GENERAL DESCRIPTION
The FT-270R is a compact, high-performance FM hand-held providing up to five watts of
RF power and wealth of convenient features for the 2-meter amateur band.
New and exciting features of the FT-270R are Enhanced Paging and Code Squelch (EPCS),
that allows you to page a particular station and only receive calls from that station, if
desired; and a security Password feature, that will allow you to turn on and operate your
transceiver only after you enter your Password.
Additional features include a convenient access key for Yaesu’s WIRES™ (Wide-coverage
Internet Repeater Enhancement System), a transmit Time-Out Timer (TOT), Automatic Power-
Off (APO), Automatic Repeater Shift (ARS), Yaesu’s exclusive ARTS™ (Auto-Range Tran-
sponder System) which “beeps” the user when you move out of communications range
with another ARTS™ equipped station, plus provision for reduction of the TX deviation in
areas of high channel congestion. And an RF squelch circuit allows the owner to set the
squelch to open at a programmable setting of the S-Meter, thus reducing guesswork in
setting the squelch threshold.

FT-270R OPERATING MANUAL8
ANTENNA INSTALLATION
The supplied antenna provides good results over the entire
frequency range of the transceiver. However, for enhanced
reception on certain non-Amateur frequencies, you may wish
to connect an antenna designed specifically for that frequency
range, as the supplied antenna is necessarily a compromise
outside the Amateur band, and cannot be expected to provide
high performance at all frequencies.
To install the supplied antenna, hold the bottom end of the
antenna, then screw it onto the mating connector on the trans-
ceiver until it is snug. Do not over-tighten by use of extreme
force.
Notes:
Never transmit without having an antenna connected.
When installing the supplied antenna, never hold the upper part of the antenna while
screwing it onto the mating connector on the transceiver.
If using an external antenna for transmission, ensure that the SWR presented to the
transceiver is 1.5:1 or lower, to avoid excessive feedline loss.
INSTALLATION OF FNB-83 BATTERY PACK
The FNB-83 is a high-performance Ni-MH battery providing high capacity in a compact
package. Under normal use, the FNB-83 may be used for approximately 300 charge cycles,
after which operating time may be expected to decrease. If you have an old battery pack
which is displaying capacity which has become diminished, you should replace the pack
with a new one.
Installation of the battery is easy and quick:
Insert the battery pack into the battery compart-
ment on the back of the radio while tilting the
Belt Clip outward, then
close the Battery Pack
Latch until it locks in
place with a “Click.”
To remove the battery,
turn the radio off and
remove any protective
cases. Open the Battery
Pack Latch on the bottom of the radio, then slide the battery downward and out from
the radio while tilting the Belt Clip out of the way.

FT-270R OPERATING MANUAL 9
BATTERY CHARGING
If the battery has never been used, or its charge is depleted, it may be charged by connect-
ing the PA-48 Battery Charger, as shown in the illustration, to the SBH-13 DC jack.
If only 12 ~ 16 Volt DC power is available, the optional E-DC-5B DC Cable (with its cigarette
lighter plug) or E-DC-6 DC Cable (plug and wire only) may also be used for charging the
battery.
A fully-discharged pack will be charged completely in 3.5 - 4 hours. Disconnect the PA-48
from the SBH-13 DC jack and the AC line outlet.
INSTALLATION OF ACCESSORIES
Important Note
The PA-48 is not designed to power the transceiver for operation (reception or trans-
mission).
Do not leave the PA-48 connected to the transceiver for continuous periods in excess
of 24 hours. Long term overcharging can degrade the Ni-MH battery pack and signifi-
cantly shorten its useful life.
Please be advised that the PA-48 may contribute noise to TV and radio reception in the
immediate vicinity, so we do not recommend its use adjacent to such devices.
LOW BATTERY INDICATION
As your battery discharges during use, the voltage will gradually become lower. When
the battery voltage is becoming too low for reliable operation,
the “ ” icon will blink on the LCD display, indicating that the
battery pack must be recharged before further use.
Avoid recharging Ni-MH batteries before the “ ”indicator is
observed, as this can degrade the charge capacity of your Ni-MH battery pack.

BELT CLIP INSTALLATION
Connect the hanger to the rear of the FT-270R, with the notch pointing directly up,
using the supplied screw (Figure 1). Use only the screw included with the clip to mount
the clip to the back of the FT-270R.
Clip the Quick-Draw Belt Clip onto your belt (Figure 2).
To install the FT-270R into the Quick-Draw Belt Clip, align the hanger with the Quick-
Draw Belt Clip, and slide the FT-270R into its slot until a click is heard (Figure 3).
To remove the FT-270R from the Quick-Draw Belt Clip, rotate the FT-270R 180 de-
grees, then slide the FT-270R out from the Quick-Draw Belt Clip (Figure 4).
INSTALLATION OF ACCESSORIES
INSTALLATION OF FBA-25A ALKALINE BATTERY CASE (OPTION)
The optional FBA-25A Battery Case allows operation of the FT-270R using six “AA” size
Alkaline batteries.
When installing batteries, insert the (–) end first, then press in the (+) end so the battery
snaps into place. Always replace all six batteries at the same time, paying attention to the
polarity indicated inside the case.
The FBA-25A must not be used with rechargeable cells. The FBA-25A does not contain
the thermal and over-current protection circuits (provided in the “FNB” series of Ni-MH
Battery Packs) required when utilizing Ni-Cd and Ni-MH cells.
Note that the power output and battery life will be much shorter when using Alkaline AA
cells. They should be considered an emergency backup power source only, for this reason.

