Hi I'm having problems with the programming of the Huanyang inverter. I think I have the wiring right, but I cannot programme it.

I was instructed to set the following:
PD0013 to 8
PD005 to 400
PD004 to 400 and
PD003 to 400
I press the prog button then the up value till it reads Pd0013
put I cannot input the 8
I would be most grateful if you could help with how to use the keypad
