One-touch overview
This telephone has  one-touch locations (speed
dial locations) where you can store the phone
numbers you wish to dial using fewer keys than
usual. You can store up to 4 digits in each
location. The steps used to dial numbers stored
in one-touch locations vary according to how you
programmed the one-touch preference. See the
PREFERENCE section and To dial a one-touch
number section of your user's manual for more
details.
You can access the first  locations using only
the one-touch buttons. To access the remaining
 locations, press [LOWER] and then the one-
touch button for the desired location.
You might wish to write the names or telephone
numbers of the one-touch entries on the directory
card, using the light gray spaces for the first 
locations and the dark gray spaces for the second
 locations.
