With this old model of phone you don't have the soft keys to scroll through the directory like the newer models have.
In order to check the system speed dials you will need to check them manually:
System Speed Dial #'s
LNR/SPD key and the system speed # 00~79
Station Speed Dial #'s
LNR/SPD key and the system speed # 80~99
This will dial the # and/or display the name associated with the speed dial.
In order to program them refer to this manual:Elite IPK Features and Specs
Look under Speed dial-Station or System.
