Connecting DP755
To set up the DP755 DECT Cordless VoIP Base Station, please follow the steps below:
DP755 Back View
You have two options for power and network connection of the base station: AC power or Power over Ethernet (PoE).
Connecting via AC power
1. Connect the micro-USB connector into the related port on the base 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 base station and the Internet port in your network
or the switch/hub device port.
Connecting via PoE
To connect the base station using PoE, you need to connect the Ethernet cable provided (or 3rd party network cable) between
the Network Socket on the base station to Ethernet port of your PoE switch/hub.
Setting up DP730/DP722 Handsets
Please follow below steps to insert batteries into the Handsets:
Open the battery compartment cover.
For DP730: Inset Li-ion battery with the electrodes in the bottom left corner.
For DP722: Insert AAA batteries with correct polarity (+ / -).
Close the battery compartment cover.
Note
Check the package before installation. If you find anything missing, contact your system administrator.
Note
For better signal range, we recommend installing DP755 with LED side facing toward the usage area. Ceiling mount is
recommended for better coverage.
