As with any precision instrument, Gemscale 50 requires you to follow the Operating Instructions and to take the necessary care to get the most from your Gemscale.
  
    Calibration should be 
  checked when you move the scale from one surface to another when the scale is 
  ON. If necessary, re-calibrate the scale rather than TARE.
  
  
    The scale will not 
  operate when the battery needs to be replaced. 
  
    Avoid immersions and 
  spilt liquids.
  
  
    Avoid shocks, such as 
  dropping it on the floor.
  
  
    Prevent small 
  particles such as crumbs or stones from falling into the mechanism. Avoid 
  dust. 
  
  
    Avoid temperatures 
  over 145° F (60° C) such as a car dashboard in the summer sun. 
  
    Allow extreme 
  temperatures to settle before use, about 15 minutes. 
  
    Automatically 
  calibrate with a 50.000 carat weight only.
  
  
    The scale will not 
  give stable readings in excessively vibrative environments such as holding in 
  a hand or on a moving train. 
  
    Do not attempt to 
  dismantle the scale. Do not remove back label. This will void the warranty. 
  Follow the directions on the back for return and warranty covered repairs.
