Important Safety Information

Ensure the power supply is used with devices that match its voltage (12V DC) and current (up to 5A) specifications. Incorrect voltage or current can damage your device or the adapter.
Verify the DC port dimensions (5.5 x 2.5 mm) and polarity (inner positive, outer negative) of your device before connecting.
This product is a power adapter, not a battery charger. Do not attempt to charge batteries with it.
Avoid exposing the power supply to water, moisture, or extreme temperatures.
Do not disassemble or modify the power supply. Refer servicing to qualified personnel.
Unplug the power supply from the wall outlet when not in use for extended periods.

Setup and Compatibility

Determining Compatibility

Before connecting the power supply, it is crucial to confirm its compatibility with your device. Follow these steps:

Check Device Voltage: Locate the specification label on your device. The working voltage must be 12V DC. This adapter is not compatible with AC 12V or voltages lower or higher than 12V DC.
Check Device Current: Determine the maximum current your device requires. It should be equal to or less than 5A (e.g., 0.5A, 1A, 2A, 2.5A, 3A, 3.5A, 4A, 4.5A, 5A). If your device requires more than 5A, this adapter is not suitable.
Verify DC Port Dimensions: The power input port of your device must match the adapter's DC port size: 5.5 mm (outer diameter) × 2.5 mm (inner diameter).
Confirm Polarity: The inner core polarity of your device's power input port should be positive (+), and the exterior polarity should be negative (-).

Connecting the Power Supply

Ensure your monitor or compatible device is turned off.
Connect the DC output barrel connector (5.5 x 2.5 mm) of the power supply to the power input port of your monitor.
Connect the AC power cord to the power supply unit.
Plug the AC power cord into a standard 100-240V AC wall outlet.
A green LED indicator on the power supply unit will illuminate, indicating it is receiving power.
You can now power on your monitor or device.

Operating Instructions

The Gonine 12V 5A Monitor Power Supply Cord operates automatically once connected correctly. The green LED indicator on the adapter unit confirms that power is being supplied. No further user interaction is required for its basic operation.

Maintenance

Keep the power supply clean and free from dust. Use a dry, soft cloth for cleaning.
Store the power supply in a cool, dry place when not in use.
Avoid bending or crimping the cables excessively, as this can damage the internal wiring.
Regularly inspect the cables and connectors for any signs of damage. If damage is found, discontinue use and replace the unit.

Troubleshooting

Problem	Possible Cause	Solution
Monitor not powering on.	Power supply not connected properly. Wall outlet not providing power. Incompatible voltage/current. Incorrect DC plug size or polarity. Faulty power supply or monitor.	Ensure all connections are secure. Test the wall outlet with another device. Re-verify device compatibility (voltage, current, plug size, polarity) as per the "Setup and Compatibility" section. If issues persist, contact customer support.
Green LED indicator is off.	No power from the wall outlet. Loose AC power cord connection. Internal fault in the power supply.	Check wall outlet. Ensure AC cord is firmly seated in the adapter and wall. If still off, the power supply may be faulty.
Power supply feels excessively hot.	Overload (device drawing too much current). Poor ventilation. Internal fault.	Immediately disconnect. Re-verify device current requirements. Ensure the adapter is in a well-ventilated area. If overheating persists with compatible devices, discontinue use.
