Hello Gustavo Altamirano,
Thanks for you order. Do you have problem on how to enter setting mode?
1. If you want to check AH or WH parameters, please short press down button to show WH, short press up button to show AH.
2. When it show AH, you can hold OK button to enter setting mode. There are BAT, BPC, OPP and other functions.
Please program it as needed. After setting, please hold OK button to exit setting mode.
For any more questions, please let us know.
Best regards,
