- Connect to Power Outlet: Insert the 2-prong plug of the power cable into a standard, grounded electrical wall outlet.
- Verify Connection: Ensure both ends of the cable are securely connected.
4. Operating Instructions
Once the power cable is correctly connected to your device and a power outlet, your device should receive power. Turn on your device using its power button or remote control as usual.

To ensure the longevity and safe operation of your power cable, follow these maintenance guidelines:
- Cleaning: Disconnect the cable from both the device and the power outlet before cleaning. Wipe the cable with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Storage: When not in use, store the cable in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid tightly coiling the cable to prevent damage.
- Inspection: Periodically inspect the cable for any signs of damage, such as cuts, fraying, or bent prongs. If any damage is observed, discontinue use immediately and replace the cable.
6. Troubleshooting
If your device is not receiving power after connecting the EPtech power cable, consider the following:
