iSTIM EV-804 TENS/EMS Combined Unit User Manual

Introduction

The iSTIM EV-804 is a versatile TENS (Transcutaneous Electrical Nerve Stimulation) and EMS (Electrical Muscle Stimulation) combined unit designed for pain relief and muscle stimulation. This device offers a non-invasive, drug-free method to manage various types of pain and assist in muscle recovery and strengthening. It features 2 channels, 5 TENS modes, and 2 EMS modes, providing a comprehensive solution for personal therapeutic needs.

Safety Information

Please read all instructions and safety warnings carefully before using the iSTIM EV-804 unit. Failure to do so may result in injury or device malfunction.

• Do not use if you have a pacemaker, implanted defibrillator, or other metallic or electronic implanted devices.
• Do not use on open wounds, broken skin, or over cancerous lesions.
• Consult a physician before use if you are pregnant, have epilepsy, heart disease, or any other serious medical condition.
• Keep out of reach of children.
• Do not use while driving or operating heavy machinery.
• Do not apply electrodes to the head, across the chest, or over the carotid sinus nerves (front of the neck).
• Only use electrodes and accessories supplied or recommended by iSTIM.
• Do not use additional electrode gel. The Japanese SEKISUI gel on the electrodes is sufficient.

Setup

Follow these steps to set up your iSTIM EV-804 unit for first use:

1. Insert Battery: Open the battery compartment on the back of the unit and insert the provided 9V battery, ensuring correct polarity. Close the compartment securely.
2. Connect Lead Wires: Plug the lead wires into the output jacks at the top of the iSTIM EV-804 unit. There are two channels (CH1 and CH2).
3. Attach Electrodes: Connect the pin connectors of the lead wires to the adhesive electrodes. Ensure a secure connection.
4. Prepare Skin: Clean and dry the skin area where electrodes will be placed. Remove any lotions, oils, or dirt to ensure optimal adhesion and conductivity.
5. Apply Electrodes: Carefully peel the electrodes from their protective liner and apply them firmly to the desired treatment area on your skin. Refer to the Electrode Placement Guide for recommended positions.

Operating Instructions

The iSTIM EV-804 offers both TENS and EMS functionalities with various modes and adjustable settings.

Device Overview and Controls

This diagram illustrates the main controls of the iSTIM EV-804 unit. Key controls include:

• CH1 & CH2 Power Intensity Control: Rotary dials on top for adjusting stimulation intensity for each channel.
• Increase or Decrease Setting Value: Up (▲) and Down (▼) arrow buttons to adjust parameters.
• MODE Button: Cycles through available TENS and EMS modes.
• SET Button: Used to select and confirm settings for Pulse Width/Rate and Treatment Time.

Power On/Off

To turn the unit on, slowly rotate either the CH1 or CH2 intensity dial clockwise until you hear a click and the display illuminates. To turn off, rotate both intensity dials counter-clockwise until they click off.

Selecting TENS or EMS Mode

The iSTIM EV-804 offers 7 modes in total: 5 TENS modes and 2 EMS modes. Use the MODE button to cycle through the available programs. The display will indicate whether TENS or EMS mode is active, along with the specific program number.

This image highlights the key features of the iSTIM EV-804, including its 7 modes (5 TENS, 2 EMS) and 24 programs, 2 independent channels for multiple massage areas, TENS+EMS combo functionality, and adjustable settings for pulse rate, pulse width, intensity, and treatment time.

Adjusting Parameters

After selecting a mode, you can adjust specific parameters:

• Pulse Rate (Frequency): Press the SET button to highlight the pulse rate. Use the Up/Down arrows to adjust the frequency (Hz).
• Pulse Width: Press the SET button again to highlight the pulse width. Use the Up/Down arrows to adjust the pulse width (µs).
• Treatment Time: Press the SET button a third time to highlight the treatment time. Use the Up/Down arrows to set the desired duration (minutes).
• Intensity: Once parameters are set, slowly increase the intensity for each channel using the respective rotary dials (CH1 and CH2) until you feel a comfortable, strong sensation. Do not increase to an uncomfortable level.

Electrode Placement

Proper electrode placement is crucial for effective treatment. Refer to the included Electrode Placement Guide for specific recommendations for different body parts and conditions. General guidelines include:

• Place electrodes on clean, dry, intact skin.
• Ensure electrodes are at least one inch apart.
• For TENS, place electrodes around or near the painful area.
• For EMS, place electrodes over the muscle belly you wish to stimulate.
• Avoid placing electrodes directly over joints, bony prominences, or areas with reduced sensation.

This image provides visual examples of TENS and EMS applications for various body areas, including the neck, back, legs, and abdomen, demonstrating how the unit can be used for drug-free pain relief and muscle training/toning.

Maintenance

Proper maintenance ensures the longevity and effectiveness of your iSTIM EV-804 unit and electrodes.

• Cleaning the Unit: Wipe the unit with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.
• Electrode Care:
  • After each use, place the electrodes back on their protective plastic liner.
  • Store electrodes in a sealed bag to prevent drying out.
  • If electrodes lose their stickiness, gently wipe the adhesive surface with a damp cloth and let air dry. Do not use soap or alcohol.
  • Replace electrodes when they no longer adhere well to the skin or if the sensation becomes uneven. The provided electrodes are designed for up to 15 uses.
• Storage: Store the unit and accessories in the provided paper case in a cool, dry place, away from direct sunlight and extreme temperatures.
• Battery: Remove the battery if the unit will not be used for an extended period to prevent leakage.
