VX-120/170 OPERATING MANUAL
General Description
The VX-120/170 is a small size FM hand-held providing up to five watts of RF power and
wealth of convenient features for 2m amateur band.
New and exciting features of the VX-120/170 are the Emergency Automatic ID (EAI) function,
that will automatically cause your VX-120/170 to transmit your callsign and engage your rig’s
microphone, even if you are disabled and unable to press the PTT switch; 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 Vertex Standard’s WIRES™
(Wide-coverage Internet Repeater Enhancement System), a transmit Time-Out Timer (TOT),
Automatic Power-Off (APO), Automatic Repeater Shift (ARS), Vertex Standard’s exclusive
ARTS™ (Auto-Range Transponder System) which “beeps” the user when you move out of
communications range with another ARTSTM 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.
We appreciate your purchase of the VX-120/170, and encourage you to read this manual
thoroughly, so as to learn about the many exciting features of your exciting new Vertex

Installation of Accessories
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 bands, 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 transceiver until it is snug. Do not over-tighten by use of extreme
6/64
Vertex Standard Co., Ltd.
FCC ID: K6620223X20

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 compartment 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.
Battery Charging
If the battery has never been used, or its charge is depleted, it may be charged by connecting
the NC-88 Overnight Battery Charger, as shown in the illustration, to the EXT DC jack. If only
12 ~ 16 Volt DC power is available, the optional E-DC-5B DC Adapter (with its cigarette
lighter plug) may also be used for charging the battery.
A fully-discharged pack will be charged completely in 10 hours. Disconnect the NC-88 from
the EXT DC jack and the AC line outlet.
Important Note
The NC-88 is not designed to power the transceiver for operation (reception or
transmission).
Do not leave the NC-88 connected to the transceiver for continuous periods in excess of
24 hours. Long term overcharging can degrade the Ni-MH battery pack and significantly
shorten its useful life.
7/64
Vertex Standard Co., Ltd.
FCC ID: K6620223X20
IC ID: 511B-20223X20
VX-120/170 OPERATING MANUAL
Please be advised that the NC-88 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 “BATTERY” 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 “Low Battery” indicator is observed, as this
can degrade the charge capacity of your Ni-MH battery pack.
Installation of FBA-25A Alkaline Battery Case (option)
The optional FBA-25A Battery Case allows operation of the VX-120/170 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.
Interface of Packet TNCs
The VX-120/170 may be used for Packet operation, using the optional CT-44 microphone
adapter (available from your Yaesu dealer) for easy interconnection to commonly-available
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 VOLUME knob,
as with voice operation. The input level to the VX-120/170 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 59 for details regarding Battery Saver setup.

