Setup Instructions

1. Identify Device Voltage and Polarity: Before connecting, check your device's power input requirements. Note the required voltage (e.g., 5V, 9V, 12V) and polarity (center positive [+] or center negative [-]). This adapter's default polarity is center positive, outer negative. If your device requires center negative, a polarity reversed cable (sold separately, search "B07PM24TKV" on Amazon) is necessary.
2. Select the Correct DC Connector Tip: Choose the appropriate DC connector tip from the provided set that matches your device's input port. The kit includes various sizes and types, such as standard barrel connectors, Micro USB, and an LED Terminal Connector.

3. Attach the Selected Tip: Firmly attach the chosen DC connector tip to the output cable of the universal adapter.
4. Set the Output Voltage: Locate the voltage selector switch on the adapter unit. Use the included key or a small flat-head tool to rotate the switch to the desired voltage (5V, 6V, 7.5V, 9V, 12V, 13.5V, or 15V). Ensure the voltage matches your device's requirements precisely to prevent damage.
