Detailed Information

The EVX-539 is a digital two way radio from Vertex Standard. IP57 Ingres protection means that the radio has a limited protection against dust, but is safeguarded against immersion in 1 meter of water for up to 30 minutes. Built to MIL-STD-810 C/D/E/F/G the EVX-539 is rugged and reliable, put through various tests in differing working environments to ensure the highest degree of reliability.

Coming as standard with a FNB-V133LI-UNI 1380mAh Li-Ion battery, this will allow for the EVX-549 to operate for 10 hours whilst in digital mode, should a longer life span be required a larger 2300mAh battery is available for purchase. A full dot matrix display is present on the front panel of the radio, this alongside a full alphanumeric keypad. 9 programmable buttons allow for customization to the users needs, ideal should you be in a dangerous working environment where an emergency function for your radio is a necessity.

The EVX-539 has an internal VOX Voice Activation function, this allows for hands free use of the radio should it be needed in the working environment. A Lone Worker alert monitors the EVX-539s activity levels, whereby if the radio is inactive for a pre-set period of time then an alert is sent to other radios within the said radios group. Key lock avoids accidental function presses from the radio, this can be done by the user or be programmed to activate after a pre-set period of time.

Features Explained

Digital Basic Privacy

Basic Privacy uses a fixed "key" which is set when the radio is programmed, of which there are 255 possible "keys". Whilst this level of privacy is technically basic encryption, it's nevertheless relatively insecure. Comparable to analogue 'inversion' scrambling, it will prevent the 'casual' listener from hearing anything, but does not guarantee against eavesdropping.

 Basic Digital Privacy is built-in to the Vertex Standard EVX-539.

Voice Activation (VOX)

Voice activation, commonly refered to as VOX, allows the user to initiate the radio to transmit, simply by using their voice. Some radios only allow VOX capability via an external audio accessory such as an earpiece or headset which is VOX-enabled or has a VOX button.

Activating Voice Activation or VOX

There are two possible ways of enabling voice activation (VOX). The first is that we can program a VOX-enable / VOX disable button on the radio. The other option is that we supply an audio accessory, an earpiece or headset, that has a VOX button. Contact us for more information about this.

Programming May Be Required

There may be programming required to activate VOX on your radio. In any event, please talk to our knowledgeable staff and we will be able to offer advice on VOX activation.

 VOX Voice Activation is built-in to the Vertex Standard EVX-539.

Channel Scanning

Channel scanning enables the user to monitor a number of channels and respond when a transmission comes through. The scan feature can usually be programmed to include or exclude channels from the scan. Scanning fewer channels makes the scan faster.

A common example is when there is a private channel and community channel programmed. This is usually the case for a shop which is a member of the local business crime reduction (or shop-watch / pub-watch) scheme. The radio would "scan", or alternate between, both channels. Normally, they might only use channel 1 for their own private use within the organisation. But when a transmission (or call) comes through on the local business crime reduction (or shop-watch) scheme channel becomes active. Then within a few seconds the radio would revert back to it's original channel 1.

Digital hybrid radios can usually scan either or both digital and analogue channels simultaneously. This allows for an extremely flexible scan facility where the user can monitor many channels across both analogue and digital modes.

 Channel Scanning is built-in to the Vertex Standard EVX-539.

Lone Worker Feature

Lone Worker is a feature found on many two way radios where it's able to send a pre-determined signal, for example a distress call or alarm, to other radios in range, Lone Worker requires some type of interaction from the radio user after a period of radio inactivity. An example of this is the radio can be set to require the radio operator to interact with his or her radio once every 30 minutes. If they fail to do so, their radio will start making an audible sound. If there is still no interaction with his or her radio within 1 further minute, a alarm will sound to other team members to tell them a team member is not responding to Lone Worker. The supervisor can then dispatch another team member to the non-reponsive team member's last known location to offer assistance.

 Lone Worker is built-in to the Vertex Standard EVX-539.
