How to use

Connect the power supply to the mains using a compatible AC power cord, then attach the DC output plug to the device’s power inlet designed for external adapters. Ensure the device is powered off before connecting or disconnecting the adapter to prevent electrical transients. Verify that the adapter’s rated output meets the device’s power requirements and that the input voltage matches the local mains supply within the 100V–240V range.

Recommendations

Place the adapter in a well-ventilated area away from liquids and heat sources. Use the original or a certified replacement AC cord and inspect connectors periodically for wear. For optimal performance, do not cover the adapter during operation and avoid using it in excessively dusty or humid environments.
