.
Q. I tried to place a call but received an alternating high/low tone.
A. This sound means your call did not reach the cellular system. Most likely,
you dialed the number too soon after turning the phone ON. Wait until the
NS indicator disappears before placing a call.
An alternating tone may also indicate that your phone’s signal is blocked.
Make sure the antenna is fully extended and move clear of any obstructions,
like bridges, parking garages, tall buildings, etc.
Q. My phone started beeping, and the display says: 1 Call Unanswered .
What happened?
A. Someone tried to call you while you were in an area where the cellular sig-
nal was weak. Press
Ç
to clear your display, extend your phone’s antenna,
and avoid obstructions like tunnels, parking garages and tall buildings
whenever possible.
Q. My phone was stolen. What should I report and to whom?
A. Report a stolen phone to the police and to your Service Provider (the com-
pany that sends you your monthly cellular service bills).
