Yes, it will project time, indoor&outdoor temperature at same time.
No, the package contains one base unit and one outdoor sensor that can detect the indoor and outdoor temperature respectively.
The clock can automatically synchronize the time in areas with strong WWVB signals (for accuracy, we need to set the time zone first, please note that the DST function must be turned ON during daylight saving time, otherwise the time will be off by one hour).
If the WWVB signal is weak, we can also set the time manually.
The setup is very simple and the manual is very detailed.
Yes, when plugged in, we can set the backlight to always be on. I have noticed that some reviews say that the backlight cannot always be on. It may be because they have set the power saving mode (by clicking the light button to turn on for 15 seconds). I suggest that if you encounter a problem, you can directly find the Newentor customer service to solve it. Their service is very friendly and professional.
Yes, there is a radio alarm clock.Newentor projection alarm clock contains 7 time zones: -10HST、 -9AKST、 -8PST、 -7MST、 -6CST、 -5EST -4AST, and we can also set the time manually. Very easy to set it up.
