The DX422s is a digital two way radio from Entel. An Ingres protection ration of IP68 means that the DX422s is completely protected against dust, whilst also being able to be submerged in water for extended periods of time. Built to military standards (MIL-STD-810 C/D/E/F/G) the DX422s is rugged and reliable, conforming to stringent standards the radio is able to withstand the rigours of shock, vibration and corrosive effects from dust and moisture.
Mixed mode operation means that the DX422s can receive both DMR Digital and Analogue without the operator having to change channel, this mixed mode capability being useful where both analogue and digital radios are being used together during a migration of systems. A keylock is also present with the DX422s in order to avoid accidental operation, this feature will lock functionality of your keys either through request of the user or after a pre-set period of time.
The DX422s makes use of a personal attack button, once activated the radio will send an alarm call to other radios in the group, whilst also emitting a high-pitched noise from the radio as a deterrent. Lone Worker is also a feature available with the DX422s, monitoring activity levels should a radio be stationary for a pre-set period of time an alert will be sent out to other radios within the group.
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 Entel DX422s.
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 Entel DX422s.
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 Entel DX422s.
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 Entel DX422s.
