UNDERSTANDING TENS STIMULATION

TENS stands for Transcutaneous Electrical Nerve Stimulation. It works by delivering gentle electrical pulses through electrode pads placed on the skin.

When the device is turned on, the electrodes send small electrical signals that create a tingling, buzzing or pulsing sensation at the surface of the skin. The intensity can be adjusted so you can choose a level that feels comfortable.

Many users enjoy TENS stimulation because it creates a noticeable yet controllable sensation that can be easily adjusted using the device controls.

The electrode pads can be placed on many areas of the body depending on where stimulation is desired. Because the device has dual output channels, two sets of pads can be used at the same time if preferred.

Electrical stimulation technology like this has been widely used for many years in professional health and sports environments. Portable devices allow people to explore similar stimulation technology in a convenient format designed for home use.

UNDERSTANDING INTERFERENTIAL (IF) MODE

IF stands for Interferential stimulation.

This mode uses two electrical wave patterns that interact with each other to create a slightly different stimulation sensation compared with standard TENS pulses.

Many users describe IF stimulation as feeling:

• Smoother
• More flowing
• Less sharp than a traditional buzzing sensation.

Because the wave patterns interact with each other, the stimulation can feel slightly different across the treatment area compared with the more consistent pulse pattern produced by standard TENS mode.

Some people simply prefer the feel of IF stimulation, while others prefer the traditional buzzing sensation of TENS. Having both modes available allows you to experiment and find the stimulation style that feels most comfortable for you.

CHOOSING BETWEEN TENS AND IF MODE

Both modes deliver electrical stimulation through the electrode pads, but they produce different stimulation patterns.

TENS Mode

• Creates a noticeable buzzing or tingling sensation
• Produces a consistent pulse pattern

IF Mode

• Produces a smoother, flowing stimulation sensation
• Uses interacting wave patterns

Many users simply explore both options and choose the mode that feels most comfortable for their personal preference.

EMS MODE - ELECTRICAL MUSCLE STIMULATION

EMS stands for Electrical Muscle Stimulation. In this mode, the device delivers electrical pulses through the electrode pads that create rhythmic muscle contractions beneath the skin.

When EMS mode is active, you may notice the muscles gently tightening and relaxing in a repeating pattern. Many users describe the sensation as feeling like the muscles are being lightly activated or engaged.

Because the contractions occur in cycles, the intensity can be adjusted so the stimulation remains comfortable for the user.

People often enjoy EMS mode because it provides a different style of stimulation compared with the buzzing sensation of TENS. Instead of a surface tingling feeling, EMS creates a deeper sensation that involves the muscles themselves.

Many users simply explore different intensity levels and patterns to find the stimulation experience that feels most comfortable for them.

RUSSIAN MODE

Russian stimulation is another form of electrical muscle stimulation that uses a different waveform pattern compared with standard EMS.

This mode delivers stimulation in short rhythmic bursts, producing noticeable cycles of muscle tightening and release. Many users describe the sensation as feeling like stronger, more defined muscle contractions compared with regular EMS mode.

Because of the burst pattern used in Russian stimulation, the contractions can feel more pronounced. For that reason, many users prefer to use this mode for shorter sessions and adjust the intensity to a comfortable level.

Having both EMS and Russian modes available allows users to explore different stimulation patterns and choose the experience that feels best for their personal preference.

Please note: Russian mode produces stronger rhythmic muscle contractions than the other modes. Many users prefer to allow a day of rest between sessions for comfort. When exploring this mode, shorter sessions a few times per week may feel more comfortable due to the intensity of the stimulation.

EMS vs RUSSIAN MODE

Both modes stimulate the muscles through the electrode pads, but they create different contraction patterns.

EMS Mode

• Steady rhythmic muscle contractions
• Smoother contraction cycles
• Adjustable intensity levels

Russian Mode

• Short burst stimulation pattern
• Stronger contraction cycles
• Often used for shorter sessions
• Having multiple stimulation modes allows users to explore different patterns and customise their experience depending on what feels most comfortable.

Q. Is this rechargeable?
A. Yes! The device is rechargeable, so there’s no need to replace batteries. Simply connect the included USB charging cable when the battery level becomes low.

Q. Can the device be used by people with metal implants?

A. People with medical implants should always consult their healthcare professional before using any electrical stimulation device. Electrical stimulation devices should not be used by individuals with electronic implants such as pacemakers or similar implanted devices unless otherwise advised by a health care professional. Always read the instruction manual carefully and follow the safety guidance provided.

Q. Where should the electrode pads be placed?

A. Electrode pads should be placed directly on clean, dry skin. Many users position the pads along the length of a muscle group or on either side of the area where stimulation is desired. The instruction manual included with the device provides visual examples of common electrode placement options.

Q. What does the stimulation feel like?

A. Most users describe the stimulation as a gentle buzzing, tingling or pulsing sensation on the surface of the skin.

The intensity is fully adjustable, so you can start at a very low level and gradually increase it until the sensation feels comfortable for you. Different modes create slightly different sensations. For example, TENS mode often feels like a light buzzing or tapping sensation, while EMS and Russian modes may create rhythmic muscle contractions.

Everyone experiences electrical stimulation slightly differently, so it may take a few moments to find the setting that feels best for you.

Q. How strong should the intensity be?

Start at the lowest intensity and slowly increase the level until you feel a comfortable buzzing or muscle contraction sensation.The stimulation should feel noticeable but comfortable. If the sensation becomes uncomfortable, simply reduce the intensity using the device controls.

Q. Why can’t I feel the stimulation right away? 
If you cannot feel the stimulation immediately, try increasing the intensity slightly. Also check that:

• The electrode pads are firmly attached to clean, dry skin
• The lead wires are securely connected
• The pads are not worn out or lost their stickiness

Sometimes, a small adjustment in pad placement can also change how the stimulation feels.

Q. How long should a session last?

Session length can vary depending on personal preference and the area being stimulated. Many users explore sessions at different time lengths, adjust based on your comfort. Always follow the guidance provided in the instruction manual.

Q. Why are the electrode pads losing their stickiness? 
Electrode pads gradually lose their adhesion over time.

To help extend their life:

• Apply pads only to clean skin
• Return them to the plastic backing sheet after use
• Store them in a cool, dry place or back in the TENS hardcover carry case after use

Replacement pads are available HERE when needed.

Q. Can I use the device every day?

Many users choose to include electrical stimulation devices as part of their regular wellness routine. Always use the device according to the instructions in the manual and adjust the intensity and session length to a comfortable level.

Q. Can two areas be stimulated at the same time?

Yes. Because the device has dual output channels, two sets of electrode pads can be connected and used simultaneously if desired.

Q. Why does the stimulation sometimes feel stronger in certain areas?

Different areas of the body have different levels of sensitivity and muscle thickness. Because of this, the stimulation sensation may feel stronger or lighter depending on where the pads are placed. Simply adjust the intensity to a comfortable level for that area.

Q. Is it safe to use a TENS machine at home?

Portable electrical stimulation devices are designed to be simple to operate and suitable for home use when used according to the instructions provided. The device allows you to control the intensity level so you can adjust the stimulation to a comfortable setting. Many users start at a low intensity and gradually increase it until the sensation feels right for them.

As with any electrical device, it’s important to follow the guidance in the instruction manual and observe the recommended safety precautions.