FT-270R OPERATING MANUAL 11
The FT-270R may be used for Packet operation, using the optional CT-91 Microphone
Adapter (available from your Yaesu dealer) for easy interconnection to commonly-avail-
able connectors wired to your TNC. You may also build your own cable, using a four-
conductor miniature phone plug, per the diagram below.
The audio level from the receiver to the TNC may be adjusted by using the VOL knob, as
with voice operation. The input level to the FT-270R from the TNC should be adjusted at
the TNC side; the optimum input voltage is approximately 5 mV at 2000 Ohms.
Be sure to turn the transceiver and TNC off before connecting the cables, so as to prevent
voltage spikes from possibly damaging your transceiver.
When you are operating on Packet, switch the Receive Battery Saver OFF, as the “sleep”
cycle may “collide” with the beginning of an incoming Packet transmission, causing your
TNC not to receive the full data burst. See page 60 for details regarding Battery Saver
setup.

FT-270R OPERATING MANUAL12
Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many
features of the FT-270R. I know you’re anxious to get on the air, but I encour-
age you to read the “Operation” section of this manual as thoroughly as
possible, so you’ll get the most out of this fantastic new transceiver. Now. . .let’s get
operating!
SWITCHING POWER ON AND OFF
Be sure the Battery Pack is installed, and that the battery is fully charged. Connect the
antenna to the top panel ANTENNA jack.
Rotate the top panel’s VOL/PWR knob (inner knob)
out of the click-stop to turn on the radio. The current
DC supply voltage will be indicated on the display for 2
seconds. After this 2 second interval, the display will
resume its normal indication of the operating frequency.
To turn the radio off, turn the VOL/PWR knob fully
counter-clockwise into the click stop position.
ADJUSTING THE AUDIO VOLUME LEVEL
Rotate the VOL/PWR knob (inner knob) to adjust the re-
ceiver audio to a comfortable listening level, using the back-
ground noise as a reference. Clockwise rotation increases
the volume level.

FT-270R OPERATING MANUAL 13
OPERATION
SQUELCH ADJUSTMENT
To set the squelch, press the [F/L] key, followed by the MONI switch just below the
PTT switch on the left side of the transceiver.
Now rotate the DIAL (outer knob) to find the lowest
setting (“LVL 1LVL 1
LVL 1LVL 1
LVL 1” through “LVL 15LVL 15
LVL 15LVL 15
LVL 15”) that will just
silence the background noise. Do not use a higher set-
ting than necessary, or sensitivity to weak incoming
signals will be degraded.
Press the PTT switch momentarily when you’ve made
the new setting; this will return you to normal operation (without having transmitted).
1) A special “RF Squelch” feature is provided on this radio. This feature
allows you to set the squelch so that only signals exceeding a certain S-meter
level will open the squelch. See page 18 for details.
2) If you’re operating in an area of high RF pollution, you may need to consider “Tone
Squelch” operation using the built-in CTCSS Decoder. This feature will keep your radio
quiet until a call is received from a station sending a carrier which contains a matching
(subaudible) CTCSS tone. Or, if your friends have radios equipped with DCS (Digital
Coded Squelch) like your FT-270R has, try using that mode for silent monitoring of busy
channels.
FREQUENCY NAVIGATION
The FT-270R will initially be operating in the “VFO” mode, a channelized system which
allows free tuning throughout the currently-selected operating band.
Three basic frequency navigation methods are available on the FT-270R:
1) Tuning Dial
Rotation of the DIAL (outer knob) allows tuning in the pre-programmed steps established
for the current operating band. Clockwise rotation of the DIAL causes the FT-270R to be
tuned toward a higher frequency, while counter-clockwise
rotation will lower the operating frequency.
If you press the [F/L] key momentarily, then rotate the DIAL,
frequency steps of 1 MHz will be selected. This feature is
extremely useful for making rapid frequency excursions over
the wide tuning range of the FT-270R.

The desired operating frequency may be entered directly from the keypad. The first “1” in
the frequency does not need to be entered, as it is “assumed” by the microprocessor.
To enter a frequency directly, just key in the 10 MHz, 1 MHz, and the kHz digits.
Examples:To enter 146.560 MHz, press [4] [6] [5] [6] [0]
To enter 146.5625 MHz (12.5 kHz steps), [4] [6] [5] [6] [2]
3) Scanning
Press and hold in either the [(MHz)] or [(MHz)] key for
one second to initiate upward or downward scanning, re-
spectively (Manual VFO Scan).
For scanning within a limited sub-band range, from the VFO
mode, press and hold in the [6(A/N)] key for one second to
begin scanning toward a higher frequency within the previ-
ously-defined sub-band (Programmed VFO Scan). Details
regarding sub-band setup may be found on page 37.
If you wish to reverse the direction of the scan (i.e. toward a
lower frequency, instead of a higher frequency), just rotate
the DIAL one click in the counter-clockwise direction while
the FT-270R is scanning. The scanning direction will be
reversed. To revert to scanning toward a higher frequency
once more, rotate the DIAL one click clockwise.
The scanner will stop when it receives a signal strong enough to break through the Squelch
threshold. The FT-270R will then hold on that frequency according to the setting of the
“RESUME” mode (Set Mode Item 32: RESUMERESUME
RESUMERESUME
RESUME). Press the PTT switch momentarily to
cancel the scanning. This only stops the scan; it does not cause transmission to occur. See
page 38 for details regarding Scan Operation.

