6. Operating Instructions

6.1 Getting Started

1. Ensure the breast pump is fully charged.
2. Assemble the pump as described in Section 5.2.
3. Place the assembled pump inside your nursing bra, ensuring the silicone breast cover is centered over your nipple. Use the bra adjustment buckle if needed for a secure and comfortable fit.
4. Press and hold the Power/Mode button to turn on the pump. It will typically start in Massage Mode.

6.2 Understanding the Modes

Figure 5: 4 Working Modes & 12 Suction Levels

• Massage Mode: This mode is designed to stimulate milk let-down. It features a faster rhythm with smaller suction power. Ideal for initiating milk flow and alleviating breast discomfort.
• Pumping Mode: Once milk flow begins, switch to this mode for stronger, sustained suction. It simulates a baby's natural sucking rhythm for efficient milk expression.
• Frequency Conversion Mode: This mode uses a unique rhythm of nine long suctions followed by one short suction. It helps stimulate milk ducts and promote milk secretion, especially useful in the early postpartum period.
• Automatic Mode: This mode transitions between Massage and Pumping rhythms. It starts with stable suction and gradually increases the suction level (gear) every 15 seconds until it reaches the 9th gear, adapting to your body's response.

6.3 Adjusting Suction Levels

Each mode has 12 adjustable suction levels. Use the 'Gear Shift +' and 'Gear Shift -' buttons on the control panel to increase or decrease the suction intensity to your comfort level.

6.4 Hands-Free Pumping

The MY-378 is designed for ultimate convenience. Once properly positioned in your bra, you can continue with light activities such as reading, working, or caring for your baby while pumping. The low noise operation (<51dB) ensures discretion.

6.5 Auto Power-off

The pump is equipped with an auto power-off feature that will turn off the device after 30 minutes of continuous operation. This is a safety feature and helps conserve battery life.

8. Cleaning and Maintenance

Proper cleaning and sterilization are crucial for hygiene and the longevity of your breast pump.

8.1 Cleaning Instructions

4. Rinse thoroughly under clean running water.
5. Air dry on a clean drying rack or use a clean cloth.

8.2 Sterilization

Sterilize all milk-contacting parts at least once a day, or as recommended by your healthcare provider. Methods include:

• Boiling: Place parts in a pot of boiling water for 5 minutes.
• Steam Sterilizer: Use a microwave or electric steam sterilizer according to the manufacturer's instructions.

• Maintain Hygiene: Always prioritize cleaning and sterilization of milk-contacting parts to ensure the safety of your breast milk.
• Experiment with Modes: Don't hesitate to try all four modes and adjust suction levels to find what works best for your body and milk flow. Many users find starting with Massage Mode helps initiate let-down before switching to Pumping Mode.
• Charge Regularly: To avoid interruptions during pumping sessions, ensure your pump is charged after each use or before a planned session.
• Read the Manual: A thorough understanding of your pump's features and functions, as detailed in this manual, will enhance your overall experience.
