Interruption of Electrical Service
If you experience an interruption of electrical service, due to a power surge
or other factors, during normal operation of your Rumble Tuff® Electric Breast
Pump Duo, try the following:
• Unplug the AC/DC Adapter from the electrical outlet and wait for 5
seconds.
• Plug the AC/DC Adapter back into the electrical outlet.
• If the problem persists, try a different electrical outlet.
Radio Frequency Energy
This equipment generates, uses, and can radiate radio frequency energy. If
not installed properly and used in accordance with the instructions, it may
cause harmful interference with other devices in the vicinity. Try the following
steps if interference occurs:
• Reorient or relocate the device receiving interference.
• Increase the distance between the equipment.
• Connect the equipment to an outlet on a circuit different from that which
the other device(s) are connected.
• Consult the manufacturer or a field service technician of the device
receiving interference for help.
• Please understand that there is no guarantee that interference will not
occur.
Decreased Suction
If one bottle has lost suction, the problem is not in the pump:
• Make sure the Expression Collection Combo Kit is assembled correctly
(see pages 8– 12).
• Center your nipple in the Flange and make sure there is a complete seal
between the Flange and your skin.
• Press the Diaphragm firmly into the Cup and make sure there is no gap
(see page 10).
• Check the Membrane Valve and make sure that it is properly sealed and
securely seated (see page 8).
• Inspect the Membrane and Valve very closely for tears or warping. This
component is critical to achieve proper suction; even the tiniest tear will
adversely affect pump performance. If damaged, replace the Membrane
Valve with one of the spare valves provided with your Rumble Tuff Express.
