Step by Step
Using the Telephone Efficiently
• You probably have certain colleagues or external par-
ties with whom you talk on the phone especially fre-
quently. To dial these numbers faster and more con-
veniently, you can save them on keys
(Saving station numbers for repertory dialing on
keys Æ Page 28).
• All too often you reach a busy line when dialing a
number. Amid the confusion of your working day,
it’s easy to forget to try the number again later on.
To avoid this, make it a habit to use the "Callback"
Æ Page 26 function.
