3. EXT DC Jack
When an external 12-Volt DC power source is available, you may connect the (optional)
E-DC-5B DC Cable w/Noise Filter or E-DC-6 DC Cable here.
Do not connect any wire to this jack if that wire is connected directly to a 28-Volt DC
source. Connecting the VXA-710 directly to a source which exceeds 15.0 Volts DC will
result in damage to the unit.
Before You Begin
Precautions
This apparatus is capable of two-way communication on channels used for critical
aviation safety communications. Therefore, it is important that this radio be kept away
from children or other unauthorized users at all times.
When making DC connections via the (optional) E-DC-5B DC cable, be absolutely
certain to observe the proper voltage level and polarity guidelines. Do not connect this
radio directly to any 24 ~ 28 Volt DC source, nor to AC power of any kind. Connecting
the VXA-710 directly to a source which exceeds 15.0 Volts DC will result in damage to
the unit.
Do not dispose of the LI-ion Battery Pack in a fire. Do not carry a LI-ion Battery Pack in
your pocket, where keys or coins could short the terminals. This could create a serious
fire/burn danger, and possibly cause damage to the LI-ion pack.
How to Install the Quick Draw Belt Clip
Connect the hanger to the rear of the VXA-710, 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 VXA-710!
Clip the Quick-Draw Belt Clip onto your belt (Figure 2).
To install the VXA-710 into the Quick-Draw Belt Clip, align the hanger with the Quick-
Draw Belt Clip, and slide the VXA-710 into its slot until a click is heard (Figure 3).
To remove the VXA-710 from the Quick-Draw Belt Clip, rotate the VXA-710 180 degrees,
then slide the VXA-710 out from the Quick-Draw Belt Clip (Figure 4).
Installation of FNB-80LI Battery Pack
The FNB-80LI is a high-performance Lithium-Ion battery providing high capacity in a very
compact package. Under normal use, the FNB-80LI may be used for approximately 300
FCC ID: K6610623X20
IC ID: 511B-10623X20
Operating Manual
Vertex Standard Co., Ltd.
7
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.
Install the FNB-80LI as shown in the illustration.
Close the Battery Pack Latch on the bottom of the radio.
Do not attempt to open any of the rechargeable LI-ion packs, as personal injury or damage
to the LI-ion pack could occur if a cell or cells become accidentally short-circuited.
Battery Charging
If the battery has never been used, or its charge is depleted, it may be charged by
connecting the NC-72B/C 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 Cable (w/cigarette
lighter plug) or E-DC-6 DC Cable may also be used for charging the battery, as shown in the
illustration. The “Now Charging . . .” will blink in the display while the battery is being
charged. When charging is finished (approximately five hours), the display will change to
indicate “Complete” and the BUSY/TX indicator will blink blue.
Important Notes:
Do not leave the charger connected to the transceiver for continuous periods in excess
of 24 hours. Long term overcharging can degrade the LI-ion battery pack and
significantly shorten its useful life.
If using a charger other than the NC-72B/C, or if using a battery pack other than the
FNB-80LI, follow the appropriate instructions provided with the charger/battery. Contact
your Dealer if you have any doubts about the appropriateness of the particular charger
or battery pack you intend to use.
Installation of FBA-23 Alkaline Battery Case (Option)
The optional FBA-23 Battery Case allows receive monitoring using two “AA” size Alkaline
batteries.
To Install Alkaline Batteries into the FBA-23
Slide the batteries into the FBA-23 as shown in the illustration, with the Negative (–) side
of the batteries touching the spring connections inside the FBA-23.
Open the Battery Pack Latch on the bottom of the radio.
Install the FBA-23 into the battery compartment on the back of the transceiver, then
close the Battery Pack Latch on the bottom of the radio.
The FBA-23 does not provide connections for charging, since Alkaline cells cannot be re-
charged. Therefore, the NC-72B/C, E-DC-5B, or E-DC-6 may safely be connected to the
EXT DC jack when the FBA-23 is installed.
FCC ID: K6610623X20
IC ID: 511B-10623X20
Operating Manual
Vertex Standard Co., Ltd.