OPERATION
TRANSMISSION
Once you have set up an appropriate frequency inside the 144 MHz Amateur band on
which the FT-270R can transmit, you’re ready to go on the air! These are the most basic
steps; more advanced aspects of transmitter operation will be discussed later.
To transmit, press the PTT switch, and speak into the
front panel microphone (located in the lower left-hand
corner of the speaker grille) in a normal voice level. The
TX/BUSY indicator will glow red during transmission.
To return to the receive mode, release the PTT switch.
During transmission, the relative power level will be
indicated on the bar graph at the bottom of the LCD;
full scale deflection confirms “High Power” operation, while
deflection of two bars indicates “Low Power” operation. Five
bars indicate “Medium Power” operation. Additionally, the
“LOW” icon will appear at the bottom of the display while oper-
ating on the “Low Power” and “Medium Power” settings.
1) If you’re just talking to friends in the immediate area,
you’ll get much longer battery life by switching to Low
Power operation, described in the next chapter. And don’t
forget: always have an antenna connected when you transmit.
2) Transmission is possible only on the 144 MHz amateur band.
Changing the Transmitter Power Level
To change the power level:
Press the [F/L] key, then press the [3(LOW)] key. The
LCD shows the current power output level.
Rotate the DIAL knob to select the desired power out-
put level. Available selections are “HIGHHIGH
HIGHHIGH
HIGH” (5 W),
“MIDMID
MIDMID
MID” (2 W), and “LOWLOW
LOWLOW
LOW” (0.5 W).
When you have made your choice, press the PTT switch
to save the new setting and return to normal operation.
1) The FT-270R is smart! When you store memories, you can store the power
output settings separately in each memory, so you don’t waste battery power
when using very close-in repeaters!
2) When you are operating on the “Low” or “Medium” power setting, you can press the
[F/L] key, then press the PTT switch, to cause the FT-270R to transmit (temporarily) on
High power. After one transmission, the power level will revert to the previously-selected
(“Low” or “Medium” power) setting.

REPEATER OPERATION
Repeater stations, usually located on mountaintops or other high locations, provide a
dramatic extension of the communication range for low-powered hand-held or mobile trans-
ceivers. The FT-270R includes a number of features which make repeater operation simple
and enjoyable.
REPEATER SHIFTS
The FT-270R has been configured, at the factory, with the repeater shift set to 600 kHz.
Depending on the part of the band in which
you are operating, the repeater shift may be
either downward (–) or upward (+), and one of
these icons will appear at the top of the LCD
when repeater shifts have been enabled.
AUTOMATIC REPEATER SHIFT (ARS)
The FT-270R provides a convenient Automatic Repeater Shift feature, which causes the
appropriate repeater shift to be applied automatically whenever you tune into the desig-
nated repeater sub-bands in your country. These sub-bands are shown below.
If the ARS feature does not appear to be working, you may have accidentally disabled it.
To re-enable ARS:
1. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 4: ARSARS

MANUAL REPEATER SHIFT ACTIVATION
If the ARS feature has been disabled, or if you need to set a repeater shift direction other
than that established by the ARS, you may set the direction of the repeater shift manually.
To do this:
1. Press the [F/L] key, then press the [4(RPT)] key to enable selection of the repeater
shift direction.
2. This provides a “short-cut” to Set Mode Item 35: RPT.MODRPT.MOD
RPT.MODRPT.MOD
RPT.MOD.
3. Rotate the DIAL knob to select the desired shift among “RPT.–RPT.–
RPT.–RPT.–
RPT.–,”
“RPT.+RPT.+
RPT.+RPT.+
RPT.+,” and “RPT.OFFRPT.OFF
RPT.OFFRPT.OFF
RPT.OFF.”
4. When you have made your selection, press the PTT switch to save the new setting and
return to normal operation.
If you make a change in the shift direction, but still have Automatic Repeater
Shift still engaged (see previous section), when you change frequency (by
rotating the DIAL knob, for example) the ARS will over-ride your manual
setting of the shift direction. Turn ARS off if you do not wish this to happen.
If you make a change in the repeater shift on a memory channel that you already stored, the
radio will consider this a “temporary” change unless you store the memory once more, this
time with the desired repeater shift engaged.
Changing the Default Repeater Shifts
If you travel to a different region, you may need to change the default repeater shift so as
to ensure compatibility with local operating requirements.
To do this, follow the procedure below:
1. Press the [F/L] key, then press the [0(SET)] key to enter the Set
mode.
2. Rotate the DIAL knob to select Set Mode Item 41: SHIFTSHIFT

5. When you have made your selection, press the PTT switch to save the new setting
and return to normal operation.
If you just have one “odd” split that you need to program, don’t change the
“default” repeated shifts using this Set Mode Item. Enter the transmit and
receive frequencies separately, as shown on page 29.

