requires a separate subscription to a communications service from a service provider.  Altering 
service provider-specific settings may void the warranty.    This limited warranty does not warrant that 
the device will be free of any limitations of voice quality or service caused by (1) the services provided 
by the customer’s underlying communications service provider; or (2) interference from other radio 
frequencies or transmissions, static electricity, and other electronic devices.
