Emergency Alert Configuration
This device is designed to receive wireless emergency alerts from
the Commercial Mobile Alerting System (CMAS); which may also be
known as the Personal Localized Alerting Network (PLAN). If your
wireless provider has chosen to participate in CMAS/PLAN, alerts are
available while in the provider's coverage area. If you travel outside
your provider's coverage area, wireless emergency alerts may not be
available. For more information, please contact your wireless
provider.
