i have crane with following specification :
type ; ATF \20-S
S\N : 12505
the problem in this crane when you want to change code configuration for example if you want to put code 17 via select operating mode button and put the code (17 or 18 or any code )and press C button on console the console does not appear the right code which had been entered before but it appears 2018 or 2019 etc
and olso the same when i put 0018 or 0019 or other dicemal code it appears the same 2018 or 2019 or2020 and the LMI is DS350
so would you please if you can advice me about this problem .
