Detailed Information

The DP3661e is a digital two way radio from Motorola. Available for both UHF and VHF frequencies, the DP3661e has a channel capacity of 1000. A large full colour 5-line display and a partial keypad makes up the front of the radio, whilst also having 4 programmable buttons to improve ease of use and increase efficiency of the operator.

Built to IP68 standards the DP3661e is completely ingress protected against dust, whilst also being able to be immersed under water for long periods of time. MIL-STD-810 D/E means the DP3661e is rugged and reliable, passing the Motorola Accelerated Life Test this radio will be long lasting in a variety of working environments.

GPS, Bluetooth and WiFi are all integrated into the Motorola DP3661e. Features such as VOX Voice activation are present with the radio, this allowing for hands free communication should it be needed. Over the air programming allows for all radios within a fleet to be upgraded wirelessly, meaning no downtime in operation is suffered when it comes to updating firmware for the DP3661e.

Safety features such as Lone Worker are a standard in the DP3661e, this feature sends an alert out to other radios within a fleet should someone be inactive for a selected period of time. Transmit Interrupt allows current communications of all radios within a fleet to be broken for an announcement, whether this be for emergency purposes or in order to relay new instructions to the time.

Features Explained

Bluetooth

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 DP3661e.

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 Demonstration Video

For more information on GPS, download this Motorola GPS information sheet.

GPS is designed for outdoor tracking. See "Indoor tracking" for indoor solutions.

 GPS is built-in to the Motorola DP3661e.

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 DP36611e.

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 DP3661e.

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 Motorola DP3661e.

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 DP3661e, but a VOX-enabled audio accessory, such as an earpiece or headset, may be required.

Man-down Feature

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 Demonstration Video

The Accelerometer Science

The science which allows man-down to work 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 DP3661e.
