IMPORT ANT NOTICE!
FCC RF Exposure Compliance Requirements for Occupational Use Only:
This Radio has been tested and complies with the Federal Communications Commission (FCC) RF exposure
limits for Occupational Use/Controlled exposure environment. In addition, it complies with the following
Standards and Guidelines:
FCC 96-326, Guidelines for Evaluating the Environmental Effects of Radio-Frequency Radiation.
r
FCC OET Bulletin 65 Edition 97-01 (1997) Supplement C, Evaluating Compliance with FCC Guidelines
r
for Human Exposure to Radio Frequency Electromagnetic Fields.
ANSI/IEEE C95.1-1992, IEEE Standard for Safety Levels with Respect to Human Exposure to Radio
r
Frequency Electromagnetic Fields, 3 kHz to 300 GHz.
ANSI/IEEE C95.3-1992, IEEE Recommended Practice for the Measurement of Potentially Hazardous Elec-
r
tromagnetic Fields - RF and Microwave.
This radio is NOT approved for use by the general population in an uncontrolled environment. This
¦
radio is restricted to occupational use, work related operations only where the radio operator must
have the knowledge to control its RF exposure conditions.
When transmitting, hold the radio in a vertical position with its microphone 1 to 2 inches (2.5 to 5
¦
cm) away from your mouth and keep the antenna at least 1 inch (2.5 cm) away from your head and
body.
The radio must be used with a maximum operating duty cycle not exceeding 50%, in typical Push-to-
¦
Talk configurations.
DO NOT transmit for more than 50% of total radio use time (50% duty cycle). Transmitting more
than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded.
The radio is transmitting when the red LED on the top of the radio is illuminated. You can cause the
radio to transmit by pressing the P-T-T button.
Always use Vertex Standard authorized accessories.

CONTROLS & CONNECTORS (RIGHT SIDE
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.

Precautions
r This apparatus is capable of two-way communi-
cation 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.
r 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-150 directly to a
source which exceeds 15.0 Volts DC will result
in damage to the unit.
r Do not dispose of the Ni-Cd Battery Pack in a
fire. Do not carry a Ni-Cd 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-Cd
pack.
r Although the VXA-150 is designed to be water
resistant, the enclosure is not “waterproof.” Do
not allow the radio to become submersed in water, and do not expose it and/or its Ni-Cd Battery
Pack to water spray under pressure.
Battery Installation and Removal
¦ To install the battery, hold the transceiver with
your left hand, so your palm is over the speaker
and your thumb is on the top of the Belt Clip.
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 re-
move 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
unfolding the Belt Clip.
Do not attempt to open any of the recharge-
able Ni-Cd packs, as personal injury or damage to the Ni-Cd pack could occur if a cell or cells
become accidentally short-circuited.
