MOBILE WORKSTATION WM-NP2

Important Information - Please Read Before Use

Important Information - Please Read Before Use Intended use The Olympus WM-NP2 mobile workstation is intended for use in medical facilities under the direction of a trained physician, and has been designed to be used with a range of Olympus equipment to facilitate GI endoscopy, endoscopic ultrasound, respiratory and surgical endoscopic procedures. Do not use the equipment for any purpose other than its intended application. The safety and performance of an endoscopic system depends not only on the endoscope but also on the ancillary equipment used with it. Ensure any ancillary equipment is compatible with the endoscope and other equipment used.

Instruction manual Please read this manual carefully before attempting to use the Olympus WM-NP2 mobile workstation as it contains important information on the proper care, handling and use of the equipment. In addition, read the manuals of any other units (light source, endoscope, etc.) that form part of the system. If you have any questions or comments regarding the information in this manual, please contact Olympus. These instructions should be retained for reference during the life of the product.

Signal words The following signal words are used throughout this manual: WARNING

Important Information - Please Read Before Use

Handling precautions Follow the warnings and cautions given below when handling this workstation. This information is to be supplemented by the warnings and cautions given in each chapter. WARNING

• The WM-NP2 mobile workstation should only be used in a medical facility under the direction of a trained physician. • Explosion hazard - never install or use the WM-NP2 mobile workstation within the zone of risk of flammable gases. The workstation is fitted with antistatic castors, none of the medical electrical equipment with which the workstation is intended to be used is ‘AP’ or ‘APG’ rated, therefore never install or use the WM-NP2 mobile workstation within the zone of risk of flammable gases. • To prevent patient shock, the combination of equipment used on the WM-NP2 mobile workstation should never be applied directly to the heart. • After wiping with a piece of moistened gauze, dry the workstation and mounted devices thoroughly before using it again. If it is used while still wet, there is the risk of an electric shock. • Use personal protective equipment to guard against dangerous chemicals and potentially infectious material, otherwise, blood, mucus and other potentially infectious material from the patient could pose an infection risk. During cleaning, wear appropriate protective equipment, such as eye wear, face mask, moisture-resistant clothing and chemicalresistant gloves that fit properly and are long enough so that your skin is not exposed. • To prevent user or patient cross-contamination, do not hang contaminated endoscopes on the scope hanger. • The WM-NP2 should be used in accordance with the following. Otherwise, the workstation will be ‘top heavy’ and may lose stability and topple, causing equipment damage and/or personal injury.  Do not attach more than one LCD monitor arm to each side

of the workstation.  LCD monitor arms and monitors should not be installed and used on an empty workstation.  LCD monitor arms and monitors should be installed after all other equipment is installed on an appropriate place on the workstation. • (USA only): The power cord on this unit is fitted with a ‘hospital grade’ plug. Grounding reliability can only be achieved when this equipment is connected to an equivalent receptacle marked ‘hospital grade’.

MOBILE WORKSTATION WM-NP2

Important Information - Please Read Before Use

WARNING

• (RoW only): The power cable on this unit is terminated in flying leads, for a suitable plug to be fitted according to the area of intended use. The cores of the cable are coloured in accordance with the following code: BROWN LIVE (‘HOT’) BLUE NEUTRAL GREEN/YELLOW EARTH (GROUND) Only suitably qualified personnel should fit the power plug to this cable.

CAUTION

• Do not exceed the load capacity detailed in Chapter 7. • Do not lean or stand on any part of the mobile workstation or accessory as failure of the product may result. • When assembling equipment onto the mobile workstation, the installation should meet the requirements of EN IEC 60601-1-1:2001, the safety standard for medical electrical systems. • Before commissioning an installation including a separation transformer, ensure its rating will not be exceeded by the equipment connected to it. • When configuring a system, the user should ensure that there is sufficient spare equipment available that in the event of a fault in any part of the system, the endoscopy procedure may be completed or terminated without endangering the patient. • When installing the mobile workstation in the procedure or operating room, ensure that the mains cable has sufficient slack that it cannot be pulled taut as the mobile workstation is moved around the working area. If necessary, relocate the mains connector to a nearer supply socket. • Section 5.2 Manoeuvring gives detailed instructions and precautions which must be read and understood before attempting to move the mobile workstation. • Spray type medical agents, such as lubricants, anaesthetic or alcohol, should be used away from the mobile workstation. • Keep open containers of liquid away from electrical equipment used on the mobile workstation to prevent operator electrical shock and equipment damage. Do not use the system if liquid has entered the equipment. • To minimise risk of injury, it is recommended that heavy items are placed on the mobile workstation by two people working together. Ensure electrical items used on the mobile workstation are positioned centrally on the shelves. • Never place any items on top of a monitor (if fitted) as these may topple when the mobile workstation is moved. • The electrical resistance of the conductive antistatic castors should be tested at regular intervals in accordance with ISO 2878 to assess antistatic effectiveness. • Avoid contact of the castor wheels with oil and avoid a build up of floor cleaning wax and polish as these will impair the antistatic effectiveness of the castors.

Important Information - Please Read Before Use

CAUTION

• Store and use the WM-NP2 mobile workstation within the environmental conditions described in Chapter 7; failure to do so may lead to equipment malfunction or failure. • Before attempting to move the workstation outside the procedure room, ensure that the endoscope and fluid containers are removed. • There are no operator-serviceable components on the WM-NP2 mobile workstation. Refer servicing to qualified service personnel. • Before commencing shelf adjustment, ensure equipment is disconnected and removed from the shelf. • To minimise the risk of injury and/or damage, do not fit accessories other than those described in Section 1.1 to the WM-NP2 mobile workstation. • The maximum storage load of each drawer is 5kg, otherwise stability may be compromised. • Ensure each drawer is locked when moving the workstation. • Take care not to trap fingers when opening/closing or repositioning the drawer unit. • When installing a keyboard on the keyboard tray, ensure the cable passes around the outside of the sliding runner, otherwise the cable may be pinched when operating the sliding tray. • Check all equipment connectors on a regular basis to ensure there are no loose connections.
