1. Introduction
This manual provides essential information for the safe and effective use of your OMNIHIL Extra Long 10FT L-Shaped C7 Power Cord. This high-quality replacement power cord is designed to provide reliable power to compatible electronic devices, such as the Ridgeway QS-2715BR, that utilize a C7 (figure-8) inlet.
The L-shaped connector design allows for flexible placement and reduces strain on the power inlet, making it ideal for tight spaces. With a length of 10 feet, it offers extended reach for various setup configurations.

2. Setup and Connection
The OMNIHIL L-Shaped C7 Power Cord is designed for simple plug-and-play operation. Follow these steps to connect your device:
- Identify the Device's Power Inlet: Locate the C7 (figure-8) power inlet on your electronic device. Ensure the device is turned off before connecting the power cord.
- Connect the C7 End: Insert the L-shaped C7 connector end of the OMNIHIL power cord firmly into the device's C7 power inlet. The L-shape allows for a flush fit against walls or in confined spaces.
- Connect the Wall Plug: Insert the 2-prong wall plug end of the power cord into a standard 120V AC wall outlet. Ensure the outlet is easily accessible.
- Power On Device: Once both ends are securely connected, you may turn on your electronic device.

3. Operating Instructions
This power cord functions as a direct replacement for your original C7 power cord. Once properly connected, it will supply the necessary AC power from the wall outlet to your compatible electronic device. No specific operational steps are required for the cord itself beyond proper connection.
4. Maintenance and Care
- Cleaning: Disconnect the power cord from both the device and the wall outlet before cleaning. Wipe the cord and connectors with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Storage: When not in use, coil the cord loosely to prevent kinks and damage. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Inspection: Periodically inspect the cord for any signs of damage, such as cuts, fraying, or bent prongs. If any damage is observed, discontinue use immediately and replace the cord.
- Avoid Over-bending: Do not sharply bend or crimp the cord, especially near the connectors, as this can damage the internal wiring.
5. Troubleshooting
If your device is not receiving power after connecting the OMNIHIL power cord, consider the following:
- Check Connections: Ensure both the C7 connector and the 2-prong wall plug are fully and securely inserted into their respective ports.
- Test Outlet: Plug another known working device into the wall outlet to confirm the outlet is supplying power.
- Inspect Cord: Visually inspect the entire length of the power cord for any visible damage (cuts, kinks, exposed wires). If damaged, do not use.
- Device Compatibility: Verify that your device specifically requires a C7 (figure-8) power cord. This cord is not compatible with 3-prong (grounded) power inlets or other connector types.
If the issue persists after these checks, the problem may lie with the electronic device itself or require further assistance.
