The Vertex Standard VXA-150 ProV is a compact, stylish, solid hand-held transceiver providing commu-
nication (transmit and receive) capability on the International Aircraft Communication Band (“COM” band:
118 ~ 136.975 MHz), and it additionally provides receive on the “NAV” band (108 ~ 117.975 MHz).
The VXA-150 includes our exclusive two-mode display with upright or inverted viewing when on your
belt, NOAA weather band monitoring, 8-character Alpha/Numeric Display, 50 Memory Channels, and 100
“Book Memory” Channels.
The following pages describe the Controls & Connectors, Accessories & Options, and Specification of the
VXA-150. With proper care and operation, the transceiver will provide many years of reliable communications.

TOP Panel
Antenna Jack
This SMA jack accepts the supplied flexible antenna,
or another antenna designed to provide 50 W impedance on the Aircraft Communication Band.
POWER/VOLUME Knob
Turn this control clockwise to turn the radio on and to
increase the volume. Counterclockwise rotation into
the click-stop will turn the radio off.
CHANNEL Selector Knob
This 20-position detended rotary switch tunes the operating frequency or selects the memory channels.
Pressing this knob downward momentarily selects the
tuning methods among the VFO (Variable Frequency
Oscillator), MR (Memory Recall), BOOK (Pre-Programmed Memories), and WX (Weather Channel
Memories) mode.
Front Panel
LCD (Liquid Crystal Display)
The display shows the selected operating conditions
as indicated on the next page.
The display may be changed to “inverted” viewing
via the Menu.
BUSY/TX Indicator Lamp
This lamp glows green when a signal is being received
and red when transmitting.
Loudspeaker
The internal speaker is located in this position.
Microphone
Speak across this opening in a normal voice level while
pressing the PTT switch.
Keypad
Several keys have dual functions.
The primary functions are labeled on the key top (activated by simply pressing the key momentarily),
while secondary functions are labeled in yellow above
the top edge of the key (activated by pressing the [F
key first, then the indicated key).

Battery Pack Latch
Open this latch for battery removal.
PTT (PUSH TO TALK) Switch
Press this button to transmit when you are operating
in the COM band. Release this button to return to the
“RECEIVE” mode.
MONITOR Switch
This button may be pressed to “open” the squelch
manually, allowing you to listen for very weak signals. Press and hold this button for 2 seconds to “open”
the squelch continuously. Press this button again to
resume normal (quiet) monitoring.
LAMP Switch
Pressing the LAMP switch momentarily will illuminate the
display and keypad for five seconds, after which the backlighting will automatically turn off. Press and hold this
switch for 2 seconds to activate the back-lighting lamp continuously. To turn the lamp off, press this switch again. The
LAMP switch may be configured in several ways via
the Menu.
MIC/EAR Jack
You may connect the supplied CT-60 Headset Cable
or the (optional) MH-44A4B Speaker/Microphone to
this jack.
Never connect any Speaker/Microphone that is
not recommended by the manufacturer. Because
these jack connections are unique, using a Speaker/
Microphone that is not specified by Vertex Standard
may damage the VXA-150.
EXT DC Jack
When an external 12-Volt DC power source is available, you may connect the (optional) E-DC-5B External 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-150 directly to a source
which exceeds 15.0 Volts DC will result in damage to
the unit.

FIELD PROGRAMMING MODE
The VXA-150’s Book Memories also allow the user to store, label, and recall channel frequencies which you may want
to use frequently while the VXA-150 is in the Field Programming mode.
Memory Storage into the Book Memory
r Press and hold the PTT and LAMP switches while
turning the radio on, to activate the Field Programming Mode.
r Select the desired frequency to be stored in the Book
Memory.
r Press and hold the [MW(SPL.W)] key for 2 seconds.
The display will indicate “BOOK- ” and a channel number will blink on the LCD.
r Within five seconds of pressing the [MW(SPL.W)] key,
rotate the CHANNEL selector knob to select the desired memory channel number for storage.
r Now press and hold in the [MW(SPL.W)] key for 2
seconds; you will now see “

CE32 Programming Software Instructions
With the CE32 programming Software you can quickly and easily program the features and memories of the Vertex
Standard VXA-150 heavy duty air band transceiver from your personal computer. The CE32 Programming Software
allows custom memory files to be stored, saved, merged, and edited for convenience when planning a journey. In the
event of an accidental memory failure, transceiver memory and configuration data may be re-loaded in a matter of minutes.
The CE32 Programming Software diskette contains the following files:
m CE32.EXE - The executable programming software;
m CE32.HLP - The "Help" file used with the main program; and
m CE32.CFG - The "Configuration" file for the main program.
Before connecting the VXA-150 for programming, turn off both the computer and the VXA-150. Now connect the CT-
42A PC Programming Cable to the computer's serial port and the VXA-150 as shown in the illustration. Then it will be safe
to restart the computer; turning off the equipment during interconnection avoids damage to the electronics caused by
voltage spikes.
Insert the distribution diskette into your 3½" drive (after booting DOS), and make a copy of the diskette; use the
distribution diskette for archive purposes, and use the disk copy for programming.
Place the CE32 (copy) diskette into your 3½" drive (usually "Drive A"), and log onto this drive by typing A:[ENTER]. At
this point, you may make a directory for the CE32 software, if you like, according to standard DOS procedures (using the
MKDIR command). Load the contents of the CE32 diskette into this directory, using the COPY command (e.g. COPY A:*.
C:\ [directory name]).
Now type CE32 [ENTER] to start the program. The introductory screen will appear, and you may press any key to enter
the main screen, as shown below.
Choose the "Help" contents option from the program's Menu for assistance with program operation.
Important Note!
Do not work directly with the CE32 programming diskette. Make a copy of it and use the copy when programming the
VXA-150. Keep it and the original distribution diskette in a safe place in case you need to make another copy of it later.
