4 Parameters 

4.1 

Select parameter configuration 

The configuration parameters can be protected by a numerical password. A value of “0” 
disables this protection (default password: 12). To select the parameter configuration: 
 

 

Press the 

PRG

 button for more than 5 seconds  

 
In case of password value equal to “0”: 

 

The first modifiable parameter code is displayed (/1). 

 

To modify parameters see “Parameter modification” below. 

 
In case of password value not equal to “0”:  

 

A flashing 0 is displayed 

 

Press   or   until the password value is displayed.

4.2 Parameter 

Modification 

 

Press    or   to show the code of the parameter that has to be changed; 

 

Press 

SEL

 to display the selected parameter value;  

 

Press   or   to increase or decrease the value; 

 

Press 

SEL

 to temporally confirm the new value and display its code 

 
Repeat the procedure from the beginning "

press   or   to show..

." to modify another 

parameter, etc. 
 
To exit modifying the parameters with the new values: 

 

Press 

PRG

 to confirm the new values and exit the parameter modification 

procedure. 

 
To exit without modifying any parameter: 

 

Do not press any button for at least 60 seconds (TIME OUT). 

 

4.3 Special 

Functions 

 

Press   and   together for more than 5 seconds: a flashing “0” is displayed.
