Chapter 5 Operation

5.1 Operation

WARNING

• 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.

• 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.

CAUTION

• Do not lean or stand on any part of the mobile workstation or accessory 

as failure of the product may result.

• Before commissioning an installation including a separation transformer, 

ensure its rating will not be exceeded by the equipment connected to it.

• 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.

• Never place any items on top of a monitor (if fitted) as these may topple 

when the mobile workstation is moved.

• The maximum storage load of each drawer is 5kg, otherwise stability 

may be compromised and this equipment may be damaged.

• Take care not to trap fingers when opening/closing or repositioning the 

drawer unit.
