3920 wireless telephone 1

[retiredtelco]

I have a 3920 wireless telephone in an abusive environment. The handset got throw against a wall. It is trashed. My question is, I have a spare handset, how do I marry the spare handset to the old base unit.

Taken from the manual

Register a Handset to the Base
Perform this procedure if you add or replace a handset.
Before a handset can be used in your system, it must be registered to the
cordless base. The handset that came with your system was preregistered
at the factory.
Perform the following steps if you add or replace a handset:
1 Install the handset’s battery and charging cradle.
2 Charge the handset for several hours.
3 Press and hold menu.
4 Using the Vol + and - buttons on the side of the handset, select “Register.”
5 Press menu. The handset displays the prompt “Are You Sure.”
6 Using the Vol + and - buttons, select “Yes.”
7 On the base, press the registration button for three seconds. The indicator
will begin to flash. After a few seconds, the handset will prompt you for the
base’s registration PIN. The factory-set PIN is “1234.”
8 Enter “1234.” The handset and base will register to each other. You can
now use the handset with that base.

The truth is just an excuse for lack of imagination.
