Operating Instructions

1. Powering On and Initial Settings:

1. Ensure electrodes are properly placed on your skin.

3. The device will default to a standard mode.

2. Selecting a Mode:

Press the MODE button to cycle through the available treatment modes:

• Constant Mode: Delivers continuous stimulation.
• Modulation Mode: Varies the pulse width and/or frequency to prevent nerve accommodation.
• Burst Mode: Delivers short bursts of high-frequency stimulation.
• SD1/SD2 Anti-Accommodation Modes: Specialized modes designed to prevent the body from adapting to the stimulation.

3. Adjusting Intensity:

Slowly turn the intensity dials (CH1 and CH2) clockwise to increase the stimulation intensity. You should feel a comfortable tingling sensation. Do not increase the intensity to a level that causes pain or discomfort. Each channel can be adjusted independently.

4. Adjusting Frequency and Pulse Width:

After selecting a mode, you can adjust the frequency (Hz) and pulse width (µs) using the incremental control buttons (▲ and ▼) and the SET button. Refer to the Patient Guide for recommended settings for specific conditions.

5. Treatment Duration:

The device may have a default treatment duration. You can typically adjust this using the incremental control buttons after pressing the SET button. Consult your healthcare professional for recommended treatment times.

6. Turning Off:

To turn off the device, slowly turn both intensity dials (CH1 and CH2) counter-clockwise until they click into the 'OFF' position. Remove electrodes from your skin.

Electrode Placement Guide

Proper electrode placement is crucial for effective pain relief. The electrodes should be placed on clean, dry skin, typically around or near the painful area. Avoid placing them directly over joints or bony prominences where they may not adhere well.

For detailed placement instructions for various body parts and conditions, please refer to the included Patient Guide to TENS. Below are general examples:

Image: Examples of electrode placement for pain relief.

• Back Pain: Place electrodes on either side of the spine, or directly on the painful area.
• Shoulder Pain: Place electrodes around the painful area of the shoulder, avoiding the neck.
• Leg/Knee Pain: Place electrodes above and below the knee, or on either side of the painful area on the leg.
• Always ensure electrodes are at least 1 inch apart.

Maintenance and Care

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 completely dry before storage or next use.

Electrode Care:

• After each use, reattach the electrodes to their protective liner to preserve their adhesive quality.
• Store electrodes in a cool, dry place.
• Replace electrodes when they lose their stickiness or if they cause skin irritation.

Battery Replacement:

• When the battery indicator on the LCD screen shows low power, replace the 9V PP3 battery as described in the "Setup" section.
• Dispose of used batteries according to local regulations.
