How do I clear my memory using TekSecure on a MSO/DPO/MDO4000 Series oscilloscope?

This procedure for clearing the memory on oscilloscope can be applied to the DPO/MSO/MDO4000, DPO/MSO3000 and DPO/MSO2000 Series oscilloscope families. By clearing the memory you will lose all saved reference waveforms, saved setups and all other settings the scope was holding. Please be sure to save all information from the scope before doing a Teksecure errase.
