The last hilton I was in the time was off by a few hours, so I popped off the top and adujsted it. I believe the instructions are printed in othe inside of the cover plate in impossible to read black raised type on the black plastic, but if you carry a screwdriver, you probably have enough brains to figure it out.
I can not believe that they designed a clock radio where you can not change the time or the stations. While I usually use my cell as an alarm clock, I prefer the clocks in the room to have the correct time on the display. They could have at least gone to a solution where the clocks set themselves from the standard time signals.
There are no country stations in New York, yet the radios have a country button. How stupid is that, and i've never seen it programed with a station (at least on my arrivial).
What is funny, is that I've gotten a repeat room and the stations I've changed it to have all been there months later.
