DP760 User Manual
Version 1.0.15.6
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.
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.

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)

DP760 User Manual
Version 1.0.15.6
Accessing the Web GUI using DP750 Repeater Management Mode
The repeater management mode on the DP750 allows managing discovered / paired repeater 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

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

DP760 DECT REPEATER ASSOCIATION WITH DP750
After factory reset, DP760 will be set to “Auto-region” mode. In this mode, the three LEDs of right side keep
quick blinking, then the DP760 will search the base signal in the current environment to auto associate with
it and then auto switch to the same region (EU, US or BR) of the base station.
Enabling Repeater Mode on DP750
Before associating the DP760 DECT Repeater to your DP750 Base Station, you should firstly enable the
repeater mode on your base station. Please refer following steps to enable the repeater mode on the DP750
base station:
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 Repeater Mode to Yes.
Figure 10: Enable Repeater Mode
3. Press Save and Apply, then Reboot the base to apply the new settings.
DP760 DECT Repeater Association
After enabling the repeater mode on DP750 Base Station, you can easily associate it with your DP760
DECT Repeater using one of the following methods:
• Auto Association
• Manual Association
• Use DP750 Repeater Management to associate DP760
P a g e | 35
DP760 User Manual
Version 1.0.15.6
Note: Using auto/manual association methods, the DP760 repeater will not be listed on DP750 “DECT
Repeater Status” page even if “Repeater Management Mode” is enabled on DP750.
Auto Association
To auto associate your DP760 DECT Repeater with DP750 Base Station:
1. Please put the DP760 DECT Repeater close to DP750, then power on the DP760.
2. After the DP760 finish booting, the association LED will be blinking to indicate that the repeater
is searching for nearby base stations.
Note: If all the LEDs remain on, it indicates that the DP760 Repeater has successfully associated with a
DP750 Base and ready for use. You may need to dissociate it before continuing (Please refer to [DP760
DECT REPEATER DISSOCIATION]).
3. Open subscription on your DP750 Base Station using one of following methods:
• Rebooting the Base station.
• Long press on page/subscribe button on the back panel of DP750 for 7 seconds.
• Access DP750 Web GUI and press subscribe button .
4. The DP760 DECT Repeater will automatically pair to DP750. Upon successful association with the
DP750 Base station all LEDs will turn ON and the repeater status will be updated as following.
