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

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 chemical-
resistant 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’.

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 60601-1-1:20015,
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
MOBILE WORKSTATION WM-NP2 5
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.

2. Position the workstation on a flat surface and apply the brakes on two diagonally opposite
castors.
3. Remove the two cable ducts that are fitted on the rear of the intermediate shelf and the cable
tie that is fitted at the same height as the shelf. You can remove the cable tie by inserting a
flat bladed screwdriver behind the stud in the middle of the cable tie and pulling it towards
you, as shown in Figure 4.5.
4. Check that nothing has been placed on the shelf and, referring to Figure 4.6, loosen the two
M8 screws that are securing the shelf about half a turn using the supplied 6mm Allen key –
do not remove.

5. Take a firm hold of the shelf and, referring to Figure 4.6, unlock the two spring plungers fitted
on each side. Pull the spring plunger head towards you, twist 90° and release. The spring
plunger remains extended and is unlocked.
NOTE
The spring plungers cannot be removed from the shelves.
6. Move the shelf to the required height. Pull each spring plunger head, twist 90° and release.
The spring plunger head will spring back to its original position when aligned with the column
holes.
CAUTION
After moving the shelf, check that the four spring plunger heads are not
protruding. If any spring plunger head is protruding, the shelf may tilt
and get damaged due to insufficient engagement with the column holes.
7. Check that the shelf is not tilting and firmly tighten the two M8 screws with the Allen key.
