Important:

Casing is in backup power mode. Doing so will cut off power to the Gateway. Please wait until AC
power is restored to the Gateway.
• DO NOT reboot or power cycle the Gateway while the Voice Battery Casing is in backup power
mode. Doing so will reduce the length of service time of the Voice Battery Casing.
• Place your Voice Battery Casing on a level surface in a dry location. Ensure the Voice Battery
Casing and Gateway are not located near any heat sources. DO NOT place the Gateway or the
Voice Battery Casing directly on the floor.
