WARNING! FCC RF EXPOSURE REQUIREMENTS
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:
qFCC 96-326, Guidelines for Evaluating the Environmental Effects of Radio-Frequency Radiation.
qFCC OET Bulletin 65 Edition 97-01 (1997) Supplement C, Evaluating Compliance with FCC Guidelines for Human
Exposure to Radio Frequency Electromagnetic Fields.
qANSI/IEEE C95.1-1992, IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency
Electromagnetic Fields, 3 kHz to 300 GHz.
qANSI/IEEE C95.3-1992, IEEE Recommended Practice for the Measurement of Potentially Hazardous
Electromagnetic Fields –RF and Microwave.
o This radio is NOT approved for use by the general population in an uncontrolled exposure environement.
This radio is restricted to occupational use, work related operations only where the radio operator must
have the knowledge to control his or her RF exposure conditions.
o When transmitting, hold the radio in a vertical position with its microphone 2 inches (5 cm) away from your
mouth and keep the antenna at least 2 inch (5 cm) away from your head and body.
o 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.
o SAR compliance for body-worn use was only demonstrated for the specific belt-clip Part Number (#
BA0102700112KA). Other body-worn accessories or configurations may NOT comply with the FCC RF
exposure requirements and should be avoided
o Always use Vertex Standard Authorized Accessories.

BEFORE YOU BEGIN
Battery Pack Installation and Removal
rTo 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. Care-
fully mate the battery’s four insertion slots with
their corresponding alignment tabs on the trans-
ceiver case, while tilting the Belt Clip outward.
Proper alignment occurs with the battery pack
offset about 1/2 inch from the top edge of the
battery compartment.
rGuide the pack on to the tabs with a slight inward
pressure, then slide the battery pack upward, un-
til it locks in place with a “Click.”
rTo remove the battery, turn the radio off and re-
move any protective cases. Slide the Battery
Pack Latch on the bottom of the radio toward
the front panel while sliding the battery down
about 1/2 inch. Then lift the battery out from the
radio while unfolding the Belt Clip.
Do not attempt to open any of the recharge-
able Lithium-Ion packs, as they could ex-
plode if accidentally short-circuited.
Low Battery Indication
As the battery discharges during use, the voltage
gradually becomes lower. When the battery voltage
reaches 6.0 volts, it is time to substitute a freshly
charged battery and recharge the depleted pack. The
LED indicator on the top of the radio will blink red
when the battery voltage is low (6 Volts or lower).
Tilt the Belt Clip
Insert the Battery Pack
Caution
Danger of explosion if battery is replaced with
an incorrect battery. Replace only with the same
or equivalent type.

OPERATION
Preliminary Steps
rInstall a charged battery
pack onto the transceiver,
as described previously.
rScrew the supplied an-
tenna onto the Antenna
jack. Never attempt to op-
erate this transceiver
without an antenna con-
nected.
rIf you have a Speaker/Mi-
crophone, we recommend that it not be connected
until you are familiar with the basic operation of
the VX-900.
Quick Start
rTurn the top panel’s
VOL/PWR knob
clockwise to turn on
the radio on.
rTurn the top panel’s CH
selector knob to choose
the desired operating
channel. A channel
name will appear on the
LCD. If you want to se-
lect the operating chan-
nel from a different Memory Channel Group, press
the Soft key (assigned to the Memory Group Up or
Down function) to select the Memory Channel
Group you want before selecting the operating chan-
nel. A Group name will appear on the LCD when-
ever the Soft key is pressed.
Note: Some models are programmed so that the
operating channels are selected by the Soft key
and the memory channel group is selected by the
CH selector knob. For further details, contact your
VERTEX STANDARD dealer.

rRotate the VOL/PWR
knob to set the volume
level. If no signal is
present, press and hold
in the MONITORbut-
ton (under the PTT
switch) more than 2
seconds; background
noise will now be
heard, and you may
use this to set the
VOL/PWR knob for
the desired audio level.
Press and hold the
MONITORbutton more than 2 seconds (or press
the MONITOR button twice) to quiet the noise
and resume normal (quiet) monitoring.
rTo transmit, press and
hold the PTT switch.
Speak into the micro-
phone area of the front
panel grille (above the
[D]key) in a normal
voice level. To return
to the Receive mode, release the PTT switch.
OPERATION
rPress the Soft key (if assigned to the Scan func-
tion) or switch the TOGGLE Switch to the as-
signed “Scan” position (when so programmed by
your dealer) to start the scanner. The scanner rap-
idly steps through each of the dealer-programmed
channels, looking for incoming calls.
rPress the TOP SEL
key (on the top panel)
or SIDE SEL key (the
top button on the left
side) to activate one of
the preprogrammed
functions which may
have been enabled at
the time of program-
ming by the dealer.
Similarly, when using
the 16-key version, the
[A], [B], [C], and [D]
function keys may ac-
tivate one of these features, if programmed by
the dealer. See the next section for details regard-
ing the available features.

VX-900OPERATING MANUAL 7
OPERATION
rSwitch the top panel’s
TOGGLE switch to
the [A], [B], or [Cen-
ter] position to activate
one of the pre-pro-
grammed functions
which may have been
enabled at the time of programming by the dealer.
When this switch is in the [A(left)], [B(right)],
or [Center] position, the feature programmed (by
your dealer) to that switch position will be acti-
vated. See the next section for details regarding
the available features.
rPress the DTMF keys on the telephone keypad
while pressing the PTT switch to send DTMF
tones (16-key version only).
rIf a Speaker/Microphone is available, remove the
plastic cap and its two mounting screws from the
right side of the transceiver, then align the con-
nector of the Speaker/Microphone on the trans-
ceiver body; secure the connector pin using the
screws supplied with the Speaker/Microphone.
Hold the speaker grille up next to your ear while
receiving. To transmit, press the PTT switch on
the Speaker/Microphone, just as you would on
the main transceiver’s body, and speak into the
microphone on a normal voice level.
Note: Save the original plastic cap and its
mounting screws. They should be reinstalled
when not using the Speaker/Microphone.
