What to do if my TSI Instruments VELOCICALC 5725 has no display?

If your TSI Instruments Measuring Instruments has no display, there are several potential causes: the unit may not be turned on (switch it on); the batteries may be low or dead (replace batteries or plug in the AC adapter); or the battery contacts may be dirty (clean the battery contacts).
