yes, I am still hoping for an answer. My secondary phone will not charge and is unusable until someone can tell me how to load the default delta file ( whatever that means...). thanks for your help.

Reset the controllers as follows:

 

  • Remove the rechargeable batteries from each of the cordless handset(s).
  • Unplug the main base power cord from the wall outlet. (Not to be confused with the remote charging base)
  • Unplug the other end of the power cord from the main base.
  • (If the main base also has a main backup battery, remove the battery.)
  • ----- Wait 20 minutes. -----
  • (The timing is very important --- 15 minutes is too short and 30 minutes may be too long. If you miss the time window, plug the unit back in for 5 minutes and start over.
  • Re-connect the power cord to the main base.
  • Re-install the rechargeable battery in one of the cordless handsets.
  • Place the cordless handset in the main base.
  • Re-connect the main base power cord to the wall outlet.
