Setup

2. Attaching Electrode Pads

Ensure your skin is clean, dry, and free of lotions or oils before applying electrode pads. Peel the protective film from the medical-grade electrode pads. The pads are self-stick, pre-gelled, and latex-free, designed for stability and conductivity.

3. Connecting Lead Wires

Connect the lead wires to the electrode pads by inserting the pin connectors into the pad sockets. Then, plug the other end of the lead wires into the A/B Lead Connector ports on the top of the TENS unit (refer to Figure 2).

4. Electrode Pad Placement

Place the electrode pads firmly on the skin in the area where you wish to receive stimulation. Ensure pads are not overlapping. For optimal results, place pads on either side of the pain area, not directly over joints or bony prominences. Refer to the diagram below for common placement areas.

Operating Instructions

1. Powering On/Off

Press and hold the Power/Lock Button (refer to Figure 2) on the side of the device for a few seconds to turn the unit on or off.

2. Using the Touchscreen

The device features a 3.75-inch touchscreen for easy navigation. Tap the desired icons or areas on the screen to select modes, adjust intensity, or set the timer.

Figure 6: The RENPHO TENS Unit features a responsive touchscreen for intuitive control.

3. Selecting Modes

The unit offers 24 pre-programmed massage modes. Tap the 'Mode' area on the touchscreen to cycle through the available options. Each mode provides a different pulse pattern (e.g., Tapping, Acupuncture, Beat, Scrapping, Cupping, Tai Chi). All modes deliver pulse stimulation, not continuous output.

4. Adjusting Intensity

There are 20 strength levels available. Use the '+' and '-' buttons on the touchscreen or the Channel A/B Intensity Controllers on the side of the device (refer to Figure 2) to increase or decrease the intensity for each channel independently. Start with the lowest intensity and gradually increase until you feel a comfortable, yet effective, sensation.

5. Using Dual Channels

The RENPHO TENS unit features independent dual channels (A and B). This allows you to treat two different body areas simultaneously with different modes and intensity levels, or for two individuals to use the device at the same time.

Figure 8: Independent dual channels allow for simultaneous treatment of different body parts or by two users, each with their own mode and intensity settings.

6. Setting the Timer

The treatment duration can be set from 10 to 90 minutes. Tap the 'Timer' icon on the screen to adjust the time. The device will automatically shut off once the set time has elapsed.

7. Lock Function

To prevent accidental changes to settings during use, briefly press the Power/Lock Button (refer to Figure 2) to activate the lock function. Press it again to unlock the device.

Maintenance

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 turned off and disconnected from any power source before cleaning.

2. Caring for Electrode Pads

After each use, place the electrode pads back onto the provided pad holder or their protective film to maintain their adhesive quality. If pads lose their stickiness, gently wipe the adhesive surface with a damp cloth and allow to air dry. Replace pads when they no longer adhere well to the skin.

3. Storage

Store the device and accessories in the provided pouch in a cool, dry place, away from direct sunlight and extreme temperatures. Keep out of reach of children.

Troubleshooting

• Device not turning on: Ensure the device is fully charged. Press and hold the Power/Lock button for a few seconds.
• No sensation or weak sensation: Check that the electrode pads are firmly attached to the skin. Ensure lead wires are securely connected to both the pads and the device. Increase the intensity level gradually.
• Pads not sticking: Clean the skin area before application. If pads are old, they may need to be replaced. Gently clean the adhesive side of the pads with a damp cloth and air dry to restore some stickiness.
• Screen unresponsive: Ensure the device is not in lock mode. If it is, briefly press the Power/Lock button to unlock. If the issue persists, try restarting the device.
