Reset button
In some special circumstances, CEMB customer service may advise you to reset the N300
instrument. To do this, press the button located on the lower part of the instrument using a
small object with a rounded tip. It is purposely located in a difficult to access area to
prevent it from being reset unintentionally.
Warning:
In the event of an error that cannot be reset automatically, the message "Err" will
be displayed on the screen followed by the number identifying the error that
occurred.
Should this situation occur, the instrument must be reset manually by pressing the
reset button.
Warning:
Do not use pointed objects such as needles, punches or suchlike to press the reset
button as they could damage it.
