we are having a demo machine in OT to be appraised for possible purchase.
the briefing on the operation of this machine was given by the vendor some days back & we're taking turns to use & get familiar with it.
i thought it was the pilot light, which is normally switched on when the main OT lights are switched off during certain procedures. we weren't doing any of those procedures, so i proceeded to switch it off.
the machine suddenly stopped & the screen went blank. as it turned out, what i thought was the pilot light was actually the power on-off button. good thing the vendor was present & she immediately pressed the button again & the machine came to life. phew!
i've often chastised my assistants that they shouldn't do things if they are not sure how or when they should be done & to ask 1st if unfamiliar with the procedures.
looks like i should heed that advice myself. after all, when you point one finger at someone, three other fingers are pointed back at you.
i bowed my head in shame.
