CTCSS Encoder/Decoder
Subaudible (CTCSS) 50-tone Encoder and Decoder circuits are built into every VX-2500E, ensuring compatibility with modern repeater requirements.

DCS Encoder/Decoder
For applications requiring Digital Coded Squelch signalling, full-featured DCS Encoder and Decoder circuits provide leading-edge protection from false decoding.

DTMF ANI Encoder
Automatic Number Identification (ANI) via an automatic DTMF Encoder is also provided among the VX-2500E's versatile signaling capabilities.

Versatile Scanning
A wide range of set-up options are available during configuration of the VX-2500E, to ensure compatibility with the operating requirements of your system's users. Alpha-numeric Display (14 Segments x 8 Digits) The 8-digit Alpha-numeric display allows quick channel identification by the user, and is easy to read from a wide range of viewing angles.

Emergency Mode
When activated, the "Emergency" feature sends out the 5-Tone or DTMF ANI, and cycles between transmit and receive, to serve as an emergency beacon to alert the dispatcher as to the need for immediate aid.

ARTS™ Feature
The Auto-Range Transponder System, a Vertex Standard exclusive, alerts the operator when another ARTS™-equipped station (for example, a hand-held unit) moves out of communication range. You can then advise the other user to move to a better location.

Compander Included
For narrow-band channel applications, the built-in Audio Companding system compresses the voice waveform during transmission, and expands it during reception, allowing full-sounding audio despite the restricted transmission bandwidth.

5-TONE ENCODE/DECODE
The VX-2500E also has a 5 Tone Encoder and Decoder built-in. The radio can respond to an individual or group call 5 tone sequence, and can generate 5 Tone calling sequences for individual or group call facilities.

Programmable Front Panel Keys
Custom assignment of important functions to front panel keys is available at the time of programming, to provide the most ergonomically-friendly transceiver available today.

Programmable Alert Tones
Among the useful set-up options for the VX-2500E is the capability to customize the "Alert" tones generated from the transceiver, for ease of recognition by the user.

Rugged, Die-cast Construction
The VX-2500E's circuitry is housed within a die-cast aluminium enclosure, which doubles as a heat sink. This extraordinarily durable construction ensures many years of reliable operation, even in high-vibration installations.

TOT, BCLO, BTLO Features
Among the most useful protection features of the VX-2500E are the transmitter Time-Out Timer (TOT), Busy Channel Lock-Out (BCLO), and Busy Tone Lock-Out (BTLO), to ensure efficient network performance at all times.

MIL-Spec Rated (MIL 810 C/D/E)
The ultra-rugged design of the VX-2500E Series enables it to be fully compliant with the exacting specifications of MIL 810 C, D, and E, pursuant to the test procedures documented below.
