1. Press the ► Menu button. The blinking  mnemonic shows that
the device is asking for the code.
2. Four zeros appear: . The zero at the left side is blinking.
3. Use the ▲ and the ► buttons, type in either the user code or the
supervisor code.
4. Press the ◄ Esc button. If a correct code has been type in, the
mnemonic  (login as a user) or the mnemonic  (login as a
supervisor) is displayed and stays there for 2.5 seconds; then the first
menu item is shown on the display: .
5. If an incorrect code has been typing in, the mnemonic  (BAD
Code) is shown on the display and stays there for 2.5 seconds; then
the instrument exits from the menu.
Start typing the code in again from Point 1.
If no buttons are pressed, the instrument displays the mnemonic
 (Auto Escape) after 5 minutes has passed from the last
pressing of a button, and goes back to the measuring mode. This
solution is due to security: unauthorised persons, after 5 minute, will
not be able to change the settings of the instrument, should it be left
alone for some reason.
