I'm used to the DVM (DVM-7400). Where is the 'Test Button' on the DVMHD? (Model DVM-8400/8500)

Since the DVM8400 and DVM8500 has an LCD menu interface, they do not have the traditional test button that is found on many of our other products.  However, you can easily access the test feature by pressing the knob 3 times.  This selects the menu option 'Main Menu-->Play Menu-->Play Test File'. This will cause the lowest numbered clip on the flash card to start playing.