Notes:
The FBA-23 is designed for use only with AA-type Alkaline cells.
If you do not use the VXA-710 for a long time, remove the Alkaline batteries from the
FBA-23, as battery leakage could cause damage to the FBA-23 and/or the transceiver.
Low Battery Indication
As your battery discharges during use, the voltage will gradually become lower. When
the “BATTERY” icon will blink on the LCD display, the battery pack must be recharged
before further use.
Avoid recharging Li-Ion batteries before the “Low Battery” indicator is observed, as this
can degrade the charge capacity of your Li-Ion battery pack. Vertex Standard
recommends that you carry an extra, fully-charged pack with you so you will not lose
communications capability due to a depleted Li-Ion battery.
This “deep cycling” practice will help to maintain longer overall battery life after many
recharging cycles.
AC Operation Using NC-72B/C (Receiving only)
The VXA-710 may be operated from your house current by use of the supplied NC-72B/C
Battery Charger. The NC-72B/C should only be used for reception, because it is not capable
of supplying sufficient current to support transmission.
To use the NC-72B/C, turn the transceiver off, then plug the miniature connector of the
Battery Charger into the EXT DC jack on the side of the radio. Now plug the Battery Charger
into the wall outlet. You may now turn on the transceiver.
Basic Operation
Preliminary Steps
Install a charged battery pack onto the transceiver, as described previously.
Screw the supplied antenna onto the Antenna jack. Never operate this transceiver
without an antenna connected.

FM BC band.
Directly entering frequencies from the keypad is the easiest method if you know the
frequency on which you wish to operate. Just enter the five digits of the frequency to
move to that frequency. However, there is a short-cut for frequencies ending in zero -
press the [SCAN(DW)MT] key after the last non-zero digit.
For example, to set 134.35 MHz:
press [1] Æ [3] Æ [4] Æ [3] Æ [5].
To set 118.000 MHz:
press [1] Æ [1] Æ [8] Æ [SCAN(DW)MT].
To set 118.275 MHz, you do not need to press the final “5” in the frequency:
press [1] Æ [1] Æ [8] Æ [2] Æ [7].
Note: When the entered frequency is outside of the current operating band, the entry is
ignored (i.e. VXA-710 does not permit entry of a FM BC band frequency while operating
in the AIR band).
You may also turn the top panel’s DIAL selector knob to choose the desired operating
frequency. The channel frequency will appear on the LCD.
To change frequency in 1 MHz steps, press the [F] key momentarily, then rotate the
DIAL selector knob to select the MHz digit desired. Press the [F] key once more to
resume normal channel step.
Rotate the VOL knob to set the volume level. If no signal is present, press and hold in
the MONITOR button for 2 seconds; background noise will now be heard, and you may
use this noise to set the VOL knob for the desired audio level. Press the MONITOR
button momentarily to silence the noise and resume normal (quiet) monitoring.
To turn the radio off, press and hold in the PWR switch for 3 seconds.

Note 1: In the event of extreme weather disturbances, such as storms and hurricanes, the
NOAA (National Oceanic and Atmospheric Administration) sends a weather alert
accompanied by a 1050 Hz tone and subsequent weather report on one of the NOAA
weather channels. You may setup the Alert function when receiving the Weather Alert signal
via Menu Item (6. Misc Setup, 3. WX Alert), if desired.
Note 2: The Weather Channel mode memorizes the last Weather Channel you have used,
and will retain this information until the radio is turned off.
Receive Battery Saver Setup
An important feature of the VXA-710 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 VXA-710 will remain in the “active” mode, then resume its “sleep”

