RRP £661.00 excl. VAT

The DP3661e is the updated enhanced `e` digital model of the GP388 and GP388R models.  The form factor is a compact design with high-performance integrated voice and data.  The radio is tested to military standards for extreme ruggedness and is rated IP68 for almost complete immunity to dust and water.

Offering a large full-colour, 5-line day and night display screen with easy-to-use menu navigation keys and a reduced front keypad for extra functions.

This model does not compromise on features, with high performance integrated voice and data, and Bluetooth audio which lets you communicate without wires, the new integrated Wi-Fi enables remote software updates and indoor and outdoor location-tracking capabilities give total visibility of your resources.  There is support for trunking options and legacy analogue radio capabilities to give the customer the flexibility and adaptability required.

The series features a prominent orange emergency button on the top of the handset, which has Transmit Interrupt functionality.  An integrated accelerometer can sense if there is a man down and initiate a call for assistance. The radio is tested to military standards and is waterproof to IP68.

The new technology offers up to 16 to 27.5 hours of battery life (depending on the model of battery), this offers an increase over its competitors.

The DP3661e comes integrated with the man down (mandown and anti-movement detection), Wi-Fi and location tracking (both GPS and indoor beacons).  This model has can house an option board to further increase the options available to the custom (e.g. custom coding and bespoke behaviour).


Get all the benefits of digital, including better voice quality, better operational range and better battery life – but retain compatibility with your existing radio fleet while giving yourself the freedom to migrate to the latest technology at your own pace, this assumes the digital version is purchased, an upgrade license (to digital) is available for the analogue version.

Automatic Gain Control

This feature can automatically compensate for changes in voice level, whether you are speaking softly or loudly, turning your head, or moving the microphone further away from your mouth.

Transmit Interrupt Capability

Enables a supervisor to interrupt a DP3661e user to deliver live critical communications exactly when and where it’s needed.

Encrypted Communications

Keep your communications from being intercepted and your channels secure with 16-bit encryption, other enhancements are also available using Digital Privacy and RAS (Restricted Access to System).

Lone Worker

DP3661e can help protect those working on their own by regularly prompting the user to press a button on the radio.  If the user does not respond within a specified length of time, a supervisor or dispatcher is notified that there may be a problem.  A dedicated emergency channel can be utilised with radios automatically selecting this channel during an emergency call.

Man Down

This uses the integrated accelerometer and automatically sends an alarm signal if the radio handset is tipped over for over a programmable amount of time. The unit also supports the anti-movement feature.

Text Messaging

Ability to send pre-set messages via the user menu and side keypad buttons.

Voice Announcements

DP3661e can be configured to have voice announcements; battery level, channel selection and other functions can have standard or custom voice announcements. E.g. Channel one could now be announced as “Operations Channel” with channel two being “Emergency Channel”, great for users who have poor vision or the environmental condition are poor (night time etc).  This feature also enables the radio unit to remain in the case or clipped to a belt during channel selection.

What we think

Jason from the Service Team: “ This is a hard one to comment on, similar to the DP4600 it has a reduced keypad.  Design could be improved upon but as usually the engineering is very good.  Option for a 3rd party option board makes this radio potentially a very flexible tool, the display is great but loses flexibility with no full keypad.  Like the DP3441e performance is very good along with the options and features.  I think for majority of users and for similar money I would have opted for the DP4801e with the SL2600 a very close second.  Cons – the lower line of buttons (OK and Back) are too low on the case to use safely with one hand, better to redesign the speaker/speaker area to release space lower down.
