FAQ
Q. What is the proper time to use Healing Fit per day?
A. Maximum usage time is 50 minutes per session(30 minutes recommended). Recommends 1 - 3 times a day.
Q. Are there any side effects of long-term use?
A. According to many researches Micro-electric stimulation under 2mA has no side effects. Therefore our
product has developed flow a microcurrent of 0.2 - 1 mA, you can use it in safe range.
Q. How should user adjust and use the TES(Micro Electrical Stimulation) intensity level?
A. Some users may not feel any stimulation in the first few minutes of therapy. Please increase the intensity of
level from 1 to 4 slowly and once you hear the voice message indicating Level 4 is on, wait about three
minutes. If you do not feel proper stimulation after three minutes, increase the intensity one level more slowly.
Contrariwise, reduce the intensity level when you feel strong stimulation. When using for the first time, some
users may not feel irritation even if the level is raised. However, if you use it up to level 10, be careful as the
stimulation may feel too provocative.
Q. Which strength is suitable for using Healing-Fit?
A. We can not say in general becuase each individual feels different even with the same intensity. It is
recommended to use one level lower at the stage where the intensity of stimulation is felt but if electrical
stimulation is not burdensome, you can use it at that level.
TES Therapy still works even though user does not feel the electrical stimulation. Therefore, you can use
Healing-Fit at any level where the individual is comfortable.
Q. Sometimes when I'm using HEALINGFIT at a TES intensity level that's comfortable at level 5, and all of
a sudden it would feel too intense when I haven't touched the settings. Is this normal?
A. Yes, it is normal. Continuous stimulation over identical spot of skin may result the change of the contact
resistance with the skin due to the skin condition of the contact part, the stimulation effect, etc., and the
intensity of stimulation may vary. At the time, move the microelectric stimulation part to other spot slightly, or
reduce the TES intensity level.
Q. I've been using HEALINGFIT at level 7, but today it feels way too intense at just level 3. Is there
something wrong with my HEALINGFIT?
A. No. Even the same intensity of TES may feel different depending on factors such as physical condition and
contact with the skin. We recommend finding the right level of TES intensity at each use.
Q. Does TES activate while listening the music on my phone or YouTube?
A. Yes, tab the TES button shortly while you are listening the music on phone or watching youtube.
Q. There are total 5 different mode of music has inserted in the Healing-fit but only the same track is
played repeatedly. How can I change the track of it?
A. Hold the R or L button for two seconds to go to the next track when music is playing. The sound therapy
content of HEALINGFIT's Healing, Study, and Sleep Modes is set to play on single-track repeadtedely, unless
controlled by the user.

- 10 -
Q. Does the microelectric stimulation part need separate management?
A. Since skin secretions may adhere during use, so wipe with a soft cloth frequently. And when receving therapy,
there is a possibility that skin troubles may occur because the microelectric stimulation part keeps in contact
with only one place. In this case, please use it after fully recovering.
Q. It operates abnormally (volume up and down, playing the next song, mode switch, etc.) even though I
did not touch it while lying down in bed during therapy.
A. The touch button is controlled by static electricity from the human body. If the electrostatic effect of the hair
or mat is touch the button , it is possible to cause an abnormal operation.
Q. You can hear the sound from both earphones when you are listening the music, but if only the right
side of earphone operates during the voice call, is this normal?
A. It is normal that voice to be heard only from the right earphone during a call.
The microphone and speaker in the left earphone are located close to each other, so the other person's voice
from the speaker enters the microphone again and the other person can hear their voice.
To solve the issue, we have blocked the sound coming out of the left side of earphone during a call.