VX-120/170 OPERATING MANUAL
Operation
R. F. says: Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many features of
the VX-120/170. I know you’re anxious to get on the air, but I encourage 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 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 and Squelch Setting
At first, set the SQL knob fully counter-clockwise. Now, you may rotate the VOL/PWR
knob to adjust the receiver level for a comfortable listing level, using the background
noise as a reference.
To set the squelch, turn the SQL knob clockwise, slightly past the point where the
background noise is muted. This is the point of best sensitivity to weak signals, and we
recommend that you not rotate the SQL knob very much past the point where the
background noise is just silenced.
R.F. Says: 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 ?? 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 VX-120/170 has, try using that mode for silent monitoring of busy channels.
Frequency Navigation
The VX-120/170 will initially be operating in the “VFO” mode, a channelized system which
9/64
Vertex Standard Co., Ltd.
FCC ID: K6620223X20
IC ID: 511B-20223X20
VX-120/170 OPERATING MANUAL
allows free tuning throughout the currently-selected operating band.
Three basic frequency navigation methods are available on the VX-120/170:
1) Tuning Dial
Rotation of the DIAL allows tuning in the pre-programmed steps established for the current
operating band. Clockwise rotation of the DIAL causes the VX-120/170 to be tuned toward a
higher frequency, while counter-clockwise rotation will lower the operating frequency.
If you press the [F/W] 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 VX-120/170.
2) Direct Keypad Frequency Entry (VX-170 only)
The desired operating frequency may be entered directly from the keypad.
To enter a frequency directly, just keying 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 [▲] or [▼] key for one second to initiate upward or downward
scanning, respectively (Manual VFO Scan).
For scanning within a limited sub-band range, from the VFO mode, press and hold in the
[MR(SKIP)] key for one second to begin scanning toward a higher frequency within the
previously-defined sub-band (Programmed VFO Scan). Details regarding sub-band setup
may be found on page ??.
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
VX-120/170 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 VX-120/170 will then hold on that frequency according to the setting of the
“RESUME” mode (Set Mode Item 32: RESUME). Press the PTT switch momentarily to
cancel the scanning. This only stops the scan; it does not cause transmission to occur. See
page // for details regarding Scan Operation.
Transmission
Once you have set up an appropriate frequency inside the 144 MHz Amateur band on which
10/64
Vertex Standard Co., Ltd.
FCC ID: K6620223X20
IC ID: 511B-20223X20
VX-120/170 OPERATING MANUAL
the VX-120/170 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 indicates “Medium Power”
operation. Additionally, the “LOW” icon will appear at the bottom of the display while
operating on the “Low Power” and “Medium Power” settings.
R.F. Says: 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/W] key, then press the [3(LOW)](VX-170) or [LOW(SET/LOCK)](VX-120)
key. The LCD shows the current power output level.
Rotate the DIAL knob to select the desired power output level. Available selections are
“HIGH” (5 W), “MID” (2 W), and “LOW” (0.5 W).
When you have made your choice, press the PTT switch to save the new setting and
return to normal operation.
R.F. Says: 1) The VX-120/170 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/W]
key, when press the PTT switch, to cause the VX-120/170 to transmit (temporarily) on High
power. After one transmission, the power level will revert to the previously-selected (“Low” or
“Medium” power) setting.
Advanced Operation
Now that you’re mastered the basics of VX-120/170 operation, let’s learn more about some of
the really neat features.

VX-120/170 OPERATING MANUAL
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
transceivers. The VX-120/170 includes a number of features which make repeater operation
simple and enjoyable.
Repeater Shifts
The VX-120/170 has been configured, at the factory, for 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 VX-120/170 provides a convenient Automatic Repeater Shift feature, which causes the
appropriate repeater shift to be applied automatically whenever you tune into the designated
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/W] key, then press the [0(SET)] key to enter the Set mode.
2.
Rotate the DIAL knob to select Set Mode Item 4: ARS.
3.
Press the [F/W] key momentarily to enable adjustment of this Item.
4.
Rotate the DIAL knob to select “ARS. ON.”
5.
When you have made your selection, press the PTT switch to save the new setting and
return to normal operation.
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/W] 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.MOD.
3.
Rotate the DIAL knob to select the desired shift among “RPT.–,” “RPT.+,” and
“RPT.OFF.”

VX-120/170 OPERATING MANUAL
4.
When you have made your selection, press the PTT switch to save the new setting and
return to normal operation.
R. F. Says: 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.
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/W] key, then press the [0(SET)] key to enter the Set mode.
2.
Rotate the DIAL knob to select Set Mode Item 41: SHIFT.
3.
Press the [F/W] key momentarily to enable adjustment of this Item.
4.
Rotate the DIAL knob to select the new repeater shift magnitude.
5.
When you have made your selection, press the PTT switch to save the new setting and
return to normal operation.
R.F. Says: 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 ??.
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 (output) frequency. While you are listening on the
input frequency to the repeater using the [REV(HOME)] key, the repeater offset icon will
blink.
R. F. Says: The configuration of this key may be set either to “RV” (for checking the input
frequency 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 75.
VFO Split Mode

