[ARC20x User Guide p20: 11 Handset Registration]
To register a new handset:

1. Press and hold the HANDSET LOCATOR on the base unit until you hear Registration tone (repeated 'beeps')
2. On the handset, press the PROG then the UP or DOWN button to display "REGISTER"
3. Press the PHONE/OK
   -> The display shows "BS 1234". If any of these numbers is steady (not flashing), then the handset is already registered to that base unit.
   
4. Press 1 to select base unit number 1
   -> The display shows "BASE PIN _ _ _ _"
5. Key in the system PIN (default 0000) and press the PHONE/OK
   -> The display shows "WAIT _ _ _ _" for a few moments, while the handset searches for a base. Then it shows a list of handset numbers which are still free on the base unit.
   (For example, "1 34 6" indicates that numbers 1, 3, 4 and 6 are free; 2 and 5 are already assigned to other handsets.)
6. Key in a free handset number
   -> After a moment, the display should show the handset's name and number.

• Try again, making sure you begin step 2 as soon ans Registration tone starts.

SOURCE: my cordless phone says

With the phone in standby, press MENU/SELECT on the base.
Move the cursor to select the Register Handset menu, and then press MENU/SELECT. Handset Registering will appear.
On the handset, press and hold # until the handset beeps and displays Handset Registering.
When the handset has registered to the base, the LCD will display Registration Complete then show the handset ID number.
If the display shows Registration failed, repeat the process again.
Note: If a handset has ever been registered to a base, reset the handset before you register it to a new base
