Setting and displaying FACTORY-SET parameters
Factory-set parameters are configuration parameters and so they are protected by a password to prevent any unauthorized
access to the data. Press PRG and SEL simultaneously for more than 5 seconds to enter the factory-set parameters (unit
configuration parameters) menu. This section is protected by a code (password), which is different from the User one, to
prevent any unauthorized access to the data. Setting the password: "00" flashes on the display. Pressing the
and
buttons will allow you to stop the blinking effect for a few seconds and select the password value; then press SEL to directly
enter the factory-set parameters section. On setting the password, the display will automatically flash after a few seconds if
no buttons are pressed. FACTORY-set parameters selection: the display shows the code of the factory-set parameter that
can be modified. Pressing
and
allows to scroll all factory-set parameters. Press SEL again to display the required
Factory parameter and modify its value (with the
and
buttons).
Press PRG to store the modified parameters and exit the procedure, while the SEL button allows to return to the Factory
parameters menu. On setting the parameters, the display will automatically flash after a few seconds if no buttons are
pressed. If you do not press any button within 60 seconds after having entered this procedure, the unit will return to normal
operation without storing the values of the modified parameters.
