Otherwise the alarm following functions not contained in the description has:
- 2 display modes: permanent time / temperature or a change between Z / T (10 sec) and the date in the format YYYY / MM / DD (5 sec)
- Exchange between the mentioned here noise operation, which in my opinion, but not recommended due to the high volume and necessary alternative continuous operation
- The brightness of the display can be adjusted in 4 different dimming levels
- 4 possible alarm times can be set - Alarm and Alarm 1-3 weekdays (How this funkionieren I have not tried), all without snooze function
- Switch between ° C and ° F for temperature display
The manual is in Chinese and Google Translator-English exist (sample: Keep dropping down from floors, in case there is any broken), but with a little imagination and technical knowledge, it is not a problem, make adjustments.
What you should be concerned about, is probably necessary in most cases USB adapter for the socket, which is not included - or an alternative power cable to the 5V connection or batteries