VX-120/170 OPERATING MANUAL
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 procedure:
1.
Press the [VFO(PRI)] key, as needed, to select VFO-A. Set VFO-A for the receiving
2.
Now press the [VFO(PRI)] key, and set VFO-B for the desired transmit frequency (e.g.
144.750 MHz).
3.
Press the [VFO(PRI)] key once more to re-establish VFO-A as the “Main” (receive) VFO.
4.
Press the [F/W] key, then press the [0(SET)] key to enter the Set mode.
5.
Rotate the DIAL to select Set Mode Item 43: SPLIT.
6.
Press the [F/W] key, then rotate the DIAL to set this function “ON.”
7.
Press the PTT key once to save the new setting and exit to normal operation.
8.
You will now be operating in a Split mode. When you press the PTT key to transmit, you
will observe that VFO-A and VFO-B will reverse positions. The VFO selection indicator
“-b-” will blinks 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 set Set Mode
Item 43: SPLIT to “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 ??.
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 VX-120/170, and is
very easy to activate.
R.F. Says: 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.

VX-120/170 OPERATING MANUAL
1.
Press the [F/W] key, then press the [1(SQ TYP)] key to enable selection of the
CTCSS/DCS/ECS mode.
2.
Rotate the DIAL knob so that “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 “TSQL”
notation to appear. When “TSQL” is displayed, this means that the Tone SQueLch
system is active, which mutes your VX-120/170’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.
R.F. Says: 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 VX-120/170’s receiver (instead of opening the squelch) when it
receives a call from the radio sending a matched CTCSS tone. The “TSQ” 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.
5.
When you have made your selection of the CTCSS tone mode, press the PTT switch to
save the new setting.
6.
Press the [F/W] key, then press the [2(CODE)] key to enable adjustment of the CTCSS
frequency.
7.
Rotate the DIAL knob until the display indicates the Tone Frequency you need to be
using (ask the repeater owner/operator if you don’t know the tone frequency).
8.
When you have made your selection, press the [F/W] key momentarily to save the new
settings and exit to normal operation. This is different than the usual method of restoring
normal operation, and it applies only to the configuration of the CTCSS/DCS
frequencies.
R.F. Says: 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 VX-120/170 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.

VX-120/170 OPERATING MANUAL
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 VX-120/170, 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.
R.F. Says: 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/W] key, then press the [1(SQ TYP)] key to enable selection of the
CTCSS/DCS/ECS mode.
2.
Rotate the DIAL knob until the “DCS” indication appears on the display; this activates the
DCS Encoder/Decoder.
3.
Press the PTT key to save the new setting.
4.
Press the [F/W] 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/W] key momentarily to save the new
settings and exit to normal operation.
R.F. Says: 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 transmission. 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:

VX-120/170 OPERATING MANUAL
1.
Set the radio up for either CTCSS or DCS Decoder operation (see the previous
discussions). In the case of CTCSS, “T SQ” will appear on the display; in the case of
DCS, “DCS” will appear on the display.
2.
Press the [F/W] key, then press the [2(CODE)] key.
3.
Press and hold in the [ ] or [ ] key for one second 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/W] key to lock in that tone/code, then press the
[F/W] key again to exit to normal operation.
R.F. Says: 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.
EPCS (Enhanced Paging & Code Squelch)
The VX-120/170 includes an Enhanced CTCSS tone encoder/decoder and a dedicated
microprocessor providing paging and selective calling feature. 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.
Meanwhile, on the paging radio, the Enhanced Paging and Code Squelch system will be
disabled after the PTT key is released after the paging transmission. You may re-activate the
Enhanced Paging and Code Squelch system again using Set Mode Item 29: PAGER, if
desired.

CTCSS/DCS/EPCS Bell Operation
During CTCSS Decode, DCS, or EPCS operation, you may set up the VX-120/170 such that
a ringing “bell” sound alerts you to the fact that a call is coming in. Here is the procedure for
activating the CTCSS/DCS/EPCS Bell:

desired CTCSS or DCS tones, as well as any desired repeater offset. The power level
may also be set at this time, if you wish to store it.
2.
Press and hold in the [F/W] key for one second.
3.
Within ten seconds of releasing the [F/W] key, you need to make a decision 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 100 memory channels, if you’re in a hurry (101
201
301 …) by pressing the [VFO(PRI)] key (multiple times, if necessary).
4.
Press the [F/W] 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.
Turn to the desired transmit frequency, then press and hold in the [F/W] key for one
second.
3.
Within ten seconds of releasing the [F/W] 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 press the [F/W] key once more momentarily while
holding the PTT switch in (this does not key the transmitter).
R.F. Says: Whenever you recall a memory which contains independently-stored transmit and
receive frequencies, the “–+” indication will appear in the display.
Memory Recall
1.
While operating in the VFO mode, press the [MR(SKIP)] key to enter the Memory mode.
2.
Rotate the DIAL knob to select the desired channel.
3.
To return to the VFO mode, press the [VFO(PRI)] key.

