The Lone Worker feature is designed to emit an alarm for

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.

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.

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.

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.

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.

ANI Encoding and Decoding (MDC-1200

, GE-Star

, and

DTMF (Encode): optional VME-100 or VMDE-200 required)

VERSATILITY

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.

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.

Fleet and network operation are enhanced by the built-in DTMF

ANI/Paging circuit.

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.

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.

For operation in systems requiring Companding, the VX-

920/970 Series portables include both Wide- and Narrow-band

Companding circuitry, programmable channel by channel.

The VX-920/970 Series can transmit a 2-Tone paging call,

and can receive 2-Tone calls using different tone

combinations.

DURABLE CONSTRUCTION

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).

Rugged, Submersible Design

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.

Submersible External Speaker/Microphone

MH-66 Series

(optional)

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.