Checking the Repeater Uplink (Input) Frequency
It often is helpful to be able to check the uplink (input) frequency of a repeater, to see if the
calling station is within direct (“Simplex”) range.
To do this, just press the [REV(HOME)] key. You’ll notice
that the display has shifted to the repeater uplink frequency.
Press the [REV(HOME)] key again to cause operation to
revert to normal monitoring of the repeater downlink (out-
put) frequency. While you are listening on the input fre-
quency to the repeater using the [REV(HOME)] key, the
repeater offset icon will blink.
The configuration of this key may be set either to “RV” (for checking the input fre-
quency of a repeater), or “HM” (for instant switching to the “Home” channel for the
band you are operating on). To change the configuration of this key, use Set Mode Item
33: REV/HM. See page 77.
VFO SPLIT MODE
For working on repeaters with odd splits, or communicating with astronauts on orbiting
space vehicles, it may be necessary to use non-standard splits between the receive and
transmit frequency. If the application is infrequent enough not to warrant the dedication of
a memory channel for this purpose, the “VFO Split” mode may be used. Here is the proce-
dure for going Split:
1. Press the [VFO(PRI)] key, as needed, to select VFO-A. Set VFO-A for the desired
receiving (downlink) frequency (e.g.145.800 MHz).
2. Now press the [VFO(PRI)] key, and set VFO-B for the desired transmit (uplink) fre-
quency (e.g. 144.490 MHz).
3. Press the [VFO(PRI)] key once more to re-establish VFO-A as the “Main” (receive)
VFO.
4. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
5. Rotate the DIAL to select Set Mode Item 50: VFO.SPLVFO.SPL
VFO.SPLVFO.SPL
VFO.SPL.
6. Press the [F/L] key, then rotate the DIAL to set this function
“VSP. ONVSP. ON
VSP. ONVSP. ON
VSP. ON.”
7. Press the PTT switch once to save the new setting and exit to
normal operation.
8. You will now be operating in the Split mode. When you press
the PTT switch to transmit, you will observe that VFO-A and
VFO-B will reverse positions. The VFO selection indicator “-b-” will blink while the
transceiver is transmitting, this means that the VFO Split feature is now activated.

9. If you need to modify the VFO-B (transmit) frequency (for Doppler Shift correction,
etc.), just press the [VFO(PRI)] key, then make the necessary change, then press
[VFO(PRI)] key once more to restore VFO-A to the “receive VFO” position.
10. When you have finished with Split operation, re-enter the Set mode, and change Set
Mode Item 50: VFO.SPLVFO.SPL
VFO.SPLVFO.SPL
VFO.SPL to “VSP.OFFVSP.OFF
VSP.OFFVSP.OFF

A split frequency pair set up via the VFO Split feature cannot be stored directly into
memory. You can, however, store odd frequency pairs using a different (slightly simpler)
procedure. See page 29.

FT-270R OPERATING MANUAL 23
CTCSS/DCS/EPCS OPERATION
CTCSS OPERATION
Many repeater systems require that a very-low-frequency audio tone be superimposed on
your FM carrier in order to activate the repeater. This helps prevent false activation of the
repeater by radar or spurious signals from other transmitters. This tone system, called
“CTCSS” (Continuous Tone Coded Squelch System), is included in your FT-270R, and is
very easy to activate.
CTCSS setup involves two actions: setting the Tone Mode and then setting of
the Tone Frequency. These actions are set up by using the [1(SQ TYP)] key
and [2(CODE)] keys.
1. Press the [F/L] key, then press the [1(SQ TYP)] key to enable selection of the CTCSS/
DCS/ECS mode.
2. Rotate the DIAL knob so that “TONETONE
TONETONE
TONE” indication appears on
the display; this activates the CTCSS Encoder, for access to
repeaters requiring a CTCSS tone.
3. Rotation of the DIAL knob one more “click” in step “2” above
will cause the “TSQLTSQL
TSQLTSQL
TSQL” notation to appear. When “TSQLTSQL
TSQLTSQL
TSQL” is
displayed, this means that the Tone SQueLch system is active,
which mutes your FT-270R’s receiver until it receives a call from
another radio sending out a matching CTCSS tone. This can
help keep your radio quiet until a specific call is received, which may be helpful while
operating in congested areas of the band.
1) You may notice a “REV TN” indication on the display while you rotate
the DIAL knob in this step; this means that the Reverse Tone Squelch
system is active, which mutes your FT-270R’s receiver (instead of opening
the squelch) when it receives a call from the radio sending a matched
CTCSS tone. The “ ” icon will blink on the display when the Reverse Tone
Squelch system is activated.
2) You may notice the “DCS” and “ECS” indications on the display while you rotate
the DIAL knob still more. We’ll discuss the Digital Code Squelch system (for “DCS”)
and Enhanced Paging & Code Squelch (for “ECS”) later.
4. When you have made your selection of the CTCSS tone mode, press the PTT switch
to save the new setting.
5. Press the [F/L] key, then press the
[2(CODE)] key to enable adjustment of
the CTCSS fre-
quency.
6. Rotate the DIAL
knob until the dis-
play indicates the Tone Frequency you
need to be using (ask the repeater owner/

