Before You Begin

Battery Pack 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 titling the Belt Clip outward.

・ To remove the battery, turn the radio off and remove protective cases. Slide the Battery

Pack Latch on the bottom of the radio, and then slide the battery downward and out from
the radio while unfolding the Belt Clip.

Caution!: Do not attempt to open any of the rechargeable Li-Ion packs, as they could
explode if accidentally short-circuited.

Low Battery Indication

・ As the battery discharges during use, the voltage gradually becomes lower. When the

battery voltage becomes to low, substitute a freshly charged battery and recharge the
depleted pack. The TX/BUSY indicator on the top of the radio will blink red when the
battery voltage is low.

・ Avoid recharging Li-Ion batteries often with little use between charges, as this can

degrade the charge capacity. We recommend that you carry an extra, fully-charged pack
with you so the operational battery may be used until depletion (this “deep cycling”
technique promotes better long-term battery capacity)

SAFETY TRANING INFORMATION

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.

FCC OET Bulletin 65 Edition 97-01 (1997) Supplement C, Evaluating Compliance with FCC Guidelines
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
Frequency Electromagnetic Fields, 3kHz to 300 GHz.
ANSI/IEEE C95.3-1992, IEEE Recommended Practice for the Measurement of Potentially Hazardous
Electromagnetic Fields-RF and Microwave.

(!) WARNING: This radio generates RF electromagnetic energy during transmit mode. This radio is
designed for and classified as Occupational Use Only, meaning it must be used only during the course of
employment by individuals aware of the hazards, and the ways to minimiz e such haz ards. T his radio is not
intended for use by the General Population in an uncontrolled environment.

(!) CAUTION: To ensure that your exposure to RF electromagnetic energy is within the FCC allowable
limits for occupational use, always adhere to the following guidelines:

* 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 l east 1 inch (2.5cm) 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 (PTT) 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 PTT button or by using the VOX headset, model VC-25.

* DO NOT transmit when the radio is used in Body Worn configuration with the following

accessory: belt-clip (CLIP-18).
It must be used ONLY for (1) there is a 4 cm distance from the body during transmitting, (2)
monitoring purposes, using the speaker only and (3) for carrying purposes.

* Always use Vertex Standard authorized accessories.

The information listed above provides the user with the information needed to make him or her aware of
RF exposure, and what to do to assure that this radio operates with the FCC RF exposures limits of this
radio.

Electromagnetic Interference/Compatibility
During transmissions, this radio generates RF energy that can possibly cause interference with
other devices or systems. To avoid such interference, turn off the radio in areas where signs are
posted to do so.
Do not operate the transmitter in areas that are sensitive to electromagnetic radiation such as
hospitals, health care facilities, aircraft, and blasting sites.

FCC LICENSE INFORMATION
This radio operates on communications frequencies which are subject to FCC (Federal
Communications Commission) RUles and Regulations. FCC Rules require that all operators using
Private Land Mobile radio frequencies obtain a radio license before operating their equipment.

Operating Manual

Operation

Preliminary Steps

・ Install a charged battery pack onto the transceiver, as described previously.
・ Screw the supplied antenna onto the Antenna jack. Never attempt to operate this

transceiver without an antenna connected.

・ If you have a Speaker/Microphone, we recommend that it not be connected until you are

familiar with the basic operation of the VX-350 series.

Operation Quick Start

・ To turn the top panel’s VOL/PWR knob clockwise to turn on the radio on.
・ Turn the top panel’s CH selector knob to choose the desired operating channel.
・ Rotate the VOL/PWR knob to set the volume level. If no signal is present, press and hold

in the Soft key assigned to MONOTOR for more than 1 second; 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 in the Soft key assigned to MONITOR for more than 1 second (or press

the MONITOR key twice) to quiet the noise and resume normal (quiet) monitoring.

・ To transmit, monitor the channel and make sure it is clear.

THIS IS AN FCC REQUIREMENT!

・ To transmit, press and hold the PTT switch. Speak into the microphone area of the front

panel grill (lower right-hand corner) in a normal voice level. To return to the Receive
mode, release the PTT switch.

・ If a Speaker/Microphone is available, remove the plastic cap and its two mounting

screws from the right side of the transceiver, then insert the plug from the
Speaker/Microphone into the MIC/SP jack; secure the plug using the screw 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.
Note: Save the original plastic cap and its mounting screws. They should be re-installed
when not using the Speaker/Microphone.

Key Functions

The VX-350 series has [side1] key, [side2] key, [A], [B], [C] and [D] function keys, and
both the LCD version and non-LCD version provide programmable Side 1 and 2
switches. These “Soft” key functions can be customized (set to other functions), via
programming by your VERTEX STANDARD dealer, to meet your
communications/network requirements. Some features may require the purchase and
installation of optional internal accessories. The possible Soft key programming features
is illustrated below, and their functions are explained next chapter. For further details,
contact your VERTEX STANDARD dealer.
For future reference, check the box next to each function that has been assigned to the
Soft key on your particular radio, and keep it handy.
