Thank

you

for

purchasing

the

new

TS-440S/44X

tran-

sceiver.

Please

read

this

instruction

manual

carefully

before

placing

your

transceiver

in

service.

This

unit

has

been

carefully

engineered

and

manufactured

to

rigid

quality

standard,

and

should

give

you

satisfactory

and

dependable

operation

for

many

years.

The

following

explicit

definitions

apply

in

this

manual:

1.

This

Instruction

Manual

covers

the

TS-440S

and

TS-44X,

both

with

and without

AT

Tuner)

unit.

When

there

are

differences

in

operation

separate

instructions

will

be

given

for

each

model.

Notes:

1.

A

may

provide

a

ground,

but

it

will

Making

a

is

important

for

preventing

dangers

such

as

and

for

emit-

ation.

Bury

and

connect

it

to

the

GND

terminal

of

the

TS-440S/44X.

A

thick

wire,

cut

as

short

as

possible,

should

be

used

for
