P25 DIGITAL MODE
3
Ideal for reception in noisy environments, high-powered audio of
the VX-P820/P870 Series is coupled to a large internal speaker,
assuring solid copy throughout difficult crowd control, fire, or
sporting-event operations.

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.
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.
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
In addition to the traditional battery saver modes, our exclusive
Intelligent Saver reduces power consumption associated with the
DSP.
Intelligent RX/TX Battery Saver
VX-P829/P824/P879/P874 with LCD:
Maximum 512 Channels / 32 Groups
VX-P821/P871 w/o LCD:Maximum 16 Channels / 1 Group
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-P820/P870 Series
without the LCD can accommodate up to 16 channels in a single
memory group.
Rugged, Submersible Design
Submersible External Speaker/Microphone
MH-66 Series (optional)
The VX-P820 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 in water to a
depth of 3 feet for up to 30 minutes). For
even more demanding environments, the
VX-P870 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.
