VHF/UHF Portable Radios
The VX-410/420 Series of 32-Channel VHF/UHF Portables features 5 W of Power Output and a host of
leading-edge built-in features for demanding business/industry and public safety applications. Included as
standard features are Dual 2-Tone Decode, 2-Tone Encode/Decode, 5-Tone Encode/Decode, Encryption,
Voice Compander, and Multi-mode Scanning. The VX-410/420 may be programmed, by channel, for
12.5/20/25 kHz channel spacing, and for simplex or split operation.
The deluxe VX-420 version features an eight-character alphanumeric display, 4 additional programmable
keys and illuminated keypad. Both the VX-410 and VX-420 are available in Intrinsically Safe versions, and
all are built with legendary Vertex ruggedness and unmatched cost-performance.
HIGH PERFORMANCE
5 W POWER OUTPUT
The VX-410/420 Portables produce a full 5 W of power output,
with an additional selection of 1 W available for increased battery
life when higher power is not required.
12.5/20/25 kHz BANDWIDTH (PROGRAMMABLE BY CHANNEL)
When programming radios for use in different jurisdictions or
geographical regions, the VX-410/420 Portables may be
programmed, channel by channel, for 12.5, 20, or 25 kHz channel
spacing environments, with both bandwidth and deviation
automatically set according to each channel’s requirements.
LEADING-EDGE DESIGN
Crafted with care for use in areas of severe RF pollution, the
VX-410/420 Portables include excellent adjacent-channel
selectivity and immunity from Intermodulation, along with TIA-
compliant ±2.5 ppm frequency stability.
LOUD 500 mW AUDIO OUTPUT
Ideal for reception in noisy environments, the VX-410/420
Portables’ high-powered audio is coupled to a large internal
speaker, assuring solid copy throughout difficult crowd control,
fire, or sporting-event operations.
LONG-LIFE LITHIUM-ION BATTERY (1600 mAh)
The VX-410/420 Portables may be equipped with advanced
FNB-V67 Lithium-Ion Battery Packs with 1600 mAh of capacity,
for operating times of up to ten hours or more, even when using
5 W (5-5-90 duty cycle).
VERSATILITY
32 CHANNEL CAPACITY
The 32-channel capacity of the VX-410/420 Portables includes
quick access, and the channelspecific information loaded during
programming minimizes the extra
keystrokes required on competing
models. Two banks of 16 channels
each are provided for convenient
channel access.
PROGRAMMABLE "SOFT" KEYS
Two buttons on the side panel of the VX-410 may
be custom-programmed for specific functions
needed in your application. The VX-420 additionally
provides four front-panel programmable keys, for
a total of six available custom buttons.
TRUNKING OPERATION AVAILABLE
Installation of the SmarTrunk II™ module enables
use of the VX-410/420 on systems equipped
for Trunking operation.
DUAL 2-TONE AND 5/6-TONE SYSTEMS BUILT IN
For smooth integration into advanced radio systems, the VX-410/420
Portables are equipped with 2-Tone Encode/Decode, Dual 2-Tone
Decode, as well as 5/6-Tone Encode/Decode circuitry. In addition,
DTMF ANI and DTMF Paging capability is also available through
installation of the optional FVP-25 DTMF Pager Unit.
EASY USER INTERFACE
ADVANCED 8-CHARACTER ALPHANUMERIC DISPLAY
Providing an Alphanumeric Channel Label of up to 8
characters, the LCD display also provides convenient operating
function icons to provide instant recognition of radio status.
ERGONOMIC CONSTRUCTION
The carefully-engineered case construction features a gently
rounded shape for a solid grip, whether the radio is wet or dry.
Its over-sized keys are easy to activate, and the operating
firmware has been carefully shaped by years of feedback from
public safety, business, industry, and government users.
KEY LOCK
A Soft key may be programmed as a Key Lock control, to
prevent inadvertent channel change or unwanted activation/deactivation of functions. This is especially valuable in surveillance
operations, where the radio may be concealed and subject to
accidental pressure on its keys.
RADIO TO RADIO CLONE FEATURE
For quick programming of the VX-410/420 radios for an
emergency task force, the Clone feature allows copying of all
channel and configuration data from one VX-410/420 to
another, using the optional CT-27 Cloning Cable.
SECURITY
BUILT-IN ENCRYPTION
The built-in Encryption circuit provides security for your important
public safety and private security communications, and it may
be enabled at the time of radio programming by the dealer.
OPTIONAL VOICE RECORDER
The optional DVS-5 Voice Storage Unit allows you to record
and store up to 120 seconds of incoming receiver audio, ideal
for keeping an audible record of an important message. Audio may
be saved either as a one-time 2-minute recording, or a constantly
refreshing "last 120 seconds" recording may be made.
SECURITY PASSWORD FEATURE (VX-420 Series)
The VX-420 Series provides a security password feature which
can minimize the chance that your transceiver could be used by
an unauthorized party. When the password feature is activated,
the radio will ask for the four digit password to be entered when
the radio is first tur ned on. You must enter the password from
the keypad.

DURABLE CONSTRUCTION
ULTRA COMPACT
The VX-410/420 Series Portables features
and performance are housed in an ultrarugged, compact case measuring only
(W) x 4.3" (H) x 1.2" (D), and weighing less than
a pound with the standard FNB-V57 Battery.
MIL-STD RATED
Designed for use under the most demanding
conditions, the VX-410/420 Portables are
built in compliance with MIL-STD 810 D/E/F
specifications for reliable operation in environments
including shock, vibration, high and low
temperature, low pressure, rain, humidity, salt
fog, and dust.
INTRINSICALLY SAFE (IS) VERSIONS
AVAILABLE
The VX-410/420 Portables are also available
in Intrinsically Safe (IS) versions, for leadingedge communications capability in hazardous
operating situations. Included in the IS
certification for the VX-410/420 is approval
for use in dangerous hydrogen and acetylene
environments.
