How do I enter a xxx.xxxx in ARC160 ?

[GregHiggins]

Just purchased a 160 and the ARC160 software. While trying to enter frequencies that have 4 numbers after the decimal (ex.: 151.1525) the ARC160 software changes it to a 151.1500. There are several frequencies that this happens. What is the solution to this problem?? Thanks!