7. When you have made your selection, press the [F/L] key momentarily to save the new
settings and exit to normal operation. This is different than the usual method of restor-
ing normal operation, and it applies only to the configuration of the CTCSS/DCS
frequencies.
Your repeater may or may not re-transmit a CTCSS tone - some systems just
use CTCSS to control access to the repeater, but don’t pass it along when
transmitting. If the S-Meter deflects, but the FT-270R is not passing audio,
repeat steps “1” through “4” above, but rotate the DIAL so that “TSQ” disappears - this
will allow you to hear all traffic on the channel being utilized.
DCS OPERATION
Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more
advanced tone system which generally provides more immunity from false paging than
does CTCSS. The DCS Encoder/Decoder is built into your FT-270R, and operation is very
similar to that just described for CTCSS. Your repeater system may be configured for
DCS; if not, DCS is frequently quite useful in Simplex operation if your friend(s) use
transceivers equipped with this advanced feature.
Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and that
you select a tone code.
1. Press the [F/L] key, then press the [1(SQ TYP)] key to enable selection of the CTCSS/
DCS/ECS mode.
2. Rotate the DIAL knob until the “DCSDCS
DCSDCS
DCS” indication appears on the
display; this activates the DCS Encoder/Decoder.
3. Press the PTT switch to save the new setting.
4. Press the [F/L] key, then press the [2(CODE)] key to enable adjustment of the DCS code.
5. Rotate the DIAL knob to select the desired DCS Code (a three-digit number). Ask the
repeater owner/operator if you don’t
know DCS Code; if
you are working
simplex, just set up
the DCS Code to
be the same as that used by your friend(s).
6. When you have made your selection,
press the [F/L] key momentarily to save
the new settings and exit to normal opera-
tion.

FT-270R OPERATING MANUAL 25
CTCSS/DCS/EPCS OPERATION
Remember that the DCS is an Encode/Decode system, so your receiver will
remain muted until a matching DCS code is received on an incoming trans-
mission. Switch the DCS off when you’re just tuning around the band!
TONE SEARCH SCANNING
In operating situations where you don’t know the CTCSS or DCS tone being used by
another station or stations, you can command the radio to listen to the incoming signal and
scan in search of the tone being used. Two things must be remembered in this regard:
You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
Some repeaters do not pass the CTCSS tone; you may have to listen to the station(s)
transmitting on the repeater uplink (input) frequency in order to allow Tone Search
Scanning to work.
To scan for the tone in use:
1. Set the radio up for either CTCSS or DCS Decoder operation (see the previous discus-
sions). In the case of CTCSS, “ ” will appear on the display; in the case of DCS,
“” will appear on the display.
2. Press the [F/L] key, then press the [2(CODE)] key.
3. Press and hold in the [(MHz)] or [(MHz)] key for one sec-
ond to start scanning for the incoming CTCSS or DCS tone/
code.
4. When the radio detects the correct tone or code, it will halt on
that tone/code, and audio will be allowed to pass. Press the [F/L]
key to lock in that tone/code, then press the [F/L] key again to
exit to normal operation.
If the Tone Scan feature does not detect a tone or code, it will continue to scan
indefinitely. When this happens, it may be that the other station is not sending
any tone. You can press the PTT switch to halt the scan at any time.
You also can press the MONI key during Tone Scanning to listen to the (muted) signal from
the other station. When you release the MONI key, Tone Scanning will resume after about
a second.
Tone Scanning works either in the VFO or Memory modes.

FT-270R OPERATING MANUAL26
EPCS (ENHANCED PAGING & CODE SQUELCH)
The FT-270R includes an Enhanced CTCSS tone encoder/decoder and a dedicated micropro-
cessor providing paging and selective calling features. This allows you to place a call to a specific
station (Paging), and to receive calls of your choice directed only to you (Code Squelch).
The paging and code squelch systems use two pairs of (alternately switched) CTCSS tones
which are stored in the pager memories. Basically, your receiver remains silent until it
receives the CTCSS tone pair that matches those stored in the Receiving Pager Memory.
The squelch then opens so the caller is heard, and the paging ringer immediately sounds, if
activated. When you close the PTT switch to transmit, the CTCSS tone pair which is
stored in the Transmitting Pager Memory will be transmitted automatically.
On the paged radio, the squelch will close automatically after the incoming page ends.
Storing the CTCSS Tone Pairs for EPCS Operation
1. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 18: ECS.CDRECS.CDR

for the Receiving CTCSS Tone Pair or Set Mode Item 19:
ECS.CDTECS.CDT
ECS.CDTECS.CDT
ECS.CDT for the Transmitting CTCSS Tone Pair.
3. Press the [F/L] key momentarily to enable adjustment of this Set
Mode Item.
4. Rotate the DIAL knob to set the CTCSS Tone number which
corresponds to the first tone of the CTCSS Tone Pair.
5. Press the [(MHz)] or [(MHz)] key, then rotate the DIAL
knob to set the CTCSS Tone number which corresponds to the
second tone of the CTCSS Tone Pair.
6. Press the PTT switch to save the new setting and exit to normal
operation.
The FT-270R does not recognize the order of the 1st
tone and the 2nd tone. In other words, for example, the
FT-270R considers both CTCSS pairs “10, 35” and “35, 10” to be identical.