HOME Channel Memory
A special one-touch “HOME” channel is available, to allow quick recall of a favorite operating
frequency.
Home Channel storage is simple to accomplish:
1.
Change the setting of Set Mode Item 33: REV/HM from “REV” to “HOME,” if it is not
already set to this option (see page ??).

weather channels. See page 39 for details regarding activation of this mode.
Scanning
The VX-120/170 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:

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 broadcasts, the scanner
will likely remain on this frequency indefinitely.
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.
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

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 #L01 (the “L” designates the Lower sub-band limit).
3.
Likewise, store 148.000 MHz into Memory Channel #U01 (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 (PMSxx),
then press the [VFO(PRI)] key.

Emergency Feature
Emergency Channel Operation
The VX-120/170 includes an “Emergency” feature which may be useful if you have someone
monitoring on the same frequency as your transceiver’s “Home” channel. See page ?? for
details on setting the Home channel.
The “Emergency” feature is activated by pressing and holding in the [4(RPT]] key for one
second. When this is done, (A) the radio is placed on the UHF amateur band Home channel,
(B) it emits a loud “Alarm” sound (the volume is controlled by the VOL knob), (C) it flashes the
LCD/keypad lamp, (D) if you press the PTT key, you will disable the Emergency feature
temporarily; you can then transmit on the Home channel, and (E) two seconds after the PTT
release, the Emergency feature will resume.
To disable the “Emergency” feature, press the [F/W] key momentarily or turn the radio off by
rotating the VOL/PWR knob fully counter-clockwise into the click-stop position.
Use this feature if you are out for a walk and want a quick way of alerting a family member as
to a dangerous situation. The alarm sound may discourage an attacker and allow you to
escape.
R.F. Says: 1) Be sure to arrange with a friend or family member to be monitoring on the same
frequency, as there will be no identification sent via the Emergency alarm sound. And do not
transmit the alarm tone except in a true emergency!
2) The “Emergency” feature may be changed to another function via Set Mode Item 21: EMG
S; see page ?? for details.
Emergency Automatic ID (EAI) Feature
The Emergency Automatic ID (EAI) feature can be used for searching for persons who are
incapacitated in disasters like earthquakes, especially search-and-rescue personnel who
may have become injured in a debris field. In such cases, if another searcher sends out a
unique command (CTCSS tone pair), the radio of the incapacitated party, who may not be
able to speak or even press the PTT, will automatically cause the injured party’s radio to
transmit, so others may perform direction-finding and effect a rescue. The callsign of the
incapacitated person will also be transmitted, to assist the rescue team.
If an emergency group is working in a dangerous area, all members should engage the EAI

feature on their transceiver, so that others can provide assistance to a fallen team member, if
necessary.
The Emergency Automatic ID (EAI) Feature has two operating modes: (1) Interval mode and
(2) Continuous mode.
In the Interval mode, when the VX-120/170 receives the CTCSS tone pair which is stored in
the Receiving Pager Code Memory (configured via Set Mode Item 31: PAG.CDR) on the
frequency which is stored in Memory Channel “000,” the radio will automatically transmit a
short (0.5 second) beep tone every 2.5 seconds until the EAI timer expiration at the power
level stored in that memory channel; it is NOT necessary for the incapacitated person to
press the PTT switch. Furthermore, if your call sign is stored in the radio by Set Mode Item
11: CW WRI, the radio will transmit your callsign on the air when this feature is first engaged
by the remote page, and every 10 minutes thereafter.
In the Continuous mode, when the VX-120/170 receives the CTCSS tone pair which is stored
in the Receiving Pager Code Memory (configured via Set Mode Item 31: PAG.CDR) on the
frequency which is stored in Memory Channel “000,” the radio will automatically transmit
continuously, until the EAI timer expiration, at the power level stored in that memory channel;
it is NOT necessary for the incapacitated person to press the PTT switch. Furthermore, if your
call sign is stored in the radio by Set Mode Item 11: CW WRI, transmit your callsign on the air
at the activating this feature, and after that every 10 minutes thereafter.
The “callsign” ID can be changed to any desired sequence of characters, such as a name.
After sending the callsign or name, the radio will repeatedly transmit three tones for a
user-defined period of time (between 1 and 30 minutes). The callsign or name will be
transmitted every 10 minutes.
The Emergency Automatic ID (EAI) feature requires that you (1) store the CTCSS Tone Pair
into the Receiving Pager Memory (see page 44 for procedure), and (2) store the desired UHF
coordination frequency into Memory Channel “000” (see page 28 for procedure).

