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.

CONTROLS & CONNECTORS
TOP PANEL

(1) EAR Jack
This 2-conductor mini phone jack provides audio output for an external
earphone or optional Speaker/Mic (listed on previous page). When a plug
is installed in this jack the front panel loudspeaker is disabled.
(2) MIC Jack
This 2-conductor micro-mini phone jack accepts microphone input from
an external Speaker/Mic or other external source. When a plug is instal-
led in this jack the front panel microphone is disabled.
(3) DIAL Rotary Selector
•
This 20-position ro tary switch tunes the operating (or CTCSS tone) fre-
quency or selects the memory channels, according to which function is
selected by the keys on the front panel. This knob duplicates some of the
functions of the up and down arrow keys for operating convenience.
- 4 -

(4) VOL - ~ BAL Controls
The inner VOLume control adjusts receiver volume, and turns the set
OFF when set fully counterclockwise (into the click stop). The outer
BALance control adjust the relative balance of receiver audio for the
VHF and UHF bands, when receiving on both.
(5) SQL Control
This control sets the threshold level at which received signals (or noise)
open the noise
squelch. For prolonged battery life and maximum squelch
sensitivity, set this control from counterclockwise just to the point where
noise is silenced (and the BUSY/TX indicator on the front panel is off)
when the channel is clear.
(6) Antenna Jack
This BNC jack accepts the supplied YHA-28 rubber flex antenna, or
any other antenna designed to provide 50-ohm impedance on BOTl-1 the
2m and 70cm bands.

(7) Keypad
These twenty keys select the various operat ing features of the trans-
ceiver during reception. The lower six teen also generate DTMF (Dual
Tone Multi frequency) tone pairs during transmission. One or two beeps
sound
whenever a key is pressed (if the beeper is active). The label on
the face
of each key indicates its primary function, while the label above
it (if present) indicates an alternate function, activated by pressing the
f /M key at the lower right first, and then that key within three seconds.
When
referring to an alter n ate key function in this manual, we usually
show the alternate key label followed by the primary label in parenthe-
ses () . A primary key function is referred to only by the label on the
k~y face, except the arrow keys, which are just called the "arrow keys".
Remember to always press the f /M key first (momentarily, unless
otherwise · indicated) when you want to use an a lt ernate key function.
All key functions are described in the "Operation" sect ion, and s um -
ma
ri zed on the FT-4 70 Operator' s Quick Referenc e Card.

In some countries, one or more of the above may be supplied with the
transceiver. If not, contact your Yaesu dealer to purchase the desired
battery pack or case. We do not recommend use of any other type of
battery with the FT-4 70: using another type may affect your warranty.
The FN . B-9 through FNB-12, FNB-14 and FNB-17 may be recharged
either while attached to the transc eive r or separately, using the battery
chargers described on the following pages. Each Ni-Cd pack should be
fully charged before it is used wi th the transceiver for the first time.
Note that each of these packs requires a different wall charger:
N1 C -27B/C for the FNB-9, NC-28B / C for the FNB-10/-17, NC-18B/C for
FNB-11 or FNB-12, and NC-34B /C for FNB-14. Make certain that you
u se the correct c harger for each pack. The NC-29 Desktop Quic.k
Charger may be used with all of these Ni".'"Cd packs.
