The DP4801e is a digital two way radio from Motorola. Available for both UHF and VHF frequencies, the DP4801e also has the advantage of having GPS, Bluetooth and Wi-Fi Integrated. Coming as standard with a 1400mAh NiMH battery, this will allow for up to 10 hours of operation in digital mode. Should additional battery life be needed, a 1650mAh Li-Ion standard or smart IMPRES battery can be purchased at an added cost.
Built to IP68 standards the DP4801e has a full ingress protection against dust, this whilst also being able to be fully submerged under water for long periods of time. MIL-STD-810 C/D/E/F/G means that the DP4801e is rugged and reliable, put through the Motorola Accelerated Life Test this radio will last in some of the harshest working environments.
Due to the nature of environment the DP4801e can work in, the radio has an amass of safety features. VOX Voice Activation allows for the Motorola DP4801e to be used hands free, whilst Transmit Interrupt stops any current conversations in order to broadcast an important message, whether this be for an emergency situation or simply to relay new instructions to the fleet. Lone worker helps to ensure the safety of workers, should a radio be inactive for a set period of time then an alarm will be raised to all other members of the fleet.
The Inclusion of GPS allows for the Man Down feature as a software download. Man down is a function that when a radio is laid on its side for a certain period of time will sound a beacon to all other radios, signalling its GPS to the base station so that the injured party can be found and helped quickly should a serious injury occur.
Bluetooth conectivity allows audio accessories to be connected to the radio wirelessly. Most manufacturers offer Bluetooth earpieces whcih are only suitable for their products. This is because they generally only want you to choose their accessories, but also because of the different ways their radios work.
Bluetooth is built-in to the Motorola DP4801e.
Two Way Radio GPS
GPS (global positioning system) is a mechanism which a device can use a number of in-range satellites to trangulate it's position and transmit that position back to the repeater or base station. This enables the supervisor to more effectively manage team members by knowing their current location.

GPS is designed for outdoor tracking. See "Indoor tracking" for indoor solutions.
GPS is built-in to the Motorola DP4801e.
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 Motorola DP4801e.
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 Motorola DP4801e.
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 Motorola DP4801e.
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.
Voice Activation (VOX) is built-in to the Motorola DP4801e, but a VOX-enabled audio accessory, such as an earpiece or headset, may be required.
Man Down provides remote monitoring of workers by detecting if their radio is upright, or if the radio is on it's side assumes there may be a problem. Radios which support Man Down are fitted with an accelerometer (or similar device) which allows them to detect the orientation of the radio. If somebody slips or falls, they are likely to be on their side, Man Down will automatically detect this, activate and transmit an alert to call for help from a supervisor or other team members. This works is almost the same way as your smart phone which knows if you have it positioned portrait mode or landscape mode. See this video below to see how the a works.

Man Down is an optional extra for the Motorola DP4801e.
