There are two main ways to reset power to your Guardian Repeater.
1. Disconnect power at the power supply.
2. Disconnect power at the repeater. = Open the white plastic box that houses the repeater. Disconnect the power wires. All lights on the repeater should turn off. Reconnect wires to power repeater back up. If removing or replacing repeater please be sure to CAP wires as they will still be LIVE if power is not turned off at the power supply. Note: Most repeaters do not have a battery backup. If yours does you will need to disconnect the battery too.
