Power Outage:
In the event of a power outage, your cordless telephone will not operate. The cordless tele-
phone requires electricity for operation. You should have a telephone that does not require
electricity available for use during power outages.
VoIP service may not work during a power outage, or when the Internet connection fails or
becomes overloaded.
If your power is out or your Internet connection is down, be aware that your VoIP service may
not work. Consider installing a backup power supply, maintaining a traditional phone line, or
having a wireless phone as a backup.
