Package Contents

• 1 x Nippon Power DVSW-2000 Universal AC/DC Power Adapter
• 6 x Interchangeable Adapter Plugs

Setup Instructions

Before connecting the adapter to your device, it is crucial to set the correct voltage and select the appropriate adapter tip.

1. Identify Device Requirements

Consult your device's instruction manual or power input specifications to determine the required DC voltage (V), current (mA), and polarity (positive or negative center pin).

Caution: Using incorrect voltage or polarity can permanently damage your device.

2. Select the Correct Voltage

Locate the voltage selector switch on the side of the adapter. Use a small tool (e.g., a flat-head screwdriver or coin) to slide the switch to the desired voltage setting (3V, 4.5V, 6V, 7.5V, 9V, or 12V).

3. Choose the Appropriate Adapter Tip

From the 6 included adapter plugs, select the one that physically fits your device's power input jack. Ensure a snug fit. The tips are designed for various barrel connector sizes.

4. Set Polarity (If Applicable)

Some adapter tips allow for polarity reversal. If your device requires a specific polarity (e.g., center positive or center negative), ensure the chosen tip is configured correctly. Refer to your device's manual for polarity requirements. The DVSW-2000 adapter itself has a fixed output polarity, but some tips might offer a way to reverse it by flipping the tip. If the tips do not offer this, assume the adapter has a standard polarity (typically center positive).

Note: The product description and images do not explicitly detail how to change polarity on the tips. If your device requires a specific polarity, verify the adapter's output polarity matches your device's requirement before connecting.

Operating Instructions

1. Connect Adapter Tip: Firmly attach the selected adapter tip to the output cable of the DVSW-2000 power adapter.
2. Connect to Device: Insert the adapter tip into your electronic device's power input jack.
3. Plug into Outlet: Plug the DVSW-2000 power adapter into a standard AC wall outlet (90V-240V, 50/60Hz).
4. Verify Operation: Check if your device powers on or begins charging. If not, re-verify voltage, tip, and polarity settings.
5. Disconnect: To disconnect, first unplug the adapter from the wall outlet, then remove the tip from your device.

Maintenance and Care

• Keep the adapter clean by wiping it with a soft, dry cloth. Do not use liquid cleaners or solvents.
• Store the adapter and its tips in a cool, dry place when not in use.
• Avoid bending or crimping the power cord excessively.
• Regularly inspect the adapter and cables for any signs of damage. Discontinue use if damage is observed.

Troubleshooting

Device Does Not Power On/Charge

• Check Voltage: Ensure the voltage selector switch is set to the correct voltage required by your device.
• Check Adapter Tip: Verify that the correct adapter tip is securely attached and fully inserted into your device's power jack.
• Check Polarity: Confirm that the polarity of the adapter matches your device's requirements.
• Check Power Outlet: Test the wall outlet with another known working device to ensure it is supplying power.
• Check Current Requirement: Ensure your device's current requirement (mA) does not exceed the adapter's 2000mA output.

Adapter Overheats or Emits Odor

• Immediately unplug the adapter from the wall outlet and disconnect it from your device.
• This may indicate an overload or internal fault. Do not continue to use the adapter.

Electrical Noise (e.g., with Audio Devices)

• Some power adapters may introduce electrical noise, particularly noticeable with sensitive audio equipment.
• If experiencing significant noise, this adapter may not be suitable for your specific audio application.
