Understanding VOR tuning!

I am new to flight sim navigation, and there is a few things I yet do not understand.
When tuning the NAV receivers to the frequencies of the VOR stations, for example the Manchester VOR frequency is 114.4 MHZ, the guide books extra always gives a "ident" with the frequency for example Manchesters is ident "MHT". Do I have to input these ident letters into the Nav receiver anywhere, or have I only to tune into the given frequency?
I would appreciate it if someone can help me here.
Thanks
Steve
