Precautions
Belt Clip Installation
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/E-DC-6 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-300 directly to a source which exceeds 15.0
Volts DC will result in damage to the unit. The Limited
Warranty for this product does not cover damage caused
by the application of improper voltage.
Do not dispose of the Ni-MH Battery Pack in a fire.
Do not carry a Ni-MH 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 Ni-MH pack.
Although the VXA-300 is designed to be Submersible (3 ft., 30 min.), its enclosure is not designed to
guarantee protection from ingress of water under extreme pressure. Do not allow the radio to become submerged in deep water, and do not subject it to water
spray under pressure.
Connect the hanger to the rear of the VXA-300, 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-300.
Clip the Quick-Draw Belt Clip onto your belt (Figure
2).
To install the VXA-300 into the Quick-Draw Belt Clip,
align the hanger with the Quick-Draw Belt Clip, and
slide the VXA-300 into its slot until a click is heard
(Figure 3).
To remove the VXA-300 from the Quick-Draw Belt
Clip, rotate the VXA-300 180 degrees, then slide the

If the transceiver and battery pack are inserted correctly, the RED indicator on the CD-28 will glow. A
fully-discharged pack will be charged completely in
12 hours.
10
Important Notes:
The NC-88 is not designed to power the transceiver
for operation (reception or transmission).
Do not leave the charger 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.
If using a charger other than the NC-88/CD-28, or if
using a battery pack other than the FNB-83, 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.

Tuning Methods
Throughout this manual, you will see references to several different frequency setting methods. Each will be particularly useful in a particular operating situation, and they
are described below:
VFO (Variable Frequency Oscillator)
The VFO is a “tuning dial”
system which allows you to
tune through the NAV or COM
bands using the DIAL selector,
the Keypad, or the scanner. The VXA-300 has two
VFOs which are called VFO-A and VFO-B. Press the
[SCAN(DW)] key momentarily to switch between
VFO-A and VFO-B. You may set VFO-A to the NAV
band, and VFO-B to the COM band, if you like.
MR (Memory Recall)
The MR (Memory Recall)
mode of the VXA-300 provides the user with the ability
to store and recall as many as
150 channels in the radio’s main memory bank. These
memory channels may also be labeled by you with an
alpha/numeric name of up to 8 characters in length, to
aid in quick identification of the channel. See page 28
for details on creating alpha/numeric labels.
VXA-300 PILOT III OPERATING MANUAL
BOOK (Pre-Programmed) Memories
The Book memories are preprogrammed, either at the factory or by your Dealer (depending on your country’s requirements), typically including the major COM and
NAV band station frequencies used in your area. The
Book memories can be changed by the user. See page

ADVANCED OPERATION
Receive Battery Saver Setup
An important feature of the VXA-300 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-300 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 Menu System:

SCANNING OPERATION
The VXA-300 allows you to scan automatically in the
VFO 1, Main Memory, “Book” Memory, or Weather
Channel2 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 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 at the right.
Scanning operation is basically the same in each of the
above modes.
Press and hold in the
[SCAN (DW)] key for 2
seconds 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 channel until one sec-
30
ond 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 VOLUME
knob momentarily. You may also just press the [SCAN
(DW)] key.
The VXA-300’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)] key to start the
manual scanner. Scanning will continue as long as the
key is depressed.
Release the [SCAN (DW)] key to stop the manual
scanner immediately.
VXA-300 PILOT III OPERATING MANUAL
SCANNING OPERATION
Note: When scanning upward in frequency, when the frequency reaches the COM Band (118.000 ~ 136.975 MHz)
via manual scanning, the VXA-300 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 or WX modes), if you like,
so as not to interfere with automatic channel scanning:
Recall the Memory Channel to be skipped during scanning.
Press the [F] key momentarily, then press the

Note: A memory set to be “skipped” is still accessible for
manual memory selection using the DIAL selector knob.
31
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-300 looks for activity on each
channel.
To start Dual Watch,
press the [F] key momentarily, then press the
[SCAN (DW)].
The “
” 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
“
” 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 [F] [SCAN (DW)].
32
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 mode) or Memory
Channel 1 (when using the Main Memory or Book Memory
modes).

VOR NAVIGATION
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.
Programming a Transmit Frequency
Press the VOLUME knob, repeatedly if necessary, to
select the VFO mode.
Set a NAV band (108.000 - 117.975 MHz) frequency
using the DIAL selector knob or keypad.
Press the [F] key momentarily, then press the [MW
(SPL-W)] key. The “
” icon will blink, and the
transmit frequency will appear on the display.
Now set your radio’s transmit frequency, where the
Flight Service Station will be listening for calls, using
the DIAL selector knob or keypad.
Press and hold in the [MW (SPL-W)] key for 2 seconds to save the transmit frequency and return to the
NAV band frequency.
Operating in the Split Mode
It is assumed that you have already set the desired
VOR station’s frequencies (in the NAV band) per the
above instructions.
Press the [F] key momentarily,
then press the [7 (SPL)] key
to turn on the “Split” function.
The “
” icon will appear
on the display.
Press and hold in the PTT switch to transmit on the
split transmit frequency.
Release the PTT switch to return to the receive mode.
To disable the “Split” function, press [F] [7 (SPL)]
again.
Note: A split frequency can be programmed into each
memory channel independently. Set a transmit frequency
before programming the memory channel, if desired. The
split function on/off setting can also be programmed into
a memory channel.
Note: You have now stored the separate transmit frequency,
but you have not yet activated the split-frequency function; go on to the next section.