Scanning Operation
Basic Scan
The VXA-710 allows you to scan automatically in the VFO*1, Main Memory, “Book” Memory,
Weather Channel*2, or BRS channel modes. It pauses on signals encountered, so you can
talk to the station(s) on that frequency, if you like.
*1: In the VFO mode, the automatic scanner is only available in the current operating band
(AIR band or FM BC band). Furthermore, on the AIR band, the automatic scanner is only
available in the COM band (118.000 - 136.975 MHz); when the scanner reaches the
uppermost frequency in the COM band, it will revert to the bottom end of the COM band and
repeat the scanning process until you cancel the scanning process.
*2: USA version only.
If you wish to scan in the NAV band (108.000 - 117.975 MHz), you can do so manually, as
described below.
Scanning operation is basically the same in each of the above modes.
Press the [SCAN(DW)MT] key momentarily to start the automatic scanner upward
(toward a higher frequency or a higher channel number).
When the scanner encounters a signal, scanning pauses and the radio remains on that

17
channel until one second after the signal disappears, after which scanning will resume.
While the scanner remains paused on a frequency, the decimal point of the frequency
display blinks. The display will be illuminated unless the Scan Lamp Feature is turned
off.
To change the scan direction, turn the DIAL selector knob one click in the opposite
direction.
To stop the automatic scanner, press the PTT switch or the [SCAN(DW)MT] key
momentarily.
The VXA-710’s automatic scanner is not operational in the NAV band (108.000 - 117.975
MHz), because the NAV stations (ILS, etc.) transmit constantly (thereby causing the scanner
to stop repeatedly). However, you can scan manually in the NAV band, per the following
procedure:
Press and hold the [SCAN(DW)MT] key to start the manual scanner. Scanning will
continue as long as the key is depressed.
Release the [SCAN(DW)MT] key to stop the manual scanner immediately.
Note: When scanning upward in frequency, when the frequency reaches the COM Band
(118.000 - 136.975 MHz) via manual scanning, the VXA-710 will switch to the automatic
scanner mode.
Channel-Skip Scanning
Continuous-carrier stations like ATIS (Automatic Terminal Information Service) or Weather
Broadcast stations inhibit scanner operation. Since these stations are always active, the
scanner will be halted repeatedly on their channels. Such channels can be set to be
“skipped” during Memory scanning (MR, Book, WX, or BRS modes), if you like, so as not to
interfere with automatic channel scanning:
Recall the Memory Channel to be skipped during scanning.
Press and hold the [9(SKIP)] key for 2 seconds. The “ icon will appear at the left of the
frequency display, indicating that the channel is to be ignored during scanning.
Later, to re-enable the memory channel for scanning, repeat the first two steps. The “
icon will disappear by the channel you have just re-enabled.
Note: A memory set to be “skipped” is still accessible for manual memory selection using
the DIAL selector knob.
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 with to set up a limit of COM band (118.000 MHz to 136.975 MHz.

Here’s how to do this:
Set the radio to the VFO mode by pressing the [SEL(SET)] key and set the radio to the
AIR band by pressing the [BAND(MODE)] key, if necessary.
Using the techniques learned earlier, store 118.000 MHz into Memory Channel “Lch”
(the “Lch” designates the Lower sub-band limit).
Likewise, store 136.975 MHz into Memory Channel “Uch” (the “Uch” designates the
Upper sub-band limit).
Switch to the Memory mode by pressing the [SEL(SET)] key once, then rotate the DIAL
to select Memory Channel “Lch.”
Press and hold in the [SCAN(DW)MT] key for 2 seconds to start PMS operation; the
“MR” label will be replaced by “PMS” in the upper left-hand corner of the display.
Tuning and scanning (pressing the [SCAN(DW)MT] key) will now be limited within the
just-programmed range.
Note: The PMS feature does not activated on the WX and BRS frequencies.
Dual Watch Operation
The Dual Watch feature automatically checks for activity on a “Priority” channel* while you
are operating on another channel. During Dual Watch operation, the current channel and the
Priority channel will each be polled for a 500 ms interval, as the VXA-710 looks for activity
on each channel.
To start Dual Watch, press the [F] key followed by [SCAN(DW)MT] key.
The “DW” icon will appear on the display.
While receiving on the “current” channel (not the Priority channel), you may push the
PTT switch at any time to transmit on that channel.
When a signal is received on the Priority channel, operation immediately shifts to the
Priority channel; the “DW” icon will blink, and the display will become illuminated.
While receiving on the priority channel, if you momentarily press the PTT switch, Dual
Watch will be disabled. You may then transmit on the Priority Channel.
To stop Dual Watch, press the [F] key followed by [SCAN(DW)MT] key.
If you wish, you may use both the Dual Watch and Scan features simultaneously. To do
this, start the Dual Watch first, then start the Scanner.
* The “Priority” channel is defined as the last-used Memory Channel (when using the VFO,
“Book” memory, and BRS channel modes) or Memory Channel “1” (when using the Main
Memory mode).
Priority Dual Watch Operation
Similar to Dual Watch operation (described on previous page), Priority Dual Watch is an

