9. Troubleshooting
Here are answers to common questions and issues first-time users may encounter:
It won't start!
Remove the tab from the battery compartment and press the power button on the front of your device. Then, tap the '+' button on the side of the toner where your probe is plugged in to get your program to start and for your toning unit to begin delivering current. The '+' button starts the program and raises the current, all the way to 99mA's as needed. Keep tapping!
Why is it stopping at 10mA's?
Your probe functions as both a sensor and conductor. Both metal rings or panels on each probe must contact the skin to release current. If the toner doesn't receive a signal from both conductors, it won't release current, which can occur if the probe is in the air or wires are not fully connected. Ensure the probe pegs are firmly pressed into the waterproof tubes for a complete connection. Always insert the probe into your body before powering on. Adjust the mA only on the side where the probe is plugged in. The side without a probe will stop at 10mA.
No feeling?
The vaginal canal has very few nerve endings, with most clustered at the vaginal opening and cervix. It is normal to have low internal sensation. Your toner will go all the way to 99mA's. Just keep tapping the '+' button until you feel the current at a strong, comfortable level. Aim for at least 30mA's.
Feeling less intense over time?
Great! That means your body is getting stronger. You can feel free to increase the mA's to the new level you are comfortable at.
What are these extra wires?
Your kit comes with one wire for your probe to connect to and a spare for future use. Hang on to it for later!
What is a kegel toner?
Electric kegel toners are battery-powered muscle stimulators that direct current through a probe to the pelvic floor. This form of exercise is automatic and does not require the user to attempt to contract their muscles. The toner does the work for you!
Is it safe?
K-fit has undergone rigorous FDA registration. Electric muscle stimulation for pelvic floor strengthening has been studied for years by independent doctors and researchers. The current will not harm your tissue, and even the strongest workout will only cause muscle soreness, similar to any strong gym workout.
How does it work?
K-fit has designed eight unique programs that target your muscles in different ways. Varied speeds, strengths, and lengths of stimulation all force your muscles to respond by building new muscle fibers. Electric stimulation directed by the probe forces the surrounding muscles to contract rapidly. In a single second, you can perform multiple contractions. In one 20-minute session, you can perform thousands of contractions.
When will I see results?
Results depend on many factors, including age, weight, previous tissue disruption, scarring, and consistency of use. Most users begin to see noticeable results within a few weeks with consistent use.
