GENERAL

1.01

This

part

provides testing

requirements

and

procedures

for

the

43

Basic

KSR

and

RO

Teleprinter.

1.02

The

information

in

this

part

is

intended

to

determine

if

th~

terminal

and

its

compo-

nents

are

operating

properly

and

will

continue

to

operate

for

extended

periods

under

normal

oper-

ating

conditions.

1.03

Endurance,

environmental

extreme

or

electrical

parameter

testing

information

is

not

provided in

this

part.

This

type

of

information

is

found

to

some

extent

in

Part

2,

Troubleshooting

and

is

used

to

isolate

and

correct

troubles

indicated

in

this

part.

1.04

The

testing

information

provided herein

should

normally

be

used

to

determine

if:

(a) A repaired

teleprinter

is

operating

properly

before

being

returned

to

a

customer

or

placed in service.

(b) A questionable

component

installed

in

the

teleprinter

operates

properly

or

requires

repair.

(c) A questionable teleprinter, in service

or

received

from

a

customer,

is

operating

properly

or

requires repair.

1.05

Following installation

or

routine

mainten-

ance calls

at

a

location,

either

the

testing

in

this

part

or

an

installation

checkout

using

the

HTO

manual should

be

performed

to

make

sure

the

teleprinter

is operational.

1.06

On

trouble

calls, a local

test

or

a

trouble

verification

test

under

the

direction

of

a

test

station

(if available) should

be

performed

to

isolate

the

trouble

within

or

to

the

teleprinter.

After

correction

of

a

trouble,

the

test

may

be

confined

to

the

specific

area

that

was failing.

1.07

The

checkout

routines

are

presented

in

table

form

with

test

conditions

arranged

in a specific sequence. A response is given

to

verify

the

test

condition

has

passed.

1.08

Always

perform

the

tests in

the

order

given.

The

test

steps are based

on

satis-

factory

results

of

all previous steps.

1.09

If

the

indicated

response is

not

obtained

in

any

step

of

a

test

procedure,

repeat

the

step

to

make sure

that

the

procedure

has

been

performed

properly.

If

the

results

are

still unsatis-

factory,

refer

to

Page 2-1, Troubleshooting.

1.10

Teleprinters

with

TAUs

or

with

no

Ter-

minal

Data

Unit

must

be

associated

with

locally developed

external

testing

arrangements

and

procedures

to

perform

actual

On-Line Tests.

If

test

station

is

remote,

a

copy

of

the

testing

procedure

should

be

available

at

the

test

station.

Note:

The

local

tests

specified

in

this

part

simu-

late

most

on-line

tests

for

these

teleprinters.

--1.11

Before

an

on-line

test

can

be

performed,

the

remote

testing

station

must

be

pro-

vided with advance details

about

the

teleprinter

under

test,

such as,

telephone

number,

type

of

terminal

(KSR

or

RO) (friction

or

sprocket)

option

exceptions

present,

speed,

etc.

391,

1-2

1.12

Before proceeding

with

the

checkout

procedure,

check

the

following:

(a) Is

teleprinter

connected

to

a properly

grounded

and

polarized ac

outlet?

(b) Are all cable

connectors

fully seated?

(c) Are

printer

paper

and

ribbon

properly

installed?

(d) Are

any

option

exceptions

present?

Refer

to

Manuals

368

(KSR)

and

373

(RO),

Page 2-1.

(Part

8

or

9)

Procedures in Off-Line Tests are based

on

standard

factory

furnished

options

being present.

If

option

exceptions

are present,

the

test

response will

be

as

shown

in

the

KSR

or

RO

Variable

to

simulate On-Line

Tests where

To

perform

these
