3. Safety Precautions
WARNING
Before using your scale, please ensure you have read and understood the contents of this
manual. It contains important information and guidance for installation, safe use and general
maintenance of the device.
The manufacturer shall not be liable for damages arising out of failure to comply with the
following instructions:
• When using electrical components in safety critical environments, always conform to the
relevant regulations.
• Incorrect installation or use other than in accordance with the instructions provided within this
manual will render the warranty null and void.
• This device is designed for indoor use only.
• Ensure the scale is used within the specified operating temperature range.
• The scale meets requirements for electromagnetic compatibility.
• Ensure that the patient does not lean against the device due to a risk of falling.
• Following assembly to an Oxford patient lift, the scale must not be rotated horizontally.
Rotation is only permitted in connection with 360° swivel bearings installed on the lift.
• The device must not be modified from its standard configuration. Unapproved modifications
may result in injury and/or death to the patient and/or carer and will render all liability and
warranty invalid.
• Cardon joints are assembled with the loadcell by the manufacturer. Manually twisting or
adjusting cardon joints can cause instability and may result in injury and/or death to patient
and/or carer.
WARNING
• DO NOT exceed the maximum safe working load of the scale which is stated on the front panel
and on the label on the reverse side of the scale. The scale will emit audible ‘beeps’ when
loading exceeds the maximum rated capacity.
• NEVER exceed the safe working load of the lift that the scale is fitted to.
NOTE: If you require additional assistance with the set-up or use of your scale, please contact your
local authorised dealer or Joerns Healthcare direct.
