Program 1: Strength/Firming
This program exercises targeted muscle fibers at a high power working level. It includes a warm-up and workout period. The stimulation is continuous at a subtetanic (twitch) frequency during the warm-up period. At the workout phase, the stimulation alternates between weak twitch contractions and stronger tetanic contractions.
This program is perfect for use on your abdominal muscles if you want to strengthen your core. Using this program on your quadriceps and legs will help you get toned/muscular legs.

Program 2: Endurance

The Endurance Program exercises muscle fibers at an average-medium working level, and is meant to work slow twitch muscle fibers. It is designed to increase the above average intensity of muscle strength or effort that must be maintained over a long period of time.

This program is ideal for athletes who are involved in endurance sports that require more slow-twitch muscle fibers such as long distance running, cross country skiing, soccer, etc.

Program 3: Resistance

This program works by using a combination of fast twitch and slow twitch muscle fibers and is intended to increase muscle toning and basic strength. It aims to increase the time the muscle is able to maintain a high-power working point. Your muscles become stronger when you do resistance training. Therefore, it is recommended to use this program repeatedly throughout the week to exhaust the muscle.

Use this program in areas where you wish to develop increased muscle mass.

Program 4: TENS

The TENS active rehabilitation program is for the relief of chronic pain, muscle injury, pinched nerve and other muscle disorders. It produces muscle twitches at a very low frequency. These twitches act like a massage and can be used after your workout.

Program 5: TAMEXX® Wave Active Recovery

Most professional, amateur, and elite athletes all over the world use TAMEXX® Wave Active Recovery Program to recover quickly from injury or surgery. This program helps to mitigate and eliminate muscle disuse atrophy due to neuromuscular disease, muscle-skeletal disorder, chronic pain and other injuries – especially sports-related and auto accidents.
The TAMEXX® Recovery Wave system is fantastic for recovery from sports competition or practice. This program helps to clear lactic acid and increase blood flow at lower frequencies. It is really good for muscles that are tired after vigorous workouts.

Program 6: Russian Stimulation (Muscle Building)

Russian Stimulation was developed in order to help train world-class athletes and body builders. Russian Muscle Stimulation is very similar to EMS but with a higher frequency of 2,500HZ at 50 pulses per second. This allows for deeper, stronger, yet comfortable penetration to the muscle.

It is recommended for the experienced user of electronic muscle stimulation, and is popular among athletes, body builders, and individuals who want to gain muscle mass.

Program 7: TAMEXX® Micro-Current

Micro Current Therapy is the application of very low levels of electrical stimulation to muscles, ligaments, and joints to provide pain relief and promote tissue healing. Micro Current Therapy is the only electrical therapy whose currents can penetrate cells. All other currents such as TENS and Acupuncture pass over the cells. Our proprietary TAMEXX® Micro-current program can also be used in areas that have cellulite and wrinkles such as the hamstrings, buttocks, and arms. 

Program 8: TAMEXX® Interferential Current (IFC)

IFC allows for a higher intensity and deeper penetration to the muscle at a more comfortable level. Through the use of its greater frequency, a higher HZ is used, thus increasing the depth of penetration (less skin resistance). The slightly different proprietary TAMEXX® IFC currents are superimposed to form what is called interference, which blocks the transmission of pain messages to the brain, resulting in much needed relief for users.

Interferential therapy is used primarily for treating muscle injuries.

Follow the simple directions below and you will be on your way to pain relief and muscular strength:


This step is very important. The machine runs on a rechargeable battery only and will not turn on unless the battery is inside the machine.


Unwind the wires and insert them into each output channel / port located at the base of the unit.


Each wire will have a total of 2 pads.


Place the electrodes on the skin over the area you want to treat. If you are unsure about where to place the pads, visit our Pad Placement Charts for EMS & TENS


Turn the unit on by pressing down on the power switch that is located on the right side of the machine.


Choose from 8 different Pre-Set programs based on whether you want to focus on muscle building, toning, pain relief, recovery etc.


Set the automatic timer from 15, 30, 45, or 60 minutes. After you select the appropriate treatment time, press the orange START button.


SLOWLY increase the intensity for each channel and stop at a level that is most comfortable for you. Press the '+' button to increase the intensity, and the '-' button to decrease it.

Works tremendously

After 6 months to a year of usage, I can honestly say it works well! The reason why I purchased this machine is because I needed something to work my weaker muscle one at a time rather than compound movement since it doesn’t work as well as I wanted. This Tamtec Sport 4+ does the job and has all the required settings, what I love the most is using P4, P7 and P8 to relax the muscles after strenuous workout. Can’t go wrong with it! Definitely get the wrap to hold the pads because after few uses, the pads lose stickiness after a while. I’d suggest Toneamatic find a way to make the stickiness a lot stronger after 15~25 uses.

Highly recommend this product

I purchased a Home-Slim Tone-A-Matic model TMS6000, over 25 yrs ago and the only problem I’ve had over the yrs is one of my wires became defective 3 weeks ago. My main reason for purchasing this device was because of a leg injury I suffered back then, it helped me regain my muscle strength. Since then, I've used this device on a regular basis for knee surgery, it helped me with back pain and lately both hip surgeries eight yrs apart. For those of you who remember those devices, they came with elastic bands to hold the pads and today they come with self adhesive pads which is great. I was very grateful and relieved to find that the company is still in business and provides parts for old models, what a relief. The customer service rep Annia was very pleasant and helpful. In my experience I strongly recommend these devices.

I do appreciate the soon shipping. The product comes in a nice bag where all the parts are safely in. The machine has all the instructions and I am already on the way to try it, I think is going to fill all expectations because the company is responsible and caring.

Works very well

Simple to use. Could use more details on pad placement. The pictures in the instruction book are good but more option would be better. The sticky pads only work 6 - 8 times. Need to get the belt or more stickum.
