A Vortech Tip - I picked up & I thought I would share here... don't know if everyone that has one already knows this, but if not, might help... for like when you want to stop it for a brief feeding period. It not a published tip, but something the EcoTech TECH guys shared when called... If Interested ... give it a try & report back ! To put it into standby, hold down Mode + Set at the same time. Lights will start flashing red/blue/white. At that point, it is in standby. To get it back to normal, press and hold down Mode until it flashes red/purple (depending on mode) and then press Mode one more time and you are back to normal.
