last page of this instruction manual and push then "P" key. If the password
entered is wrong, the instrument go back to the previous control state.
P.A. :
Always go regularly out from the programming phase because, if the
instrument is switched off during the programming, at the next start-up
could
be signalled the memory error "Err EEPr", To re-establish the
functioning occurs then to push "LEFT" key.
