Although the use and the various settings are not complicated, a notice would be superfluous.
- Indeed, there is a switch "sensor" that one wonders what it is: in the "touch"? I do not believe because if it is Off it still works! Maybe then the temperature function ???
- Then when the alarm is triggered its judgment is good when you touch the upper part of "Touch", BUT then it reproduces every 5 minutes (I tested). For it is necessary to finalize the switch "G-ON / OFF" on the back to Off. This is not very convenient and that's why I do not put it 3 stars.
- There is also a small LED on the back that's the point ???
Also note that the LCD display is optimized when the alarm is placed lower than your eyes, that is, if you place it on a fairly high bedside table display is less clear, although visible. And backlight (which automatically after a few seconds) increases this defect.
I do not know what the battery life, but there is a socket in the back to power with a 5v power supply connected to the mains, or USB.
For the price I still recommend this awakening to those who would not be bothered by the final stop mode of the alarm.
Rectification Last Minute switch "sensor" is used to put into operation a weak backlight when the room is dark / black, and what I took for an LED at the rear must be its sensor light.
