SAFETY INFORMATION

General Introduction

• Thank you very much for using our Nerve Muscle Stimulator. For you to use this device safely, please read this user manual carefully before your first use.
• Please keep this user manual with your device for future reference.
• This device is a portable electrotherapy device, featuring two therapeutic modes: Transcutaneous Electrical Nerve Stimulator (TENS) and Electrical Muscle Stimulation (EMS), which are used for pain relief and electrical muscle stimulation. The stimulator sends gentle electrical current to underlying nerves and muscle groups via electrodes applied on the skin. The parameters of the device are controlled by the buttons on the touchscreen panel. The intensity level is adjustable according to the needs of the individual user.

Medical Background

• EXPLANATION OF TENS
  Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive, drug- free method of controlling pain. TENS uses tiny electrical impulses sent through the skin to nerves to modify your pain perception. TENS does not work for everyone. However, in most patients it is effective in reducing or eliminating the pain, allowing for a return to normal activity.

• HOW TENS WORKS
  The TENS unit sends comfortable impulses through the skin that stimulate the nerve (or nerves) in the treatment area. In many cases, this stimulation will greatly reduce or eliminate the pain sensation the patient feels. Pain relief varies by individual patient, the mode selected for therapy, and the type of pain. In many patients, the reduction or elimination of pain lasts longer than the actual period of stimulation (sometimes as much as three to four times longer). In others, pain is only modified while stimulation actually occurs.

• EXPLANATION OF EMS
  Electrical Muscle Stimulation (EMS) is an internationally accepted and proven way of treating muscular injuries. It works by sending electronic pulses to the muscle needing treatment; this causes the muscle to exercise passively. This device has low frequency and in conjunction with the square wave pattern allows direct work on muscle groupings. This is widely used in hospitals and sports clinics for the treatment of muscular injuries and for the reeducation of paralyzed muscles, to prevent atrophy in affected muscles, and to improve muscle tone and blood circulation.
  HOW EMS WORKS
  The EMS units send comfortable impulses through the skin that stimulate the nerves in the treatment area. When the muscle receives this signal, it contracts as if the brain has sent the signal itself. As the signal strength increases, the muscle flexes as in physical exercise. When the pulse ceases, the muscle relaxes and this cycle is repeated until therapy is completed. The goal of electrical muscle stimulation is to achieve contractions or vibrations in the muscles. Normal muscular activity is controlled by the central and peripheral nervous systems, which transmit electrical signals to the muscles. EMS works similarly but uses an external source (the stimulator) with electrodes attached to the skin for transmitting electrical impulses into the body. The impulses stimulate the nerves to send signals to a specifically targeted muscle, which reacts by contracting, just as it does with normal muscular activity.

Indication for use (IFU)

• TENS:
  The device is designed to be used for temporary relief of pain associated with sore and aching muscles in the shoulder, waist, back, neck, upper extremities (arm), lower extremities (leg), abdomen and bottom due to strain from exercise or normal household work activities.

• EMS:
  The device is designed to be used to stimulate healthy muscles in order to improve or facilitate muscle performance:

How to Use the Device

1. Environmental operating conditions: Temperature: -5 ~ +40°C Humidity: Does not exceed 85% Atmospheric pressure range of 800 hPa to 1 060 hPa
2. Please make sure the device is on the OFF position when setting up the unit, adjusting the pads, or making a new connection.
3. Do not turn on the device before you place pads on your skin.

Before using the device, please check following carefully:

• Check the electrode wires for any damages or irregularities.
• Check the electrode pads for any damages or irregularities.
• Check for any physical damage on the unit..

1. Step 1: Connect the electrode to the device
   The FM-B2404 is equipped with two isolated channels A&B. This will allow you to set separate modes and separate intensities on each channel using the 2 outputs A, B. Before connecting the wires to the unit, decide which channel you wish to use (channel A or B). To use A channel only, connect the electrode wire(s) to outputs A. To use B channel only, connect the electrode wire(s) to outputs B. To use both A, B channels, connect the electrode wires to all outputs.

