4. Setup
4.1 Battery Installation
- Ensure the device is turned off.
- Open the battery compartment cover located on the back of the unit.
- Insert the 9V battery, ensuring the polarity (+/-) matches the diagram inside the compartment.
- Close the battery compartment cover securely.
4.2 Connecting Electrode Cables
- Insert the pin connectors of the electrode cables into the output jacks on the top of the TENS unit. There are two channels, each with two output jacks.
- Connect the other end of the electrode cables to the self-adhesive electrodes. Ensure a secure connection.
4.3 Attaching Electrodes to Skin
- Clean and dry the skin area where the electrodes will be placed. Avoid applying over broken or irritated skin.
- Remove the electrodes from their protective liner.
- Apply the electrodes firmly to the skin, ensuring good contact. Place electrodes at least one inch apart.
5. Operating Instructions
5.1 Powering On/Off
To turn the device on, rotate the intensity dials (one for each channel) clockwise from the 'OFF' position. To turn off, rotate the dials counter-clockwise until they click into the 'OFF' position.
5.2 Adjusting Intensity
Once the device is on, slowly turn the intensity dials clockwise to increase the stimulation level. Adjust to a comfortable, strong sensation without causing discomfort or pain. Each channel's intensity can be adjusted independently.
5.3 Selecting Modes
The TPN 200 Plus offers three selectable modes:
- Modulation (M): Varies pulse width and/or frequency to prevent nerve accommodation.
- Constant (C): Delivers continuous stimulation at a fixed pulse width and frequency.
- Burst (B): Delivers bursts of pulses at regular intervals.
Use the 'MODE' switch to select the desired treatment mode.
5.4 Adjusting Pulse Width and Pulse Rate
Use the 'PULSE WIDTH' dial to adjust the duration of each electrical pulse (range: 30 µs to 260 µs). Use the 'PULSE RATE' dial to adjust the number of pulses per second (frequency) (range: 2 Hz to 150 Hz).
General Guidance: For acute pain, a pulse rate of 80-120 Hz is often used. For muscle stimulation, 35-50 Hz. For chronic pain, 2-10 Hz. A pulse width between 175-200 µs is a common starting point. Consult a healthcare professional for specific recommendations.

6. Electrode Placement
Correct electrode placement is crucial for effective TENS therapy. Electrodes should be placed on clean, dry, intact skin around the painful area. Avoid placing electrodes directly over joints, bony prominences, or directly on the spine.
- For localized pain, place electrodes on either side of the pain site.
- For radiating pain, place electrodes along the nerve pathway.
- Ensure electrodes from the same channel are placed on the same side of the body or within the same pain region.
Refer to the electrode placement chart provided in your physical user manual for specific guidance on various body areas. If you are unsure, consult a healthcare professional.

7. Maintenance
7.1 Cleaning the Device
Wipe the TENS unit with a soft, damp cloth. Do not immerse the device in water or use abrasive cleaners. Ensure the device is completely dry before storage or next use.
7.2 Electrode Care
After each use, place the self-adhesive electrodes back onto their protective liners. If the electrodes lose their adhesiveness, they may be gently cleaned with a small amount of water and allowed to air dry. Replace electrodes when they no longer stick well or if they cause skin irritation.
7.3 Battery Replacement
Replace the 9V battery when the device's output weakens or fails to turn on. Follow the battery installation steps in Section 4.1.
7.4 Storage
Store the TENS unit and accessories in the provided soft carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
8. Troubleshooting
- No Sensation or Weak Sensation:
- Check if the device is turned on and the intensity dials are adjusted.
- Ensure the battery is correctly installed and not depleted. Replace if necessary.
- Verify that electrode cables are securely connected to both the unit and the electrodes.
- Ensure electrodes have good contact with clean, dry skin. Replace old or non-adhesive electrodes.
- Skin Irritation:
- Ensure skin is clean and dry before applying electrodes.
- Avoid over-tightening electrodes.
- Use fresh electrodes if they are old or dirty.
- Reduce intensity if sensation is too strong.
- Discontinue use and consult a healthcare professional if irritation persists.
