My Review: This Digital Indoor/Outdoor thermometer and humidity hygrometer allows me to be able to see the current humidity levels inside. The probe (from what I can tell) is for measuring the temperature outside. It displays both inside and outside temperature when you have the probe outside, but the humidity sensor is in the main device.
The instructions are REALLY confusing and not well made. Luckily another reviewer received help from them, and I will include it in my review as well. Over all the dual thermometer is really nice, but I really wish the probe would tell the humidity outside instead of inside.
-How to set time-
Under original state, press the [MODE] for 2 seconds, the Minutes number begin to twinkle, then press the [ADJ] to adjust the Minutes number. When the Minutes set up, press the [MODE], the Hour number begin twinkle, then press [ADJ] to set Hour.

Then use [MODE] to set Month(M) and Day(D).
-The way to set Alarm-
Under current clock, press [MODE], the “Bell logo” appears, then press [ADJ], the “.)))” appears, when both logo in the screen, the number begins to twinkle, you can adjust the Alarm time. The humidity meter will automatically get back current clock in 1 minute if no any operation.
