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, try the following:
● Unplug the AC/DC Adapter cord from the electrical outlet and wait for five seconds.
● Plug the AC/DC Adapter cord back into the electrical outlet.
● If 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:
● Reorient or relocate the device receiving interference.
● Increase the distance between the equipment.
● Connect the equipment into an outlet on a different circuit from that which the other
device(s) are connected.
● Consult the manufacturer or a field service technician of the device receiving interference
for help.
●
There is no guarantee that interference will not occur.
Decreased Suction
If it feels like the suction has decreased, try the following:
● Make sure the Breast Pump is assembled correctly
(see Assembly Instructions pages 8-13).
○ Inspect the One-Way Valve for any tears or pinholes. This component is critical to
achieving proper suction. If damaged, replace the One-Way Valve with one of the spare
valves that is provided with your Rumble Tuff
®
Electric Breast Pump.
● Detach the Tubing and Tubing Adapter from the back of your Electric Breast Pump and place a finger
over the Tubing Adapter Inlet.
○ If you do feel suction, the Electric Pump Base is operating properly.
○ If you do NOT feel suction or feel that the suction has decreased to an unexpected strength; contact
Rumble Tuff Customer Service for warranty service (see Page 32).
