Ensure the correct voltage is selected on the battery backup to match the requirements of your CPAP machine or other connected devices. Refer to your EASYLONGER battery backup manual for specific instructions on adjusting voltage levels.
• Continuous Power: The adapter provides continuous power to charge the battery backup. Once the battery is fully charged, the adapter will maintain its charge.

6. Maintenance

• Cleaning: Disconnect the adapter from all power sources before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or aerosols.
• Storage: Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures when not in use. Avoid wrapping the cable too tightly around the adapter.
• Cable Care: Do not bend, twist, or pull the cables excessively. This can damage the internal wiring.