BANK10.” Each Memory Bank
can be assigned up to 200 channels from the “standard” memory channels.
10 “Weather Broadcast” Channels.
MEMORY STORAGE
1. Select the desired frequency, while operating in the VFO mode. Be sure to set up any
desired CTCSS or DCS tones, as well as any desired repeater offset, now. The power
level may also be set at this time, if you wish to store it.
2. Press and hold in the [MR/MW(SKIP)] key for one second.
3. Within ten seconds of releasing the [MR/MW(SKIP)] key, you need to make a deci-
sion regarding channel storage. The microprocessor will automatically select the next-
available “free” channel (a memory register on which no data has been stored), so you
may not wish to make any change; if this is the case, proceed to step 4. If you wish to
select a different channel number into which to store the data, rotate the DIAL knob to
select the desired memory channel. You may jump 10 memory channels, if you’re in a
hurry (11 21 31 …) by pressing the [VFO(PRI)] key (multiple times, if necessary).
4. Press the [MR/MW(SKIP)] key once more to store the frequency into memory.
5. You still will be operating in the “VFO” mode, so you may now enter other frequencies,
and store them into additional memory locations, by repeating the above process.
Storing Independent Transmit Frequencies (“Odd Splits”)
All memories can store an independent transmit frequency, for operation on repeaters with
non-standard shift. To do this:
1. Store the receive frequency using the method already described under MEMORY
STORAGE (it doesn’t matter if a repeater offset is active).
2. Tune to the desired transmit frequency, then press and hold in the [MR/MW(SKIP)]
key for one second.
3. Within ten seconds of releasing the [MR/MW(SKIP)] key, rotate the DIAL knob to
select the same memory channel number as used in step “1” above.
4. Press and hold in the PTT switch. Then while holding the PTT switch in, momentarily
press the [MR/MW(SKIP)] key once more. (This does not key the transmitter).
1) The “Odd Splits” feature permits setting TONE/DCS indi-
vidually for transmit and receive. Briefly, press the [F/L] key,
and then press the [2(CODE)] key. Rotate the DIAL knob to
select the TONE or DCS for receive. You can confirm the Transmit and
receive TONE/DCS by alternately pressing of the [REV(HOME)] key.

FT-270R OPERATING MANUAL36
The FT-270R allows you to scan just the memory channels, the entire operating band, or a
portion of that band. It will halt on signals encountered, so you can talk to the station(s) on
that frequency, if you like.
Scanning operation is basically the same in each of the above modes. Before you begin,
take a moment to select the way in which you would like the scanner to resume scanning
after it halts on a signal.
Setting the Scan-Resume Technique
Three options for the Scan-Resume mode are available:
BUSYBUSY
BUSYBUSY
BUSY: In this mode, the scanner will halt on a signal it encounters. Two seconds after the
carrier has dropped because the other station(s) ceased transmission, the scanner
will resume. In the case of constant-carrier signals like Weather Station broad-
casts, the scanner will likely remain on this frequency indefinitely.
HOLDHOLD
HOLDHOLD
HOLD: In this mode, the scanner will halt on a signal it encounters. It will not restart
automatically; you must manually re-initiate scanning if you wish to resume.
TIMETIME
TIMETIME
TIME: In this mode, the scanner will halt on a signal it encounters, and will hold there for
five seconds. If you do not take action to disable the scanner within that time
period, the scanner will resume even if the stations are still active.
To set the Scan-Resume mode:
1. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 32: RESUMERESUME

How to Skip (Omit) a Channel during Memory Scan Operation
As mentioned previously, some continuous-carrier stations like a Weather Broadcast sta-
tion will seriously impede scanner operation if you are using the “Carrier Drop” Scan-
Resume mode, as the incoming signal will not pause long enough for the transceiver to
resume scanning. Such channels may be “Skipped” during scanning, if you like:
1. Recall the Memory Channel to be skipped during scanning.
2. Press the [F/L] key, then press the [MR/MW(SKIP)] key to enter the “Skip” channel-
selection mode.
3. Rotate the DIAL knob so as to select “SKIPSKIP
SKIPSKIP
SKIP.” The current Memory
Channel will now be ignored during scanning. The “ONLYONLY
ONLYONLY
ONLY” se-
lection is used for “Preferential Memory Scan,” described in the
next section.
4. When you have made your selection, press the PTT switch to save the setting and exit
to normal operation.
When you recall the “skipped” memory channel manually, a small
“” icon will appear at the left of the memory channel number, indi-
cating it is to be ignored during scanning.
To re-institute a channel into the scanning loop, select “OFFOFF
OFFOFF
OFF” in step 3 above (the “Skipped”
channel will, of course, still be accessible via manual channel selection methods using the
DIAL knob in the MR mode, whether or not it is locked out of the scanning loop).

PROGRAMMABLE (BAND LIMIT) MEMORY SCAN (PMS)
This feature allows you to set sub-band limits for either scanning or manual VFO operation.
For example, you might wish to set up a limit (in North America) of 144.300 MHz to 148.000
MHz so as to prevent encroachment into the SSB/CW “Weak Signal” portion of the band
below 144.300 MHz. Here’s how to do this:
1. Set the radio to the VFO mode by pressing the [VFO(PRI)] key, if necessary.
2. Using the techniques learned earlier, store (per the above concept) 144.300 MHz into
Memory Channel #L1 (the “L” designates the Lower sub-band limit).
3. Likewise, store 148.000 MHz into Memory Channel #U1 (the “U” designates the
Upper sub-band limit).
4. Confirm the radio is in the VFO mode, press and hold in the [VFO(PRI)] key for one
second, and rotate the DIAL knob to select the desired PMS frequency pair (PMSxxPMSxx
PMSxxPMSxx
PMSxx),
then press the [VFO(PRI)] key.
5. Now, press and hold in the [MR/MW(SKIP)] key for one second to initiate Program-
mable (Band Limit) Memory Scan. Scanning will now be limited within the just-pro-
grammed range.
6. 10 pairs of Band Limit memories, labeled L1/U1 through L10/U10 are available. You
therefore can set upper and lower operation limits in multiple segments on the band, if
you like.

