The telephone is
providing feedback
after you enter
(press) a numeric
digit from 1 to 9. This
occurs, for example,
when registering your
phone for the first
time (see
Registering

in
Chapter

indicator “winks out”
the digit you pressed
(for example, if you
pressed 4, Call
Appearance Line a’s
indicator winks four
times).
Each subsequent
digit you press
causes Call
Appearance Lines a
and b to alternate
winks.