   • Plug the electrode wire into the output located at the bottom of the device.
   • Ensure that the electrode wires are fully inserted into the output and secured. Make sure the wires are not loose. A loose connection will lower the power output of your device, potentially causing unreliable connection.
   • Repeat 1 & 2 to connect another wire.
     CAUTION:
     Do not insert the plug of the patient lead wire into any AC power supply socket.

2. Step 2: Connect the electrode pads to the wires

   • Each wire has two leads with pin-in connectors. Insert the wire connectors into the pads. Make sure that at least one pair (2 pieces) of pads is attached to the same wire. One pad alone will not work.

   • Make sure at least one pair of pads is attached to the same wire.

   • Check the connections to ensure they are fastened.
     CAUTION:

   • Please make sure the device is on the OFF position when setting up the unit, adjusting the pads, or making a new connection.

   • DO NOT turn on the unit before you put pads on your skin.

   • Use at least one pair of pads. One pad alone will not work.

3. Step 3: Place Electrodes on Skin

   • Remove the plastic films on the pads.

   • Check if the adhesive side of on the pad is clean after removing the plastic film.

   • Place pads on the muscle you wish to treat. Make sure your skin has been cleaned of all dirt, oil, or lotions.

   • Be sure to place the adhesive side of pad on your skin.

   • We recommend keeping the plastic films for storing the pads after usage.

   • Make sure that you use at least one pair of pads on the same wire at the same time.

   • Make sure the pads are stick adhered closely on your skin.
     CAUTION:

   • Do not overlap pads or place one pad on top of another one.

   • Never remove the self-adhesive electrodes from the skin while the device is turned on. You will feel an uncomfortable electrical shock.|
     Electrode Placement The placement of electrodes can be one of the most important parameters in achieving success with this therapy. Of utmost importance is the willingness of the physician to try the various styles of electrode placement to find which method best fits the needs of the individual patient.
     Once an acceptable location has been achieved, mark down the electrode sites and the device settings, so the patient can easily continue treatment on them.

4. Step 4: Turn on the device

CLEANING AND CARE

Tips for Skin Care

Follow these suggestions to avoid skin irritation, especially if you have sensitive skin:

1. Wash the area of skin you will be placing the electrodes on with soap. Rinse thoroughly and dry the area completely before and after placing electrodes.
2. Excess hair may be clipped with scissors; do not shave stimulation area.
3. Many skin problems arise from the “pulling stress” from adhesive patches that are excessively stretched across the skin during application. To prevent this, apply electrodes from center outward; avoid stretching over the skin.
4. To minimize “pulling stress”, tape extra lengths of lead wires to the skin in a loop to prevent tugging on electrodes.
5. When removing electrodes, always remove by pulling in the direction of hair growth.
6. It may be helpful to rub skin lotion on electrode placement area during treatment down time when you are not wearing electrodes.
7. Never apply electrodes over irritated or broken skin.

Cleaning the Device

1. Remove the battery from the device before you clean the device.
2. Clean the device after use with a soft, slightly moistened cloth.
3. Do not use any chemical cleaners or abrasive agents for cleaning.

Electrodes

1. Use this device only with the leads and electrodes provided by the manufacturer.
2. Inspect your electrodes before every use. Replace electrodes as needed. Reusable electrodes can cause slight skin irritation, lose adhesion properties and deliver less stimulation if overused.
3. The ordering information of the electrodes pads: Available for purchasing on Amazon, or other e-commerce platforms. But it specifies the manufacturer of the electrode pads, the manufac-turer is the best choice for you. Be free to contact the seller if you need.
4. The electrode type: It is a kind of hydrogel and medical silicone.
5. The type of connector on the electrode: Pin-in.

Warning:

1. The electrode size, shape, and type may affect the safety and effectiveness of treatment and that a risk associated with use of the wrong size electrode is thermal burn.
2. We advises you to obtain replacement electrodes that are the same type, have the same dimensions and same connectors as those you distribute with your device.

TO REMOVE YOUR ELECTRODES:

1. Lift the corner of the electrode and gently remove it from the skin.
2. It may be helpful to improve repeated electrode application by spreading a few drops of cold water over the adhesive side and turn the surface up to air dry. Over saturation with water will reduce the adhesive properties.
3. Between uses, place the electrodes back onto the protective sleeve and insert them into the re-sealable bag and store in a cool dry place.
