Re: wf 860 cancel test mode
I’m convinced that these machines are going into test mode due to radio interference.
I have one of these machines in a remote area that suffers from voltage drops and spikes.
The machine had gone into test mode every few weeks over the past year or so.TThe customer is old and unable to sort it themselves. They were ok paying me to pop in and reset it but it got a bit stupid.
Last time I called I suggested that the customer buys a surge protector mains socket (like you use to protect the PC from voltage surges) This was over six months ago and I haven’t been back!
