Dear Sir/Madam, 

could you give me a good guide on a stepwise directive of changing the setting of my second handed machine from German to English.

The interpreted ECG results come in German which non of us here understand.

We procured the machine from Poland via a friend.

I shall be very glad to reveive your prompt advice.
