Hi dear forumers,
A few weeks ago I’ve purchased my third Power Jack inverter, this time a LF4000W-ASL2 model… 😊
Unfortunately it stays at the 60Hz frequency despite depressing for two seconds the second black button on the panel. Two bips are issued but it stays always at 60Hz.
Of course I’ve tried several times because I know it is a toggle process between the 50Hz, 60Hz and automatic modes !
Last but not least, depressing the first black button to select the Chinese or the English language doesn’t work at all, but this is a minor problem.
So please, is it a way to force the 50Hz mode, otherwise I can’t operate several devices with it and thus it is yet completely useless ?
Thanks in advance for your awaited and appreciated help and kind regards,
Germain
