I bought an AppRadio 4 from US and used in Hong Kong recently.

i found that the clock cannot be set to HK local time.

and FM radio only can be tuned at odd freq band. In HK, odd and even freq band both are used for radio station

ANyone can help me?

Nothing you can do. Tuners and models made here for the US are very different from overseas models made for the Euro and other country markets.
