VERSATILITY
VX-929/924/979/974 with LCD:
Maximum 512 Channels/32 Groups
VX-921/971 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-920/970 Series without the LCD can accommodate
up to 48 channels in up to three groups.
CTCSS / DCS Encode and Decode
High-performance Encoder/Decoder circuits for both
CTCSS and Digital Code Squelch are provided, for access
to tone/code controlled systems. DCS is ideal for crowded
RF environments, providing superior immunity from false
opening of the squelch.
DTMF ANI / DTMF Paging
Fleet and network operation are enhanced by the built-in DTMF
ANI/Paging circuit.
2-Tone Encode and Multiple 2-Tone Decode
The VX-920/970 Series can transmit a 2-Tone paging call,
and can receive 2-Tone calls using different tone
combinations.
User Selectable Tone (VX-927/924/979/974)
One of the front panel's "programmable" keys may be
designated so as to allow the user to select a CTCSS or
DCS tone from a pre-defined Tone Table.
Scan: Channel Scan, Priority Scan, Dual Watch,
Follow-me Scan, Follow-me Dual Watch, and TA Scan
The VX-920/970 Series provides unmatched flexibility in its
scanning features. Designed to optimize operation in a wide
variety of system environments, these scanning capabilities
ensure that you never miss an important call.
Compander (Wide and Narrow Band)
For operation in systems requiring Companding, the VX-
920/970 Series portables include both Wide- and Narrow-band
Companding circuitry, programmable channel by channel.
Lone Worker
The Lone Worker feature is designed to emit an alarm for
30 seconds when the Lone Worker Timer (programmed by the
dealer) has expired. If the user does not reset the timer by
pressing the PTT switch, the radio switches to the
Emergency mode.
RX / TX Battery Saver
When engaged, the Receive-mode Battery Saver rapidly
pulses the portable on and off, reducing current consumption
and extending battery life. If a call is received, the Battery
Saver is disengaged, and normal operation resumes. On
transmit, the Battery Saver will reduce transmitter power,
thus extending operating time, when you are within close
range of a strong repeater or dispatch center.
Programmable Function Keys
Customization of feature access
is easily accomplished at the
time of programming, thanks to
the "programmable" keys that
may be assigned functions
needed most in your operating
environment.
PC Programmable
All channel and other configuration data may be uploaded
to the portable by the dealer in a matter of minutes, allowing
efficient setup of a fleet of radios when rapid deployment is
required.
ANI Encoding and Decoding (MDC-1200 ® , GE-Star ® , and
DTMF (Encode): optional VME-100 or VMDE-200 required)
Automatic Number Identification, triggered by the pressing
of the PTT key, is available in the most popular industry-
standard formats, via the optional VME-100 (for Encoding
only) or VMDE-200 (for Encoding and Decoding) module.
DURABLE CONSTRUCTION
Rugged, Submersible Design
The VX-920 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).
VX-970 Series
Special Order Version
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.
Submersible External Speaker/Microphone
MH-66 Series
(optional)
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.
