CAE Simulator Instructor panel
 

I am about to instruct on an Airbus 320 CAE simulator. To date I have mostly used Thales and the instructor panel is straight forward to use.

I have been given a CD to get familiar with the panel. Whenever I enter the ZFW or GW or Fuel (Metric and in any format!) it keeps giving out of bounds. If for example it want to enter a ZFW of 42,500 kgs I am trying to enter it 42500, 42.5, 42.500. Nothing works. I am not sure whether its a CD problem or I am doing something wrong.

Any help would be greatly appreciated.
