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 

 

in 

Basically, the 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.
