Uniden Cordless Telephon Owner's Manual page 36

The memory locations in the handset are not limited to phone numbers. You can also
store a group of numbers (up to 20 digits), that you need to enter once your call
connects. This is referred to as Chain Dialing.
An example of this is a bank account number. Store the special number in the Phonebook
location (refer to "Storing Phone Numbers, Names, Distinctive Rings and Speed Dial" on
page 27). Once you have called your bank, and when you are prompted to enter the
account number, press /RocketDial/ and use + or - to select the number in the
Phonebook location, then press select/ch.
