The optional SRX-3 (UHF) and SRX-4 (VHF) Multi-Band
Receiver Units expand the versatility of the VX-P920/P970 Series
significantly. For example, a UHF version of the VX-920/970
Series may have the SRX-4 installed, expanding reception to
include both UHF and VHF channels so that information or
commands from a dispatch center will never be missed.

The unique Clear Voice feature provides a specialized form of
audio processing that helps the user's voice stand out more
clearly when he or she is operating in a very noisy environment.

Other Features

P25 DIGITAL MODE

P25 Digital Conventional

AMBE+2™ Vocoder

NAC (Network Access Code)

Talk Group ID

Individual ID List / Paging Group

RSSI Indicator / RSSI Warning

Mixed Mode

AES / DES Encryption Options

NAC (Network Access Code) are programmable and are
typically used to control network access but may also be used to
steer repeater operations. NAC codes are used the same way
as an analog CTCSS tone (or DCS code). There are 4096
unique NAC codes.

For superior voice quality in narrow-band, digital, P25 mode of
operation our products use the AMBE+2™ Vocoder protocol
from DVSI, Inc.

Because our products are fully TIA/EIA 102 Series compliant,

you
are assured of broad compatibility within a wide range of P25
Digital Mode systems.

Talk Group IDs (TGIDs) provide for the logical grouping of radio
users into distinct organizations and can also be used to minimize
co-channel interference. There are more than 65,000 unique
TGID addresses.

Channels can be programmed for analog only, digital only or Mixed
Mode dual Analog/Digital operation. The radio will automatically
switch to the appropriate format when it receives a call. This
capability provides seamless switching between Analog and
Digital systems saves available channel programming capacity
and simplifies user operation of the unit.

Certain models feature Liquid Crystal Displays (LCD) and
provide visual indication of receive signal level (signal strength).
All models feature an audible indication of low receive signal
strength. When received signal strength falls to a level not
suitable for reliable communications, an alert tone will sound.
This feature is useful if the unit has no display or if it is difficult
for the user to see the display during normal operation.

P25 contains special provisions for Emergency Calling. When
an "Emergency" signal is received, the radio's "Busy" LED can
provide a very bright white blinking indication while the LCD can
show the Unit ID or Alpha Tag of the unit in distress...

Data Encryption Standard (DES) is an older format system
based on a 64 bit encryption algorithm...
Advanced Encryption Standard (AES) is a newer and more
robust system based on 256 bit algorithm. Encryption Keys
Multiple encryption keys can be stored in the unit as required.

The calling station will be identified either by their Alphanumeric
Tag (if defined in the Individual ID List), or by their ID number (if a Tag
is not defined).

VERSATILITY

VX-P929/P924/P979/P974 with LCD:

Maximum 512 Channels/32 Groups

VX-P921/P971 w/o LCD: Maximum 48 Channels/3 Groups

The LCD-equipped version provides massive channel storage
capability: up to 512 channels may be programmed into as many as
32 groups. A single radio may therefore be programmed with channel
sets for a number of different jurisdictions or organizations,
ensuring seamless interoperability. The VX-P920/P970 Series without
the LCD can accommodate up to 48 channels in up to three groups.

In addition to the traditional battery saver modes, our exclusive

Intelligent Saver reduces power consumption associated with
the DSP.

Intelligent RX/TX Battery Saver

Rugged, Submersible Design

Submersible External Speaker/Microphone MH-66 Series (optional)

The VX-P920 Series portables are housed in
an ultra-rugged, impact-resistant case that is
designed to exceed U.S. MIL-STD 810C/D/E/F
standards for shock, vibration, and driving rain;
it also meets international waterproofing
standard IP55 (water jets) and IP57 (submersion
i

n water to a depth of 3 feet for up to 30 minutes).
For even more demanding environments, the
VX-970 Series version meets IP68 specifications
(submersion to 6 feet for 3 hours), and is
available via special order.

When operating in an emergency situation where immersion of
the radio and/or its accessories could occur, the optional MH-66
Series Speaker/Microphone is rated to the same submersibility
specifications as the portable itself (IP57), ensuring that your
essential communications won't be interrupted if the microphone
gets dropped into the water.

In P25 operation each transceiver can be programmed with a
unique Unit ID. There are over 16 Million possible Unit IDs
available. Additionally, using the Paging Group feature, each
unique Unit ID can be identified with an Alphanumeric Tag,
making selective calling by name is possible. What s more, if no
Paging call list has been defined, direct input of the Unit ID
number is possible, permitting direct calling of any particular user.
When receiving, the Alphanumeric Tag (Name) of the calling station
will be shown (LCD models only). If no call list has been defined,
only the transmitting station's Code number will be displayed.
The Paging Group may be subdivided into up to 15 sub-groups,
and each channel may be assigned to a sub-group in advance.

Actual Size

Reliability, ruggedness, and interoperability like never before. The VX-P920/P970 series of Vertex
Standard portables is ready to respond when you are, with a wide array of signaling capability,
along with big audio, operator and system security measures, and PC programmability for
quick

deployment. Submersible to IP57 (VX-P920) / IP68 (VX-P970) specifications, and built to
U.S. MIL-STD specifications, the VX-P920/P970 Portables are your assurance of long-term
reliability under the most difficult operating circumstances.
