can

be

by-passed.

Simply

select

the

desired

party

and

press

the CALL button

before

liftingthe

telephone

receiver.

The

access

code

will

be

dialed

but

will

be

ineffectual

because

of

the

on-hook condition of

the

telephone

receiver.

When

the

code

has

been

dialed,

lift

the

receiver

to

get

a

dial

tone and

press

the

If

a

call

is

being

placed

from

a

key

telephone

or

switchboard

and

an

incoming

call

is

ringing

from

another

line,

the

MAGICALL

Dialer

can

be

stopped

in

order

to

answer

the

other

call

immediately.

This

is

done by moving

the

SELECTOR WHEEL

slightly

off

the

existing

or

tapping

the

If

it

is

not

to

assure

free

movement

of

parts,

lubricate

bearing

~d

sliding

surfaces

with Dow-Corning No. 560 silicone

oil

(or

equi-

valent). Use

lubricant

sparingly:

Excess

lubri-

cant

can

be

detrimental

to

future

operation

of

dialer

since

it

may

migrate

to

electrical

contacts

and/

or

attract

dust.
