6. Instructions for Use
1. Connect both ends of the
electrode cable with two electrode
pads.
2. Plug the electrode cable into one
of the output jacks located at the top
of the unit. Either side A or B.
3. Use a damp towel to wipe the
skin before you place the pads to
remove any body oil, cosmetics or
dirt. Should the pads be soiled, both
their adhesiveness and reusability
will be reduced.
4. Peel off the protective film from
the pads.
5. Apply the pads to the areas of the
body you want to massage.
6. Press the On/Off button on the
top right hand side of the unit to
enable the display. The mode
selected will flash on the LCD
screen and the timer will
automatically be set to 20 minutes.
7. Click the mode area to select your
preferred mode from the 24 modes
available.
8. Increase the intensity when
changing to a new mode until
stimulation is strong but
comfortable. Intensity will return to
the lowest setting automatically
when selecting a new mode or sub-
mode. Press “+” or “-“ buttons on the
side of the unit or tap “+” or “-“ on

the screen to strengthen or reduce
the intensity output. The ideal power
output depends on your personal
comfort.
9. Tap the timer to adjust the
treatment time. The time is
automatically set at 20 minutes
when the device is powered on.
Each tap will increase the timer by
10 minutes. When the timer ends,
the unit will power off.
10. Press the bottom silver button to
lock the LCD screen once all
settings have been chosen. The
unlock symbol will change to a lock
symbol on the screen. This will
ensure your settings aren’t
accidentally changed during
treatment. Press the same button
again to unlock the screen.
11. If you need to turn off the device
during treatment, hold in the power
button to power down the device.
12. Take off the electrode pads and
return them to the protective films
for storage and reuse.
Notes:
As responses will vary person-to-
person, begin with shorter treatment
times and increase as necessary.
Never put two pads directly together
to avoid a possible short.
You will not feel stimulation unless
both pads are applied to the
treatment area so a current can be
formed between the pads.
Never connect this product with a
common headphone jack.
The USB port is only used for
charging, do not connect to any
other device. Only use the charger
supplied by the manufacturer.
7. Stimulation Diagram

All modes function on a combination
frequency to treat muscle, nerve or
joint pain so choose the mode that is
most comfortable for you and your
pain type.

8. Maintenance and Storage
1. Unplug the electrode cables from
the output jacks after using.
2. Cover both pads with the
protective films for storage. This will
prevent the pads from becoming
soiled or dirty and maintain the
adhesive for more uses. You may
rinse the pads with cool water and
let air dry if they become dirty. This
may allow a temporary restoration of
the adhesive for additional uses
before the pads need to be
replaced.
3. To keep the unit clean, use a soft
dry cloth for dust or a damp cloth for
dirt. Do not use cleaning solutions.
4. Do not use or store the device
where there are magnetic or electric
wave fields such as 1V sets or
speakers.
5. Do not place the device in areas
of high temperature, high humidity,
or under direct sunlight.
6. Keep the device out of reach of
children.
