HI, like many owners of the Zettle terminal I used mine a year ago and then circumstances dictated no more fairs for a year. Ready to get back on the show circuit I unboxed my Terminal, which is in pristine condition only having been used for one day last year and put it on charge with the supplied lead and plug only to find the same locked screen message. I approached customer service and although they were very helpful they suggested the problem was caused by the unit draining and this trigered the security alert. Nothing I tried, holding down buttons, reset etc helped. The only alternative was to purchase a new unit, which, after seeing all the complaints about the issue, i was not happy to do.
Anyway, after several days I decided the unit was un fixable. I intended to see if I could connect it to my PC via a USB lead , not the one supplied with the unit. I have a samsung mobile phone which fitted into the unit but was still plugged into the mains via a USB plug for my phone. Once plugged in the unit burst into life with the set up option...no more security warnings. Waiting for it to charge completely before giving it a go...fingerd crossed.