below the current frequency, plus the current frequency itself).
Two basic operating modes for Smart Search are available:
SINGLESINGLE
SINGLESINGLE
SINGLE: In this mode, the transceiver will sweep the current band once in each direction
starting on the current frequency. All channels where activity is present will be
loaded into the Smart Search memories; whether or not all 31 memories are
filled, the search will stop after one sweep in each direction.
CONTCONT

The ARTS™ feature uses DCS signaling to inform both parties when you and another
ARTS™-equipped station are within communications range. This may be particularly use-
ful during Search-and Rescue situations, where is important to stay in contact with other
members of your group.
Both stations must set up their DCS codes to the same code number, then activate their
ARTS™ feature using the command appropriate for their radio. Alert ringers may be acti-
vated, if desired.
Whenever you push the PTT switch, or every 25 (or 15) seconds

FT-270R OPERATING MANUAL 55
The FT-270R allows you to utilize a DTMF (Dual-Tone, Multi-Frequency) tone encoder/
decoder, with a dedicated microprocessor providing paging and selective calling features
now that you've installed the optional FTD-7 DTMF Paging Unit. This capability allows
you to make a call to a specific station (Paging), and to receive calls of your choice di-
rected only to you (Code Squelch).
The paging and code squelch systems use 3-digit numeric codes (000 - 999) which are
stored in the DTMF Pager Memories. Basically, your receiver remains silent until it re-
ceives the 3-digit DTMF pager code that matches those stored in the DTMF Pager Memory.
The squelch then opens so the caller is heard, and the LCD displays the 3-digit DTMF
pager code which was received. Also, the paging ringer immediately sounds, if the Bell
function is activated. When you close the PTT switch to transmit, the 3-digit DTMF pager
code which is stored in the last selected DTMF Pager Memory register will be transmitted
automatically.
On the paged radio, the squelch will close automatically five seconds after the incoming
page ends (you may now resume DTMF Pager operation).
Storing the 3-digit code for the DTMF Pager Operation
1. Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 57: PAG.CODPAG.COD

7. Press the [F/L] key momentarily to accept the first digit and
move to the second digit of the 3-digit DTMF pager code.
8. Repeat the previous steps until you have completed the 3-digit
DTMF pager code.
9. Press the [REV(HOME)] key to toggle the decoder “on” and
“off.” When the decoder is set to “on,” the “----------” notation ap-
pears between the DTMF pager memory register number and the
3-digit DTMF pager code; for example, “P2P2
P2P2
P2------123-123
-123-123
-123.”
The 3-digit DTMF pager code which does not have the “----------” no-
tation is used for encode only.

RECEIVE BATTERY SAVER SETUP
An important feature of the FT-270R is its Receive Battery Saver, which “puts the radio to
sleep” for a time interval, periodically “waking it up” to check for activity. If somebody is
talking on the channel, the FT-270R will remain in the “active” mode, then resume its
“sleep” cycles. This feature significantly reduces quiescent battery drain, and you may
change the amount of “sleep” time between activity checks using the Set Mode:
1. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 37: RXSAVERXSAVE

5. When you have made your selection, press the PTT switch to
save the new setting and exit to normal operation.
When you are operating on Packet, switch the Receive Battery Saver OFF, as
the sleep cycle may “collide” with the beginning of an incoming Packet
transmission, causing your TNC not to receive the full data burst.
TX BATTERY SAVER
The FT-270R also includes a useful Transmit Battery Saver, which will automatically lower
the power output level when the last signal received was very strong. For example, when
you are in the immediate vicinity of a repeater station, there generally is no reason to use
the High Power output in order to achieve full-quieting access to the repeater. With the
Transmit Battery Saver, the automatic selection of Low Power operation conserves battery
drain significantly.
To activate the Transmit Battery Saver:
1. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 49: TXSAVETXSAVE

TRANSMITTER TIME-OUT TIMER (TOT)
The TOT feature provides a safety switch which limits transmission time to a pre-pro-
grammed value. This will promote battery conservation by not allowing you to make ex-
cessively-long transmissions, and in the event of a stuck PTT switch (perhaps if the radio
or a Speaker/Mic is wedged between car seats) it can prevent interference to other users as
well as battery depletion. As configured at the factory the TOT feature is set to “6 min-
utes,” and here is the procedure for activating it:
1. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 47: TOTTOT
TOTTOT
TOT.
3. Press the [F/L] key momentarily to enable adjustment of this Set
Mode Item.
4. Rotate the DIAL knob to set the Time-Out Timer to the desired
“Maximum TX” time (between 1 and 30 minutes), or OFF.
5. When you have made your selection, press the PTT switch to
save the new setting and exit to normal operation.
1) When your transmission time is within 10 seconds of the Time-Out Timer
expiration, an Alert bell will provide an audible warning from the speaker.
2) Since brief transmissions are the mark of a good operator, try setting up
your radio’s TOT feature for a maximum transmission time of one minute. This will
significantly improve battery life, too!
BUSY CHANNEL LOCK-OUT (BCLO)
The BCLO feature prevents the radio’s transmitter from being activated if a signal strong
enough to break through the “noise” squelch is present. On a frequency where stations
using different CTCSS or DCS codes may be active, BCLO prevents you from disrupting
their communications accidentally (because your radio may be muted by its own Tone
Decoder). The default setting for the BCLO is OFF, and here is how to change that setting:
1. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 5: BCLOBCLO
BCLOBCLO
BCLO.
3. Press the [F/L] key momentarily to enable adjustment of this Set
Mode Item.
4. Rotate the DIAL knob to set this Set Mode Item to “BCL. ONBCL. ON

