How can we get the existing telephone system to recognize the new handsets we have purchased? 

1) Enter the "System Reset" menu, then "Deregister HS" submenu.

2) Press volume/up or down arrow keys to select the handset ID to be e-registered from the list, then press the OK soft key. 

3) Press the OK soft key.   You will hear a confirmation tone.  When de-registration is complete, "Deregistration Complete" appears.

4) After de-registering the handset, move to "Replacing the Base Setting" below. 

Replacing the Base Setting

1) Enter the "System Reset" menu, then "Replacing Base" submenu.   "Do you want to replace Base?" appears. 

2) Press the OK soft key.   You will hear a conformation tone.  The base information will be deleted.  When replacing the base is complete, "Please Register" appears, register the handset to the new base. 

For the TRU8 models:

You should simply place them on the main base and they will register. If not then please call customer service @ 1-800-297-1023 for assistance.

Please note that not all our systems have the ability to have handsets added.  Please verify that your existing system can accept additional handsets, and that you purchase the correct model to add.
