General information This operating and user manual applies to the DuoCare 904 Laser by SYMBYX. This laser device is manufactured for SYMBYX Pty Ltd of Australia by Spectro Analytic Irradia AB of Sweden. Note: Irradia also manufacture an identical product called the MID-Lite Laser.
Separate power supply source (mains supply transformer) This device is specified to be connected only to the Lithium-Ion battery charger, Model 2241Li from Mascot. Essential performance and basic safety The device does not have an essential performance, the absence of which may result in an unacceptable risk. Basic safety is maintained when the device is stored, handled, and operated in normal condition, and in accordance with its normal use and intended use.
Device description and use This device is a transportable, hand-held and battery-operated medical laser product, with which the operator administers non-invasive transient class 3B infrared laser light to reduce pain and inflammation, as well as to promote tissue repair and recovery. This device is intended to be used as a supplementary treatment modality intended to be operated by a variety of practitioners, e.g., doctors, nurses, veterinaries, dentists, physiotherapists, dermatologists, chiropractors, and massage therapists.
Operation description of laser treatment (general) Treatment is performed by applying a generally optimal dose of laser energy onto and around a condition, using a point-by-point application procedure. An audible and visible signal informs the operator when to switch application point. At each signal, the laser aperture is moved ~ 1. 5 cm until the whole condition area has been covered.
Primary operating functions Use the key switch to put the device in operational mode (unlocking the device for use). The device enters a STAND-BY state. A yellow Light Emitting Diode (LED) is lit when the key switch is turned, indicating STAND-BY. Press and release the push-button to turn on the device (activate device).
Failure of charger, battery or the connector. Contact service for support. If the Light Emitting Diode on the charger is not lit – neither green nor orange – then the charger is not functioning as intended. Contact SYMBYX customer service for support via info@symbyxbiome.com.
Treatment controls The treatment controls are indicated by the following symbols: When a control button is pressed, the device sets automatically the parameters required for delivering a generally optimal dose per application point onto and around a condition. When pressed, the Light Emitting Diode (LED) next to the control button is lit and the output power (in mW) and dose (in Joules) are shown on the LCD display.
Overview chart of the treatment controls The treatment controls overlap each other. There is no risk of harm using one control instead of another. The operator is advised to use the control they find most suitable or which corresponds best to the condition being treated. The following controls are guidelines only.

IMPORTANT! New patients using laser treatment for the first time should commence at a lower dose and/or treatment time to evaluate reaction. For some patients suffering complex pain conditions, the laser treatment may cause in rare cases a transient increased pain. SYMBYX recommends a maximum of 30...
Treatment examples The apertures of the device cover a surface area of 4-5 cm², and are moved approximately 1.5-2 cm at each signal. A treatment area of 10 cm² is covered after 1-2 signals. The examples in the chart below are general guidelines based on patients with normal height and body fat, and with skin phototype I-III.
Treatment adjustments Skin phototype, hair colors Skin pigmentation varies with the amount of melanin in the skin and is assessed on a scale from I-VI. The skin phototype is determined by complexion (white, brown or black skin) and the result of exposure to ultraviolet radiation (tanning). In connection with laser treatments, darker brown and black skin and hair are more easily burned due to the absorption of light in melanin.
Body constitution The patient’s body constitution may influence the dose of laser energy needed to achieve the most efficient results. In the chart below, general guidelines are described for adjusting the treatment. This chart only applies when treating conditions or disorders that are not superficially or externally situated, such as wounds.

used as a MOP (Means of Protection). By using a specified non-standard connector, the risk of connecting the device to the wrong charger is greatly reduced. The connector selected can be connected in only one way, reducing the risk of reversed polarity. The charger used is in compliance with IEC60601-1.
Battery safety Removal of the battery should only be performed by trained service personnel. The operator must not use the device if deformed or damaged, dropped in water, producing excessive heat, or smells strangely. In these cases, the operator should contact the supplier or the manufacturer for technical service or replacement of parts.
▪ Do not disassemble the Lithium-ion batteries. Doing so can damage the protection circuit or protective safeguards, which may cause an internal or external short circuit. It may also cause battery fluid leakage, heat generation, explosion or fire. ▪ Do not strike or throw the device containing the lithium-ion battery or the battery housing. The impact may cause battery fluid leakage, explosion or fire.
Replacement of battery Ensure that the key switch has been removed and that the device is turned off (e.g., no LED indicators are lit). Remove the two screws by using a matching screw driver. Pull out the battery housing from the laser head. The screws used are M2.5 countersunk.
Transport and storage of the battery housing Ensure that the push-button (ON/OFF) and the key switch are turned off and that the key has been removed. Do not carry or store a disconnected battery housing together with metal necklaces, hairpins, or other electrically conductive materials. This may short circuit the battery, which could result in excessive current flow and possibly battery fluid leakage, heat generation, explosion or fire.
Laser safety General laser safety information These instructions for use are intended to minimize hazardous situations and the risk of harm due to laser radiation of Class 3B. They include such things as: Safe handling and use of the device Safe storage and transportation of the device NOHD distance Use and descriptions of correct protective eyewear (i.e., wavelength range and optical density OD+)
The device is equipped with a stand-by/ready function. The device enters stand-by when the key switch is turned to the “ON” position. In the “ON” position, the yellow LED next to the key switched is activated.

Important notes regarding periodic measurements of the output power: The power meter must be able to: measure the wavelengths that the laser emits measure output powers of at least 1000 mW (or 1 W) In addition, the following routines should be adhered to: Ensuring that the aperture lenses are clean before measuring the output power (dirty lenses may reduce the output power by absorption and cause discomfort due to the heat generated) The power meter should be placed in contact with, or very close to, the laser aperture to ensure that the whole beam is fitted onto the...
Protective eyewear. Personal protective equipment Optical density should be minimum +3 (OD+3), which means that 1/1000 of the light passes through the protective eyewear. The power of a 0.5 W laser is reduced to 0.5 mW by using protective eyewear with OD+3. Through the proper use of protective eyewear by both patients and operators, the possibility of eye injuries caused by laser radiation is reduced to a minimum.
Visual inspections 10.2 The operator should perform a visual inspection of the device before use and contact the supplier or manufacturer for support or service in any case where real or perceived changes in the performance of the device occur. To ensure a safe inspection, follow the instructions below: Inspection Potential problem Action to be taken...
