BATTERY BACKUP POWER NOTICE
During an electrical service power outage, your CMS telephone service will be affected unless there is a backup power source. The absence of a backup power source means access to 911 and other emergency services will be unavailable. The absence of internet connectivity during a power outage also causes your telephone service to be unavailable.
You are not required to purchase a battery backup solution.
