Optimum Voice Battery Back-Up

This valuable accessory provides uninterrupted voice service including emergency 911 services during a power failure. When electrical power is not available, the modem will automatically switch to the battery back-up for power. When electrical power is restored, the modem will switch back to electrical power and the battery back-up will recharge right in the modem. No intervention is required.

Important: The battery backup does not provide power to a cordless phone. To ensure uninterrupted service during a power outage connect a standard "wired" phone directly to the back of the modem.
