This battery is only intended to back up phone service in the event of a power outage. It is not intended to back up Internet service. If you have a home alarm system or home health monitoring system that relies on the telephone line to operate, you will lose access to those services during a power outage unless you have backup batteries in each piece of Cox phone equipment.
Use the following steps to install your battery backup for the following.
Unplug the power cord from the electrical outlet, and then unplug the power cord from the back of your gateway or modem.
Note: Your service is briefly interrupted.
Plug your gateway or modem power cord into the back of the battery backup, and then plug the other end into the electrical outlet.
Plug the battery backup's power cord into your gateway or modem's power port.
Result: For the Technicolor CGM4141, the battery backup LED blinks green.
