How can i ZOOM-IN application menu in SAP ITS?

I am using a CK71 with Wavelink client to access customer's SAP ITS web, but i can not adjust size of SAP ITS in Wavelink client. i attach my Wavelink config file and put a screenshot for reference.

Here is my device version: CK71 with OS 1.50 Chinese,

Wavelink client:WLTE_ITC_CK71_WM6_LANG_7_3_237_AS.exe.

Any solution for that?

Thanks,
