4. Operating Instructions
The PowerQuest 303 is designed for simple operation. Once connected, it continuously provides power conditioning and surge protection to your connected devices.
4.1 Power On/Off
Use the main power toggle switch on the front panel to turn the unit on or off. When the switch is in the "ON" position, power is supplied to all 12 outlets.
4.2 Indicator Lights
The front panel features two indicator lights:
- Protection On: This green LED indicates that the non-sacrificial surge protection circuit is active and functioning correctly.
- Overvoltage Protection: This red LED illuminates if the Extreme-Voltage Shutdown circuit has been activated due to an excessive input voltage (above 140VAC). If this light is on, the unit has temporarily disconnected power to protect your equipment.