enhanced version which includes the following additional features:
The receiving time interval (ratio) between the current channel and the Priority channel
may be customized via the Menu Item “PRI Time.” See page ?? for details.
Irrespective of which channel is currently being received, when the PTT button is
pushed transmission will always occur on the Priority channel.
Before initiating Priority Dual Watch, Menu Item “DW/PRI” must be set to the “PRI” mode
(instead of “DW”). See page ?? for details.
To start Priority Dual Watch, press the [F] key followed by [SCAN(DW)MT]. The “DW”
icon will appear on the display.
While receiving on the “current” (non-Priority) channel, pressing the PTT button once
causes the radio to switch to the Priority channel and cancels Dual Watch. Press the
PTT button again to transmit on the Priority channel.
When a signal is received on the Priority channel, reception immediately shifts to the
Priority channel; the “DW” icon will blink, and the display will become illuminated unless
the Scan Lamp Feature is turned off.
While receiving on the Priority channel, if you momentarily press the PTT switch, Priority
Dual Watch will be disabled. You may then transmit on the Priority Channel.
To stop Priority Dual Watch, press the [F] key followed by [SCAN(DW)MT].
Spectrum Scope Monitor
If you assign the Spectrum Scope Monitor feature to the [USER(KEY)] key (see page ??),
you may view operating activity on channels above and below the current operating channel
while operating in the VFO, Memory Tune, and PMS modes.
The display indicates the relative signal strength on channels immediately adjacent to the
current operating frequency.
Set the radio to the VFO mode by pressing the [SEL(SET)] key, if necessary.
Press (or press and hold in) the [USER(KEY)] key to activate the Spectrum Scope
Monitor.
Once the Spectrum Scope Monitor is activated, press the [SEL(SET)] key to change the
visible bandwidth between ±15 channel and ±30 channel (default: ±30 channels). The
visible bandwidth, however, depends on the selected channel step size, so match the
channel step to those typically used in your area.
To turn the Spectrum Scope Monitor off and operate on the centered (and displayed)
channel, simply press PTT switch.
Note: Audio output will be interrupted during Spectrum Analyzer operation. This is normal.

VOR Navigation (Air Band)
To Select the VOR Mode
When entering the NAV band (108.000 - 117.975 MHz), the VXA-710 selects the VOR
mode automatically. The “Course Indicator” will appear on the display, and the “TO” or
“FROM” indicator will appear at the right of the “Course Indicator” on the display.
Note: The “Course Indicator” indicates “---°” when either your aircraft is too far away
from the VOR station or if the frequency is not correctly set to that of the VOR station.
Conversely, the “Course Indicator” will indicate “Loc” when a localizer signal is being
received.
The “TO” or “FROM” flag indicators indicate whether the VOR navigation information is
based on a course leading to the VOR station or leading away from the VOR station.
To change the flag from “TO” to “FROM” or vice versa, press the [F] key followed by
[3(FRM)DT] key or press the [F] key followed by [2(TO)CD] keys, respectively.
The (small) frequency indication may be toggled to display using larger characters (but
“Course Indicator” and “TO”/“FROM” flag are reduced in size), if you assign the “XFER”
feature to the [USER(KEY)] key. See page ?? for details.
Flying to a VOR Station
The VXA-710 can indicate the deviation from the direct course to a VOR station.
Select a VOR station on your aeronautical chart and turn the DIAL selector knob (or
enter the frequency directly with the keypad) to the frequency of the VOR station.
To indicate the deviation between your current flight path and the desired course, press
the [F] key followed by [4(CDI)] key to change to the CDI (Course Deviation Indicator)
mode. The “Course Deviation Arrow” will appear on the display when your aircraft is off
the direct course to the VOR station.
When your aircraft is off course to the right, the Course Deviation Arrow display will
show bars to the left side of the diamond (“|||”). When your aircraft is off course to
the left, the Course Deviation Arrow display will show bars to the right side of the
diamond (“|||”). Correct your course until no bars appear on either side of the CDI
“diamond” (only (“”) will be visible when the heading is correct).
To return to the DVOR mode, press the [F] key followed by [1(VOR)TN] key.
Entering a Desired Course
The VXA-710 can also be configured to indicate the deviation from the desired course, not

