Lone Worker
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-response team member's last known location to offer assistance.

Lone Worker is built-in to the Motorola GP640.
Digital Basic Privacy
Digital Basic Privacy ensures that any communications made using your two way radios are protected against the potential for eavesdropping. Although this level of protection is very basic it still offers a degree of protection against your communications being listened in on by unwelcome parties.
Basic Privacy uses a fixed key which is set when the radio is programmed. There are 255 potential keys to be chosen from, this meaning that this is still a fairly simple privacy option for your devices. In order for an eavesdropper to listen in to your conversations they would require your exact frequencies, whilst also knowing the exact key that you have used for privacy.
The main reason for purchasing licensed two way radios is the privacy that they offer over license exempt devices. When communicating in work environments where there is the potential for sensitive information to be passed over the airwaves, having at least a basic level of privacy ensures that due diligence has been taken to keep work communications in house.

Basic Digital Privacy is built-in to the Motorola GP640.
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. Should a transmission be found, your radio will stop and pause giving the operator the chance to respond to the transmission before continuing its cycle through the selected channels.
When programming your radio, it is possible to include or exclude channels from the scan, this allows for channels of highest priority to be added meaning that staff members never miss an important transmission. Channel scanning is an ideal choice in environments where updates are frequently given, this allowing for all of your members of staff to remain alert to changing conditions.
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 Motorola GP640.
Voice Activation (VOX)
VOX (voice-operated exchange), more commonly known as Voice Activation, allows the two way radio's microphone and PTT button to be activated by simply speaking into the radio.
How To Use VOX
Most two way radios' voice activation feature only works via an external VOX capable earpiece or headset. Once connected, you simply start speaking and the two way radio will automatically initiate the transmission. When there is no longer any audio coming via your earpiece or headset, the two way radio automatically disengages the PTT.
Activating VOX
Most business grade licence exempt two way radios allow activating the voice activation feature via a button combination on the radio; or by simply plugging in a vox capable earpiece or headset. However, some more complex two way radios, such as our licensed two way radios will require some reprogramming.
VOX Drawbacks
Since VOX works by listening out for audio via the attached accessory, background noise that's near to the sound of a human voice will also activate it. That means practically anything can activate the voice activation.

Voice Activation (VOX) is built-in to the Motorola GP640, but a VOX-enabled audio accessory, such as an earpiece or headset, may be required.
FREE Radio ID Labels Supplied & Applied
For no extra cost, we supply labels with all of our radios.
Our labels are unique in that they have a space where you can write on them with a sharpie-type permanent marker. You can either use this space to write a radio number or apply a dymo label for example. These labels are 100% free of charge
