Troubleshooting
Q. When I turned on my phone, it beeped and the screen displayed:
Invalid
Battery
. What’s going on?
A. Your phone uses the Motorola E•P Charging System. This innovative tech-
nology allows your phone to communicate with the battery and tailor the
charging cycle to get the best performance possible.
If your phone can’t communicate with the attached battery, you will see:
Invalid Battery
. Check the label on the battery–if it isn’t a Motorola
original, the battery may not have the appropriate circuitry to communicate
with the phone. Otherwise, try removing and attaching the battery again.
We recommend that you use Motorola original batteries and accessories and
that you store your batteries in the protective cover when not in use.
Q. I tried to place a call and received a fast busy signal.
A. This sound means that the cellular system did not process your call. For
example, the cellular system may be overloaded with call attempts. To redial
the number, press the Smart Button or press
æ
before ending your call
attempt, or press
º
and try the call again later. See page 95 for more
information on redialing.
