Had to replace base unit. The replacement came with one handset, but we had two handsets that were previously registered to the other base. I got the exact same model and the original two handsets don't seem to be able to register with new base. They both read "out of range or no power at base". How do I fix this without getting two new handsets. These handsets are not even a month old.

Try this to get it working.
Relocate the handset(s) closer to the main base.
Check for any lights on the base including charge, intercom, and channel lights (if applicable to the model).
Re-cradle the handset on the base for 15 seconds. Lift the handset and press PHONE.
Unplug the AC adapter from the main base unit and take out the battery from the handset. Leave it unplugged for 15 seconds. Plug the handset battery in and re-cradle the handset. Plug back the AC adapter in and wait for 15 seconds.
Try to de-register the handsets by following the steps below:
1. Using the soft keys on the base located below the base screen, press MENU
2. Press the down arrow once until BASE SETTINGS is highlighted.
3. Press the OK soft key.
4. On the base, press MUTE 3 times and FLASH twice. This will
deregister the unit.
Below are steps on how to re-register the handsets:
1. Make sure to charge the handset battery pack at least 12 hours.
2. Using the soft keys on the base located below the base screen, press MENU.
3. Use the up or down arrow keys to select DISPLAY BASE ID.
4. Press OK. The base screen will display the 15-digit Base ID
code for about 30 seconds, then the unit returns to the idle

6. Enter the 15-digit Base ID code using the number keypad.

Other products that use the 5.8GHz band can interfere with the use of this phone. These products or equipments include: radio towers, page towers, cellular Phones, other 5.8GHz cordless phones, intercoms, or monitors. If any of these are in the area, they may interfere with the performance of the phone. Try relocating the phone.

Relocate the phone out of the kitchen area. Appliances may cause interference.
If the charge light does not remain on, clean the handset and base charging contacts using a pencil eraser. If it comes on after cleaning the contacts, you may need to charge the unit for 10 hours.
Make sure that the AC power cord is securely plugged into the base. If unsuccessful, plug the unit into a different known working outlet or turn on the switch on the power strip.

Hi.
Try doing a full system power reset. This is done performing the following, simply disconnecting the power adapter won't be enough:
The
procedure above will reset the system and will re-sync handsets to
cradles. If that does not work, then some of the units comprised in the system is
defective. In that case the only way of having the system fixed is calling the manufacturer and sending the units in the system back for repair.
Regards.
Ginko.
