5. Operating Instructions
5.1. Basic Operation
The MIO-CARE TENS device features a user-friendly digital keypad for easy navigation and control.
- Power On/Off: Press and hold the ON/OFF button located in the center of the keypad to turn the device on or off.
- Program Selection: Use the PRG+ and PRG- buttons to cycle through the 20 available medical TENS programs. The selected program number will be displayed on the screen.
- Intensity Adjustment: Once a program is selected, use the CH1 and CH2 arrow buttons (up/down) to adjust the intensity for each independent channel. Start with a low intensity and gradually increase until a comfortable, tingling sensation is felt.
- Monitoring: The graphic display provides real-time information on the active program and the remaining therapy time.
5.2. Electrode Placement
Correct electrode placement is crucial for effective and safe therapy. Refer to the dedicated Electrode Placement Manual included with your device for detailed diagrams and instructions for various body areas and conditions. General guidelines include:
- Clean and dry the skin area where electrodes will be placed.
- Place electrodes on healthy, intact skin, avoiding open wounds or irritated areas.
- Ensure electrodes are firmly adhered to the skin for good conductivity.
- Typically, electrodes are placed around or near the area of pain, ensuring the current passes through the affected region.
- Do not place electrodes over the heart, across the head, or on the front of the neck.
6. Maintenance
6.1. Cleaning the Device
Wipe the device with a soft, damp cloth. Do not use abrasive cleaners or immerse the device in water. Ensure the device is off and disconnected from the charger before cleaning.
6.2. Electrode Care and Storage
To prolong the life of your pre-gelled adhesive electrodes:
- After each use, reattach the electrodes to their protective plastic liner.
- Store electrodes in a cool, dry place, preferably in their original sealed bag.
- If electrodes lose their adhesiveness, they may need to be replaced. Do not use electrodes that are dry or damaged.
6.3. Battery Care
To maintain battery health, avoid completely draining the battery frequently. Recharge the battery when the low battery indicator appears. If storing the device for an extended period, ensure the battery is partially charged (around 50%) and recharge it every few months.
7. Troubleshooting
If you encounter issues with your MIO-CARE TENS device, refer to the following common troubleshooting steps:
- Device does not turn on: Ensure the battery is charged. Connect the charger and try again.
- No sensation or weak sensation: Check that electrodes are firmly attached to the skin. Increase the intensity gradually using the channel-specific arrow buttons. Ensure cables are securely connected to both the device and the electrodes. Electrodes may need replacement if they have lost their conductivity.
- Skin irritation: Discontinue use immediately. Ensure skin is clean and dry before application. Try repositioning electrodes. If irritation persists, consult a physician.
- Display issues: If the screen is blank or flickering, try turning the device off and on again. Ensure the battery is charged.
For persistent issues not resolved by these steps, please contact customer support.
