FT-470

2m/70cm

DUAL-BAND

FM

TRANSCEIVER

The

FT-470

is an

ultra

compact

FM

hand-held

providing

up

to

five

watts

of

RF

power

on the

2m

and 70cm

amateur

bands. A

die-cast

rear

case

and

rubber

gasket

seals

around

controls

and

connectors

assure

years

of

reliability,

while

multi-tasking

microprocessor

programming

provides

a

new

level

operating

flexibility.

Unique

features

include

s

imultaneous

reception

on

both

bands, a

CTCSS

(Continuous

Tone

Controlled

Squelch

System)

with

paging

features,

and

10-memory

DTMF

Autodialler,

all

built-in

as

standard.

Twenty

multi-

function

keys

provide

the

ultimate

in

programmability

of

21

freely

tunable

memories

and

two

vfos

on

each

band.

All

memories

store

repeater

shifts

or

separate

tx

/

rx

frequencies,

CTCSS

tones and tone

encode/decode

selections,

with

one

instant-recall

call

channel

memory

and

two

special

purpose

memories

for

limited

subband

tuning/scanning.

Busy

channel

band,

selective

memory

and

alternating

band

scanning

are

provided

along

with

priority

channel

monitoring;

!MHz

up/down

stepping;

ARS

(automatic

repeater

shift)

when

tuned

to

repeater

subbands,

plus

a

top

panel

rotary

dial

for

memory

and

frequency

selection.

The

keypad

serves

as

a

DTMF

encoder

or

Autodialler

selector

during

transmission.

The

multi-tasking

cpu

allows

scanning and

priority

monitoring

on

both

bands

simultaneously.

The

liquid

crystal

display

shows

5-

~

frequency

digits

on

both

bands,

memory

selection,

CTCSS

tone

frequency

while

setting,

paging

status

when paged

by

a

CTCSS

tone, and

includes

a

bargraph

S/PO

meter.

Yaesu's

power

saver

system

can

be

set

by

the

operator

for

optimum

sampling/standby

ratio,

or

can

be

turned

off

for

packet.

And

our

new

APO

(Automatic

Power

Off)

system shuts

off

the

transceiver

to

avoid

dead

batteries

if

you

doze

off

or

are

called

away

unexpectedly.

Operation

under

difficult

conditions

is eased

by

illumination

of

the

display

and

translucent

keypad

and

diatonically

assigned

function-related

keypad

beeps.

Please

read

this

manual

carefully

to

gain

a·

clear

understanding

of

the

features

of

the

FT-470.