Smart Search Operation
The Smart Search feature allows you to load frequencies automatically according to where
activity is encountered by your radio. When Smart Search is engaged, the transceiver will
search above and below your current frequency, storing active frequencies as it goes
(without stopping on them even momentarily); these frequencies are stored into a special
Smart Search memory bank, consisting of 31 memories (15 above the current frequency, 15
below the current frequency, plus the current frequency itself).
Two basic operating modes for Smart Search are available:
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.
CONT: In this mode, the transceiver will make one pass in each direction as with One-Shot
searching; if all 31 channels are not filled after the first sweep, however, the radio will
continue sweeping until they are all filled.

IC ID: 511B-20223X20
VX-120/170 OPERATING MANUAL
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 activated,
if desired.
Whenever you push the PTT, or every 25 (or 15) seconds after ARTS™ is activated, your
radio will transmit a signal which includes a (subaudible) DCS signal for about 1 second. If
the other radio is in range, the beeper will sound (if enabled) and the display will show “IN
RNG” as opposed to the out of range display “OUT RNG” in which ARTS™ operation begins.
Whether you talk or not, the polling every 15 or 25 seconds will continue until you de-activate
ARTS™. Every 10 minutes, moreover, you can have your radio transmit your callsign via CW,
so as to comply with identification requirements. When ARTS™ is de-activated, DCS will also
be deactivated (if you were not using it previously in non-ARTS™ operation).
If you move out of range for more than one minute (four pollings), your radio will sense that no
signal has been received, three beeps will sound, and the display will revert to “OUT RNG.” If
you move back into range, your radio will again beep, and the display will change back to the
“IN RNG” indication.
During ARTS™ operation, your operating frequency will continue to be displayed, but no
changes may be made to it or other settings; you must terminate ARTS™ in order to resume
normal operation. This is a safety feature designed to prevent accidental loss of contact due
to channel change, etc.
Basic ARTS™ Setup and Operation
1.
Set your radio and the other radio(s) to the same DCS code number, per the discussion
on page ??.
2.
Press and hold in the [2(CODE)] key for one second. You will observe the “OUT. RNG”
display on the LCD below the operating frequency. ARTS™ operation has now
commenced.
3.
Every 25 seconds, your radio will transmit a “polling” call to the other station. When that
station responds with its own ARTS™ polling signal, the display will change to “IN RNG”
to confirm that the other station’s polling code was received in response to yours.
4.
Press the [F/W] key momentarily to exit ARTS™ operation and resume normal
functioning of the transceiver.
R.F. Says: ARTS™ constitutes a form of “remote control” operation that may be restricted to
certain frequencies. U.S. users should confirm the current status of §97.201(b) of the FCC’s

ARTS™ Alert Beep Options
The ARTS™ feature allows two kinds of alert beeps (with the additional option of turning them
off), so as to alert you to the current status of ARTS™ operation. Depending on your location
and the potential annoyance associated with frequent beeps, you may choose the Beep
mode which best suits your needs. The choices are:
INRANG: The beeps are issued only when the radio first confirms that you are within range,
but does not re-confirm with beeps thereafter.
ALWAYS: Every time a polling transmission is received from the other station, the alert beeps
will be heard.

