Q. I tried to place a call but received an alternating
high/low tone. What does this mean?
A. This sound means your call did not connect to the network. 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.

You could see this message for several reasons. The most likely one is that

E•P technology. We recommend that you use only Motorola original
batteries and accessories and that you store your batteries in their
protective covers when not in use.