(thus activating the BCLO feature).
5. When you have made your selection, press the PTT switch to

DCS CODE INVERSION
The DCS system was first introduced in the commercial LMR (Land Mobile Radio) service,
where it is now in widespread use. DCS is sometime referred to by its different proprietary
names, such as DPL® (Digital Private Line®, a registered trademark of Motorola, Inc.).
DCS uses a codeword consisting of a 23-bit frame, transmitted (subaudible) at a data rate of
134.4 bps (bit/sec). Occasionally, signal inversion can result in the complement of a code to
be sent or received. This prevents the receiver’s squelch from opening with DCS enabled,
as the decoded bit sequence would not match that selected for operation.
Typical situations that might cause inversion to occur are:
Connection of an external receiver preamplifier.
Operating through a repeater.
Connection of an external linear amplifier.
Note that code inversion does not mean that any of the above listed equipment is defec-
tive!
In certain amplifier configurations, the output signal (phase) is inverted from the input.
Small signal or power amplifiers having an odd number (1, 3, 5, etc.) of amplification stages
may result in inversion of a transmitted or received DCS code.
While under most circumstances this should not occur (amplifier designs and industry
standards take this into account), if you find that your receiver squelch does not open
when both you and the other station are using a common DCS code, you or the other
station (but not both) can try the following:
1. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 14: DCS.NDCS.N

FT-270R OPERATING MANUAL64
CHANGING THE TX DEVIATION LEVEL
In many areas of the world, channel congestion has required that operating channels be
closely spaced. In such operating environments, it often is required that operators use
reduced deviation levels, so as to reduce the potential for interference to users on adjacent
channels. The FT-270R includes a simple method of accomplishing this:
1. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 51: WID.NARWID.NAR
WID.NARWID.NAR
WID.NAR.
3. Press the [F/L] key momentarily to enable adjustment of this Set
Mode Item.
4. Rotate the DIAL knob to set this Set Mode Item to “NARROWNARROW
NARROWNARROW
NARROW.”
In this configuration (HALF DEVIATION active), the
transmitter’s deviation will be approximately ±2.5 kHz, and the
received audio output level will be increased, for easier listening
on the narrow signal.
5. When you have made your selection, press the PTT switch to save the new setting
and exit to normal operation.
The “normal” setting for the deviation (when this Menu Item is set to WIDE) is ±5 kHz.

FT-270R OPERATING MANUAL 65
In the event of erratic operation of the transceiver, it is possible that data on the micropro-
cessor may have become corrupted. While this is a highly unusual situation, the only path
to recovery may involve resetting of the microprocessor. Here’s how to do this:
1. Turn the radio off.
2. Press and hold in the MONI switch (just below the PTT switch) while turning the
radio on.
3. Rotate the DIAL knob to select one of the choices from the reset menu:
F1 SETRSTF1 SETRST

FT-270R OPERATING MANUAL66
The FT-270R includes a convenient “Clone” feature, which allows the memory and con-
figuration data from one transceiver to be transferred to another FT-270R. This can be
particularly useful when configuring a number of transceivers for a public service opera-
tion. Here is the procedure for Cloning one radio’s data to another:
1. Turn both radios off.
2. Connect the user-constructed cloning cable and two optional CT-91 Microphone
Adapters (one on each end) between the MIC/SP jacks of the two radios.
3. Press and hold in the MONI switch (just below the PTT switch) while turning the
radios on. Do this for both radios (the order of switch-on does not matter).
4. Rotate the DIAL knob on each radio to select to “F6 CLONEF6 CLONE
F6 CLONEF6 CLONE
F6 CLONE,”
then press the [F/L] key momentarily.
5. The display will disappear for a moment, then the “CLONECLONE
CLONECLONE
CLONE”
notation will appear on the displays of both radios when the Clone
mode is successfully activated in this step.
6. On the Destination radio, press the MONI switch (“- - RX - -- - RX - -
- - RX - -- - RX - -
- - RX - -”
will appear on the LCD).
7. Press and hold in the PTT switch on the Source radio; “- - TX - -- - TX - -
- - TX - -- - TX - -
- - TX - -”
will appear on the Source radio, and the data from this radio will
be transferred to the other radio.
8. If there is a problem during the cloning process, “ERRORERROR
ERRORERROR
ERROR” will
be displayed. Check your cable connections and battery voltage,
and try again.
9. If the data transfer is successful, “CLONECLONE
CLONECLONE
CLONE” will reappear on both
displays. Turn both radios off and disconnect the cloning cable.
You can then turn the radios back on, and begin normal opera-
tion.