5/10/12.5/15/20/25/50/100 kHz per step, as well as an automatic step selection based on the
current operating frequency (“AUTO”), any number of which may be important to your
operating requirements. The VX-120/170 is set up at the factory in the “AUTO” configuration,
which probably is satisfactory for most operation. However, if you need to change the

channel step increments, the procedure to do so is very easy.
1.
Press the [F/W] key, then press the [0(SET)] key to enter the Set mode.
2.
Rotate the DIAL knob to select Set Mode Item 45: STEP.
3.
Press the [F/W] key momentarily to enable adjustment of this Item.
4.
Rotate the DIAL knob to select the new channel step size.
5.
When you have made your selection, press the PTT switch to save the new setting and
return to normal operation.
Receive Battery Saver Setup
An important feature of the VX-120/170 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 VX-120/170 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/W] key, then press the [0(SET)] key to enter the Set mode.
2.
Rotate the DIAL knob to select Set Mode Item 37: RXSAVE.
3.
Press the [F/W] key momentarily to enable adjustment of this Set Mode Item.
4.
Rotate the DIAL knob to select the desired “sleep” duration. The selections available are
200 ms, 300 ms, 500 ms, 1 second, 2 seconds, or OFF. The default value is 200 ms.
5.
When you have made your selection, press the PTT switch to save the new setting and
exit to normal operation.
R.F. Says: 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 VX-120/170 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/W] key, then press the [0(SET)] key to enter the Set mode.
2.
Rotate the DIAL knob to select Set Mode Item 49: TXSAVE.

Transmit Battery Saver).
5.
When you have made your selection, press the PTT switch to save the new setting and
exit to normal operation.
Disabling the TX/BUSY Indicator
Further battery conservation may be accomplished by disabling the TX indicator while
transmitting and disabling the BUSY indicator while receiving a signal. Use the following
procedure:
1.
Press the [F/W] key, then press the [0(SET)] key to enter the Set mode.
2.
Rotate the DIAL knob to select Set Mode Item 8: BSY.LED if you wish to disable the
BUSY indicator or Set Mode Item 48: TX.LED if you wish to disable the TX indicator.
3.
Press the [F/W] key momentarily to enable adjustment of this Set Mode Item.
4.
Rotate the DIAL knob to set this Set Mode Item to “LED.OFF” (thus disabling the BUSY
or TX lamp).
5.
When you have made your selection, press the PTT switch to save the new setting and
exit to normal operation.
6.
If you wish to re-enable the TX/BUSY Indicator, just repeat the above procedure, rotating
the DIAL knob to select “LED. ON” in step 4 above.
Automatic Power-Off (APO) Feature
The APO feature helps conserve battery life by automatically turning the radio off after a
user-defined period of time within which there has been no dial or key activity. The available
selections for the time before power-off are 0.5 to 12.0 hours in 0.5 hour multiple, as well as
APO Off. The default condition for the APO is OFF, and here is the procedure for activating it:
1.
Press the [F/W] key, then press the [0(SET)] key to enter the Set mode.
2.
Rotate the DIAL knob to select Set Mode Item 1: APO.
3.
Press the [F/W] key momentarily to enable adjustment of this Set Mode Item.
4.
Rotate the DIAL knob to select the desired time period after which the radio will
automatically shut down.
5.
When you have made your selection, press the PTT switch to save the new setting and
exit to normal operation.
When the APO is activated, the “TIMER” icon will appear at the upper right corner on the LCD.

down the radio automatically.
Rotate the VOL/PWR knob counter-clockwise to the “off” position, then clockwise out of the
click-stop, to turn the radio on after an APO shutdown.
Transmitter Time-Out Timer (TOT)
The TOT feature provides a safety switch which limits transmission time to a
pre-programmed value. This will promote battery conservation by not allowing you to make
excessively-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 OFF, and here
is the procedure for activating it:
1.
Press the [F/W] key, then press the [0(SET)] key to enter the Set mode.
2.
Rotate the DIAL knob to select Set Mode Item 47: TOT.
3.
Press the [F/W] 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.
R.F. Says: 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/W] key, then press the [0(SET)] key to enter the Set mode.
2.
Rotate the DIAL knob to select Set Mode Item 5: BCLO.
3.
Press the [F/W] key momentarily to enable adjustment of this Set Mode Item.
4.
Rotate the DIAL knob to set this Set Mode Item to “BCL. ON” (thus activating the BCLO
feature).

