Figure 1: DP760 Package Content
Connecting DP760
To set up the DP760 DECT Repeater, please follow the steps below:
Note
Check the package before installation. If you find anything missing, contact your system administrator.

Figure 2: DP760 Back View
There are two options to connect DP760 DECT Repeater, either with the AC power or Power over Ethernet (PoE)
Connecting via AC power
1. Connect the micro-USB connector into the related port on the repeater station and connect the other end of the power
adapter into an electrical power outlet.
2. Connect the supplied Ethernet cable between the Internet port on the DP760 DECT Repeater and the Internet port in your
network or the switch/hub device port.
Figure 3: Connecting the Repeater Station
Connecting via PoE
To connect the DP760 DECT Repeater using PoE, you need to connect the Ethernet cable provided (or 3rd party network
cable) between the Network Socket on the repeater station to Ethernet port of your PoE switch/hub.
DP760 Implementation Architecture
The DP750 Base Station can support up to 5 DP760 DECT Repeater stations to extend the coverage area of the base in all
directions, including through floors and ceilings using star architecture as displayed on the following diagrams.
When a repeater powers on, it searches for signals from the base and any other repeaters registered to the same base. The
repeater will automatically connect to the first available signal.
The base can hand-off calls to the repeaters as the user moves from one coverage area to another. When connected to the
repeater, the DP720 handsets operate as it is connected to the base, and the hand-off from the base to the repeater can be
completely invisible to the end user, even during an active call.
Note
DP760 can relay up to 2 concurrent calls.

Figure 4: Star Mode Configuration
In star mode configuration, the coverage area of the repeaters should overlap the coverage area of the base station.
DP760 LED Patterns
The DP760 has 5 LED lights. Please refer to following table describing the status of each LED.

CONFIGURATION GUIDE
The DP760 can be configured via the Web GUI embedded using a Web browser. By default, DP760 is configured to obtain IP
address from DHCP server where the unit is located and can be discovered using UPnP feature (by default enabled).
Configuration via Web Browser
The DP760 embedded Web server responds to HTTP/HTTPS GET/POST requests. Embedded HTML pages allow a user to
configure the DP760 through a Web browser such as Google Chrome, Mozilla Firefox and Microsoft Internet Explorer.
Note: If DP760 has a known IP, users can access to its Web GUI by entering the IP address in their Web browser on a device
connected to same network.
Accessing the Web GUI using UPnP Feature
DP760 supports UPnP feature (by default enabled) for auto discovery by computers in same network. Please refer to following
steps to access DP760 Web GUI:
1. Power on DP760 and connect it to the network.
2. Connect a computer to same network as DP760. (The computer must be connected to the same sub-network as the
DP760. This can be easily done by connecting the computer to the same hub or switch as the DP760).
3. Access Network directory on the computer.
4. Locate DP760 – <MAC Address> device and double click on it to access Web GUI.
Figure 6: DP760 UPnP Discovery
5. Enter admin’s username and password and press Login button to access the configuration menu. (Starting HW version
1.3A the default admin username is ‘admin’ while the admin password is the random password that can be found on the
sticker at the back of the unit. For lower hardware versions; the default username and password are: admin/admin)

Accessing the Web GUI using DP750 Repeater Management Mode
The repeater management mode on the DP750 allows managing discovered / paired re peater stations and accessing the
DP760 Web GUI from DP750 Web GUI. Please refer to following steps to access DP760 Web GUI using DP750 repeater
management mode:
1. Access the Web GUI of your DP750 using the admin’s username and password. (Starting HW version 1.7A the default
admin username is ‘admin’ while the admin password is the random password that can be found on the sticker at the
back of the unit. For lower hardware versions; the default username and password are: admin/admin).
2. Navigate to DECT 🡪 General Settings and set Enable Re peater Management to Yes.
3. Press Save and Apply button, then reboot the unit to apply the new settings.
4. After finishing the reboot, access again the DP750 Web GUI.
5. Navigate to Status 🡪 DECT Repeater Status.
6. Access the discovered or paired repeater Web GUI by clicking on its IP address.
7. You will be redirected to login page of the repeater, enter admin’s username and password and press Login button to
access the configuration menu.
Saving the Configuration Changes
After users make changes to the configuration, pressing the Save button will save but not apply the changes until the Apply
button on the top of Web GUI page is pressed. Users can instead directly press the Save and Apply button. We recommend
rebooting or powering cycle the device after applying all changes.
Web GUI Access Level Management
There are two default passwords for the login page:
User Level Usern
ame Password Web Pages Allowed
