recommended to activate the keys at right angles to the front. Touching them from the side
can cause incorrect operation.
• After 5 minutes of inactivity, there is an automatic return to measuring mode. Previously
changed data is not saved.
• Step over from optical- to push buttons is directly possible. After using push buttons, wait
several minutes before the optical buttons become active again.
