This chapter provides some general troubleshooting information to help you solve the problems you
might encounter when using your DD phone.
If you require additional information or assistance with your new phone, contact your system
administrator.

Base Issue

Why doesn't the power indicator on the base station light up?
Plug the supplied power adapter to DD phone, if the power indicator doesn't light up, it should be a
hardware problem. Please contact your vendor or local distributor for help. If you cannot get a support
from them, please send a mail which includes problem description, test result, your country, and phone's
SN to Support@yealink.com.
Why does the network indicator on the base station slowly flash?
It means that the base station cannot get an IP address. Try connecting the base to another switch port, if
the network indicator still slowly flashes, please try a reset.

Register Issue

Why cannot the phone be registered to the base station?
If the network works normally, you can check the compatibility between base station and DD phone.
There are two sets of base stations, complied with the FCC and CE standards respectively. You can check
it from the back of the base station. There are also two sets of phones: US version and EU version
respectively.
The US version phone is compatible with FCC standard base station.
The EU version phone is compatible with CE standard base station.
