3. Safety Information
Please read and understand all safety instructions before using this product. Failure to follow these instructions may result in electric shock, fire, or personal injury.
- Indoor Use Only: This extension cord is designed for indoor use. Do not use it outdoors or in wet conditions.
- Proper Grounding: Always connect the extension cord to a properly grounded 3-prong outlet. Do not remove the grounding prong.
- Avoid Overloading: Do not exceed the cord's electrical rating of 13 amps / 125 volts / 1625 watts. Overloading can cause overheating and fire.

4. Setup and Installation
- Identify the Outlet: Locate a standard 3-prong 120V AC wall outlet where you need to extend power.
- Connect the Flat Plug: Insert the flat, right-angle male plug (NEMA 5-15P) of the extension cord into the wall outlet. The low-profile design allows for furniture to be placed closer to the wall.
- Connect Your Device: Plug the power cable of your electronic device into the female receptacle (NEMA 5-15R) of the extension cord. Ensure a secure connection.
- Route the Cable: Route the extension cord in a way that avoids tripping hazards and prevents it from being pinched or damaged.

5. Operation
Once properly connected, the Cable Matters extension cord operates as a direct extension of your wall outlet. Simply power on your connected device as usual.
- Ensure the total power draw of all connected devices does not exceed the cord's maximum rating (13A/125V/1625W).
- Do not daisy-chain multiple extension cords together.
6. Maintenance
The Cable Matters extension cord requires minimal maintenance.
- Cleaning: Disconnect the cord from the power source before cleaning. Wipe with a dry, soft cloth. Do not use liquid cleaners.
- Storage: When not in use, store the cord in a cool, dry place, away from direct sunlight and moisture. Avoid tightly coiling the cord to prevent damage.
- Regular Inspection: Periodically check the cord and plugs for any signs of wear, fraying, or damage. Replace the cord if any damage is observed.
7. Troubleshooting
If you experience issues with your extension cord, refer to the following common troubleshooting steps:
- No Power to Device:
- Ensure both the extension cord's plug and the device's plug are fully inserted into their respective receptacles.
- Verify that the wall outlet is functional by plugging in another known working device directly.
- Check if a circuit breaker has tripped.
- Cord Feels Warm:
- Immediately disconnect all devices.
- Ensure the total wattage of connected devices does not exceed the cord's rating.
- Ensure the cord is not covered or obstructed, allowing for proper heat dissipation.
- Loose Connection:
- If the plugs feel loose, discontinue use. A loose connection can generate heat and pose a fire hazard.
If problems persist, contact Cable Matters customer support.
