FAIL ERROR during LASER RADIATION - "Over/ Under Power" - On Screen Error - 25. freq Error

Hello  !!!

Have somebody faced a Fail error during LASER RADIATION on Alma Lasers - Soprano PLATINUM.

During the LASER RADIATION application, the machine stops and a message on the screen appears as "Over/ Under Power"  and on the  screen error: "25. freq Error".

Please could somebody help me on this ? 

I also need the service manual for the Alma Lasers - Soprano PLATINUM ? 

Best regards .