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 defective!
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/W] key, then press the [0(SET)] key to enter the Set mode.
2.
Rotate the DIAL knob to select Set Mode Item 14: DCS.N/R.
3.
Press the [F/W] key momentarily, then rotate the DIAL knob to select one of the following
modes:
T/RX N: Encoder, Normal; Decoder, Normal
RX R: Encoder, Normal; Decoder, Reverse (Inverted)
TX R: Encoder, Reverse (Inverted); Decoder, Normal
T/RX R: Encoder, Reverse (Inverted); Decoder, Reverse (Inverted)
4.
When you have made your selection, press the PTT switch to save the new setting and
exit to normal operation.
5.
Remember to restore the default setting to “T/RX N” (Encoder; Normal, Decoder;
Normal) when done.

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 VX-120/170 includes a simple method of accomplishing this:
1.
Press the [F/W] key, then press the [0(SET)] key to enter the Set mode.
2.
Rotate the DIAL knob to select Set Mode Item 51: WID.NAR.
3.
Press the [F/W] key momentarily to enable adjustment of this Set Mode Item.
4.
Rotate the DIAL knob to set this Set Mode Item to “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.
R.F. Says: The “normal” setting for the deviation (when this Menu Item is set to WIDE) is ±5
kHz.
Reset Procedures
In the event of erratic operation of the transceiver, it is possible that data on the
microprocessor 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 choice from the reset menu:
F1 SETRST: Resets the Set (Menu) mode settings to their factory defaults.
F2 MEMRST: Clears the Memory settings to factory defaults.
F3 MB RST: Clears the Memory Bank Assignments.
F4 ALLRST: Clears all memories and other settings to factory defaults.
4.
Press the [F/W] key momentarily to complete the reset procedure.
Cloning
The VX-120/170 includes a convenient “Clone” feature, which allows the memory and
configuration data from one transceiver to be transferred to another VX-120/170. This can be
particularly useful when configuring a number of transceivers for a public service operation.

VX-120/170 OPERATING MANUAL
Here is the procedure for Cloning one radio’s data to another:
1.
Turn both radios off.
2.
Connect the optional CT-27 Clone Cable 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 job on each radio to select to “F6 CLONE,” then press the [F/W] key
momentarily.
5.
The display will disappear for a moment, then the “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--” will appear on the LCD).
7.
Press and hold in the PTT switch on the Source radio; “--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, “ERROR” will be displayed. Check your
cable connections and battery voltage, and try again.
9.
If the data transfer is successful, “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 operation.
Set (Menu) Mode
The VX-120/170 Set Mode, already described in parts of many previous chapters, is easy to
activate and set. It may be used for configuration of a wide variety of transceiver parameters,
some of which have not been detailed previously. Use the following procedure to activate the
Set Mode:
1.
Press the [F/W] key, then press the [0(SET)] key to enter the Set mode.
2.
Rotate the DIAL knob to select the Set Mode Item to be adjusted.
3.
Press the [F/W] key momentarily to enable adjustment of the Set Mode Item.
4.
Rotate the DIAL knob to adjust or select the parameter to be changed on the Set Mode
Item selected in above step.
5.
After completing your selection and adjustment, press the PTT switch momentarily to
save the new setting and exit to normal operation.
R.F. Says: 1) Some Set Mode Items (like Set Mode Item 46: TN FRQ) require that the [F/W]
key be pressed after setting of the parameter, and before exiting to normal operation.
2) Two Set Mode Item numbers (in the factory default, Set Mode Item 34: RF SQL, and 42:
SKIP) will blink while selecting the Set Mode Item; this indicates that this Set Mode Item has
been assigned to the [7(P1)] or [8(P2)] key of the keypad.
