it's really easy - whoever looks bad is alerted about the color!

... But you could work on the packaging or something. The actual device is located in a kind Bliesterpackung which you can tear at one point of the carton easy ... at least in theory. In practice, the cardboard ripped everywhere, just not there where they should be ... until I almost had confetti in front of me ... ;-) But well, it's even unpacked, no longer grabs you it a yes.

The device itself is briefly switched on by pressing a button, and then voted on the button between people up to 3 months / 3 months to 36 months / and everything about it. Then clamp the tip under the armpit. After a short beep, you can read the number and when it is highlighted in green, everything is just in the "green area".

If not, you have either done something wrong, or is really sick :-(

One can particularly flexible tip under the arm, use orally or rectally. Since the device is easy to clean, it can be disinfected quickly.

The color range is red, yellow or green in the diagnosis. Very reasonable. (Also for partially sighted people to recognize good!)

As a power source (already Enclosed) is a button cell
Great, precise and hygienic thing!