Note 1: The (“|||”) or (“|||”) indication will appear on the display when your
aircraft is off the desired course.
Note 2: When your heading is correct, the ABCS function (see below) may be more
useful than the course input option.
The Course Deviation Arrow points to the right when your aircraft is off course to the left,
and it points to the left when your aircraft is off course to the right.
Note 1: To get back on course, fly right more than the number of degrees indicated by
the Course Deviation Arrow.
Note 2: If the overflow indicator “υ” appears on the right side, select a heading plus 10
degrees to the desired course; if the overflow indicator “τ” appears on the left side,
select a heading minus 10 degrees.
Auto Bearing Center System (ABCS) Mode
In the CDI mode, the Auto Bearing Center System (ABCS) adds or subtracts the number of
degrees indicated by the CDI from the Omni Bearing Selector (OBS).
Position Cross-checking
Select two VOR stations on your aeronautical chart.
Set the frequency of one of the VOR stations in the VOR mode. The course indicator will
show the course deviation from the VOR radial. Note the radial you currently are on.
Now set the frequency of the other VOR station in the VOR mode. Note the radial from
the station you are on.
Extend the radials from each VOR station on the chart. Your aircraft is located at the
point where the lines intersect.
Split Operation
The split operation feature allows you to transmit a call to a Flight Service Station using the
COM band frequencies, while receiving a VOR station (in the NAV band). VOR stations
equipped with this capability typically are shown, on navigation charts, with the voice calling
frequency in parenthesis above the navigation frequency.

CTCSS Operation
The CTCSS operation allows to silently monitor for calls on busy channels and to transmit
CTCSS tone. The decode function monitors receiver audio through a narrow filter at the
same subaudible frequency, keeping the squelch closed until a matching tone is received,
while the transmit (encode) function superimpose a subaudible tone (at a frequency too low
to be heard) on the transmit carrier.
The 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(VOR)TN] and [2(TO)CD] keys, or Menu
Items (SQL Type) and (TONE Set).
Press and hold the [1(VOR)TN] key for 3 seconds. This instantly recalls Menu Item
(SQL Type).
Press the [SEL(SET)] key again to enable adjustment of this Menu Item.
Rotate the DIAL selector knob so that “T” appears at the bottom right corner on the
display; this activates the CTCSS Encoder, which allows transmit a CTCSS tone only.
Note: You may notice an additional “DCS” icon appearing while you rotate the DIAL
selector knob in this step. We’ll discuss the Digital Code Squelch system shortly.
Rotating the DIAL selector knob in above step will occasionally cause “TSQ” to appear.
When “TSQ” appears, this means that the Tone SQuelch system is active, which mutes
your VXA-710’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.
When you have made your selection of the CTCSS tone mode, press the [SEL(SET)]
key momentarily, then rotate the DIAL selector knob one click clockwise to select Menu
Item (TONE Set). This Menu selection allows setting of the CTCSS tone frequency to be
used.
Press the [SEL(SET)] key to enable the adjustment of the CTCSS frequency.
Rotate the DIAL selector knob until the display indicates the Tone Frequency you need
to be using.
When you have made your selection, press the [SEL(SET)] key to save the new setting,
then press the PTT key repetitively until the radio exits to normal operation.
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 VXA-710, and operation is very similar
to that just described for CTCSS.
Note: Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and

