How to use


HiDow markets pain management solutions that include a Class II medical device that is approved and licensed by the US Food and Drug Administration, SA Department of Health, and Conformité Européenne. Side effects entailed to a TENS unit are very rare; however, our devices cannot be used by any individual impacted by the following medical conditions.

How to use TENS and EMSPacemaker and Severe Heart Disorders
It is possible that TENS therapy can interfere with an implanted medical device. You should avoid any TENS unit if you have a pacemaker or heart disease. Electrical currents generated from TENS units can interfere with the functionality of the pacemaker which can possibly ruin the implanted device and can put yourself at risk.

While some pacemakers are made safe with TENS therapy, it’s best to speak to a healthcare professional before trying the device.

If you’re pregnant, or think you’re going to get pregnant, you should avoid using a TENS unit. To be clear, pregnant women are not at risk when opting for electrotherapy. But the effects of TENS therapy to an unborn child can pose risks which is why you should avoid it.

You may use electrotherapy under the supervision of your practitioner. However, even with this intention, you should avoid it during the first and second trimester. Also, never place the electrodes above the uterus.

Epilepsy and Seizures
While the research is still inconclusive, there is a possibility that electrical currents can trigger epileptic episodes and seizures. Some medical professionals warn to avoid it while others suggest to practice caution.

For safety reasons, do not use them to avoid any episodes.

TENS therapy influences the circulatory system which can causes issues within the lymphatic system and can cause additional fluid retention. Because lymphedema compromises the skin’s integrity and causes swelling, it is advisable to only use TENS units on healthy skin.

Cochlear Implant
Electrical currents from TENS devices can adjust the frequency of your cochlear implants resulting for a re-tune. Simply put, this can alter the cochlear implant’s maps. A medical professional will have to reprogram them leaving you deaf for the time-being.

Side-effects to TENS therapy is rare, but if you have any conditions mentioned above, you should not use electrotherapy devices. You should also avoid it if you have the following:

  • Deep vein thrombosis (DVT)
  • Cancer or are recovering from cancer
  • Any electronic implanted device
  • Plates in your body and/or titanium screws and/or pins

Important: Never place gel pads or accessories directly on your heart or the temple region on either side of your head. If you are unsure, please, consult with your doctor before using our device.

  • The device battery is built into our HiDow devices and is non-removable.

HiDow Maintenance and Care

  • Make sure your skin is free from any dirt, oil, or lotions.
  • Before applying the gel pads, put a few drops of water on your fingers and rub them on both pads. This will help the gel pads maintain their adhesiveness.
  • When you finish using the device, turn it off.
  • Take off the gel pads.
  • Place the protective films back on the gel pads or place them on the pad holder.
  • Take the electrode wires out from the device and place back in the box until next use.
  • Store your HiDow device in a cool, dry place until next use.


Explanation of HiDow Modes

How to use HiDow Tens UnitMode 1- Kneading: Simulates the thumbs fingers and palms of a real massage therapist. The
sensation should feel like a vibration. Focuses in on hypertension and stress and helps to break
that down returning full range of motion and flexibility.

How to use TENS ElectrodesMode 2- Acupressure: a much more rapid and focused pulse that focuses in on any knot or adhesion in the body. It puts enough pressure on it to break it down and release any acidic (lactic) content within.

Where to put TENS electrode padsMode 3- Tapping: simulates a second heart beat. By tapping the muscle you increase the body’s
natural blood flow and oxygen supply to target area. This also helps flush any inflammation or swelling in target area.

TENS Electrode placementMode 4- Hot Stone: relaxation mode. This simulates a regular manual rolling massage helping the soft tissue to release and relax.

How to place TENS Electrode padsMode 5- Cupping: This will reach in, grab, and stretch the muscle. Help to lengthen and broaden
it, the release it as it sets it back. This will help to increase flexibility and mobility of the muscle.

How to use HiDow EMS ACU XPDMode 6- Shuffle: This is a combination of modes 1,4,5. This is a great mode to use when cooling
down from an exercise.

How to Operate my TENS UnitMode 7- Elbow Pressing: This mode simulates the massage therapist by pressing on the body with the elbow. It is designed to relieve muscular spasm pains on the shoulder and back.

Where to place my EMS ElectrodesMode 8- Trigger Point: This is simulating a massage therapist by pressing the trigger points along meridians with finger tips. It is used to relieve fatigue, keep healthy and energetic, and to relax tendons.

How to set HiDow ACU XPD-SMode 9- Reflexology: This mode has been designed for the shoes. It simulates a reflexology session through the socks and/or shoes using several different stimulation patterns.

Different Modes on HiDow TENSMode 10- Auricular Therapy: This mode is also known as “alpha stim” or “micro current”. When used properly you should use the earflap attachment. It works 2 ways. By simulating an alpha wave in the brain it has been known to help sleep patterns, behavior, and endorphin release. Also, it will relax the sub occipital muscles and vaso dilate, helping with migraines and headaches.

Different Modes on HiDow EMSMode 11 & 12 Micro Current (A) / Micro Current (B): These two modes are similar but different in frequency. Micro Current is well known as “human bioelectricity”. This mode is to prevent and treat diseases by using the current to increase micro circulation to the area. This can help with swelling, joint relief, muscle pain relief, and performance.

Mode 13: Muscular Warm Up: This mode is designed to increase the temperature of muscle ligaments and joints. It can extend the range and ability of joints and ligaments, also can reduce muscle viscosity and improve muscular contraction and flexibility. Muscular warm up is a key to improve quality of training and prevent injury of sports.

Mode 14: Muscular Reinforcement: This mode can improve quality of training, help to prevent sports injuries, and strengthen muscle. It can also be used to provide a suitable physical exercise which can accelerate the blood circulation of injured or atrophic muscle tissues and promote the protein synthesis so as to accelerate the rehabilitation of muscular atrophy.

Mode 15: Muscular Relaxation: This mode is designed to stimulate muscles, release tension and promote overall well being through simulating an all embracing massage.

Mode 16: Contract and Hold: This mode is the longest contraction on the machine. It is designed to simulate a flex movement to help build muscle tissue.

Mode 17: Ramping wave: This mode is designed to start out with number 3, tapping. It will get faster and deeper into the belly of the muscle as it continues until it goes to a fully facilitated contraction. Then it will allow the muscle to release. This has been used to increase endurance and build fatigue resistance.

Mode 18: Tapping and kneading: a mixture of the fast and slow contractions.
