Conditions that may aect your TENS+EMS SUPER DUO-System
Since the stimulator is a battery-operated electronic System, its output
performance and safety may be aected greatly in extreme humidity.
Therefore, it is very important to keep the stimulator dry to ensure the safety and
performance of the stimulator.

STEP BY STEP OPERATION GUIDE FOR TRAINING
PREPARING THE SKIN FOR RUNNING A SESSION
Proper preparation of the skin covered by the electrodes allows more stimulation to
reach targeted tissues, prolongs electrode life, and reduces the risk of skin
irritation. After connecting the lead wire(s) to the stimulator, use the following steps
to prepare your skin at the electrode placement sites:
1. Determine the placement sites for the electrodes.
2. Wash the area with mild soap and water (do not use alcohol). Rinse and dry
thoroughly.
3. Trim excess body hair from the area with scissors (do not shave).
4. Optionally, apply skin prep to the area to form a protective barrier on your skin.
Apply, let dry, and apply electrode as directed. This will both reduce the chance
of skin irritation and extend the life of your electrodes.
5. When removing electrodes, always remove by pulling in the direction of hair
growth.
6. It may be helpful to apply skin lotion on electrode placement area when not
wearing electrodes.
Step by step operation guide for training
Connecting the Cable to The Device
1. Connecting the lead wire to the electrodes before applying to the Skin.

14
Inserting/Changing the Batteries
1. Open the battery compartment at the back of the device by pushing the
battery cover labelled “Open” downward (this area features raised marks for
easy identication).
2. Insert 3 AAA (1.5 V) batteries in the battery compartment; make sure to match
up the symbols (+/–).
3. Close the battery cover by carefully placing the stud into the slot in the rear
area and sliding it upward, applying slight pressure.
4. Follow the same procedure when replacing the battery at a later date.
Note: for important precautions regarding the batteries, please be informed:
• Alwaysuseonly3x1.5V(AAA)batteries.
• Keepawayfromchildren.
• Donotrecharge.
• Donotshort-circuit.
• Donotthrowintoare.
• Pleaserecycle.Donotdisposeofoldbatterieswithyourhouseholdwaste;
dispose of them safely at your recycling centre or business where the batteries
were purchased.

Choice of the appropriate mode
The mode you choose determines the kind of work that is imposed upon the
stimulated muscles. Choose the mode that is appropriate to your needs or gives
you the greatest pleasure.
For TENS programs:
When using any of the 8 programs for pain relief always start with the lowest
intensity and gradually increase the
level of intensity until you feel a “tingling” sensation. All programs are dierent
and therefore feel dierently.
You may try all 8 programs in the beginning and choose one that feels pleasant.
Never increase the intensity to a level so that it hurts, always stay under the point
of discomfort. Start with short sessions of 5 or 10 minutes until your body gets
used to the stimulation.

For EMS programs:
Whenusingthedeviceformusclestimulation(EMS)anyofthe8programsmay
be used. The intent is to cause a muscle to contract, and then release.
All 8 programs will achieve contraction and vary mainly by the rate and duration
of the contractions. As with any exercise regiment, start out slowly with low
intensity levels for a warm-up (5~10min). You may increase intensity level and
treatment time as you progress with your muscle performance. Use the device
regularly over a longer period of time as to maintain the benet you may have
gained during “exercise”.