that you select a Tone Code.
Press and hold the [1(VOR)TN] key for 2 seconds. This instantly recalls Menu Item
(SQL Type).
Press the [SEL(SET)] key again to enable adjustment of this Menu Item.
Rotate the DIAL selector knob until “DCS” appears on the display; this activates the
DCS Encoder/Decoder.
Press the [SEL(SET)] key momentarily, then rotate the DIAL selector knob two clicks
clockwise to select Menu Item (DCS Set).
Press the [SEL(SET)] key again to enable adjustment of this Menu Item.
Rotate the DIAL selector knob until the desired DCS Code (a three-digit number). Just
set up the DCS Code to be the same as that used by your group.
When you have made your selection, press the [SEL(SET)] key to save the new setting,
then press the PTT key repetitively until the radio exits to normal operation.
Note: 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!
CTCSS/DCS Bell Operation
During CTCSS Decode or DCS operation, you may set the VXA-710 up 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 Bell:
Set the transceiver up for CTCSS Decode (“Tone Squelch”) or DCS operation, as
described previously.
Press the [F] key followed by [SEL(SET)] key to activate the Menu (“SET”) mode.
Rotate the DIAL selector knob to select Menu Item “2. Sound,” then press the
[SEL(SET)] key.
Rotate the DIAL selector knob to select Sub Menu Item “2. Bell,” then press the
[SEL(SET)] key.
Press the [SEL(SET)] key again to enable adjustment of this Menu Item.
Rotate the DIAL selector knob to select “ON” (to enable the CTCSS/DCS Bell).
Press the [SEL(SET)] key to save the new setting, then press the PTT key repetitively
until the radio exits to normal operation.
When the CTCSS/DCS Bell feature is enabled, the “BELL” icon appears at the bottom
center of the display. When a station calls you whose transceiver is sending a CTCSS tone
or DCS code which matches that set into your decoder, the “BELL” icon will blinks, flashes
the BUSY/TX indicator in sequential colors, and a ringer sounds to get your attention.

Just press and hold in the (PWR) switch for 3 seconds to turn the transceiver back on after
an APO shutdown, as usual.
Transmitter Time-Out Timer (TOT)
The TOT feature provides a safety switch which limits transmission 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 aircraft’s 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:
Press [F] key followed by [SEL(SET)] key to activate the Menu (“SET”) mode.
Rotate the DIAL selector knob to select Menu Item “4. Transmit,” then press the
[SEL(SET)] key.
Rotate the DIAL selector knob to select Sub Menu Item “4. T.O.T.” then press the key.
Press the [SEL(SET)] key again to enable adjustment of this Menu Item.
Rotate the DIAL selector knob to set the Time-Out Timer to the desired “Maximum TX”
time (1 minute, 3 minutes or 5 minutes).
When you have made your selection, press the [SEL(SET)] key to save the new setting,
then press the PTT key repetitively until the radio exit to normal operation.
Note 1: When your transmitting time is within 10 seconds of the Time-Out Timer expiration,
an alert bell will provide an audible warning from the speaker.
Note 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 1 minute. This will significantly improve
battery life, too!
Programming the Key Assignments
The [USER(KEY)] key is a user-programmable key that may be set up for a pair of functions
you use particularly frequently. The default [USER(KEY)] key functions, as set up at the
factory, have been assigned to the ANL feature (press key) and to the “Large Font” feature
(press and hold key) at the factory. These may be changed by the user, if you wish to utilize
another function or functions.
To program the function assigned to a key:
Press [F] key followed by [SEL(SET)] key to activate the Menu (“SET”) mode.
Rotate the DIAL selector knob to select Menu Item “5. Key Set,” then press the
[SEL(SET)] key.

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:
