- Place the silicone diaphragm onto the linker cover, ensuring a secure seal.

4.3 Flange Sizing
Selecting the correct flange size is crucial for comfort and efficient milk expression. The ABP-1508 includes 24mm flanges and inserts for 21mm, 19mm, and 17mm. To determine your correct size, measure the diameter of your nipple (not the areola) at its base after a pumping session. The flange tunnel should be 2-4mm larger than your nipple diameter.
- 17mm Insert: For nipple diameters approximately 13-15mm.
- 19mm Insert: For nipple diameters approximately 15-17mm.
- 21mm Insert: For nipple diameters approximately 17-19mm.
- 24mm Flange: For nipple diameters approximately 20-22mm.

5. Operating Instructions
5.1 Power On/Off
Press and hold the power button on the motor unit to turn the pump on or off. The LCD screen will illuminate, displaying the current mode and intensity level.
5.2 Modes and Intensity Levels
The ABP-1508 offers 3 distinct modes and 9 adjustable intensity levels to customize your pumping experience:
- Stimulation Mode: Mimics a baby's quick, light suckling to initiate milk let-down.
- Expression Mode: Provides slower, stronger suction to efficiently express milk once let-down occurs.
- Massage Mode: A gentle, rhythmic pattern designed to comfort and stimulate milk flow.
Press the 'M' button to cycle through the modes. Use the '+' and '-' buttons to adjust the suction intensity within each mode (levels 1-9). The pump has a memory function that will recall your last used settings.

5.3 Pumping Session
Place the assembled pump unit directly onto your breast, ensuring your nipple is centered in the flange tunnel. Wear a supportive nursing bra to hold the pump securely in place. Begin with Stimulation Mode to encourage let-down, then switch to Expression Mode. Adjust the intensity to a comfortable yet effective level. A typical pumping session lasts 10-15 minutes.

The ABP-1508 is designed with ultra-quiet technology, operating at a low noise level (typically below 40dB), comparable to a library whisper. This allows for discreet pumping in various environments, including at night or in public.

6. Maintenance and Cleaning
