mate talk time by tones for the first five minutes. (a
short monotone
signal will sound every minute and a
double beep tone will be heard after approximately 5

SID MANAGEMENT
(NAM OPTION)
This feature enables you (by NAM option) to take advan-
tage of a family of SID groups. This is a group of cellular
systems in cities that your carrier owns
or has special
billing arrangements with. Your close family SID's (like
brothers and sisters) will be billed at the same rate as
your home
bone Rilling PN will be indicated as "Home"
(i.e.
both
NOSVC| and ROAM!) are off) on your display. More
distant. family ve (like cousins) will be billed at a
preferred
rate. Your
phone will display solid
ROA
when using these groups of systems in their cities. When
flashing
is displayed, you are using a SID system
that is not included in the NAM
assigned groups.

, you will need
