Zz flashed together, only Zz was flashing while waiting for snooze.)
1. Press once to switch from the time/date interface to the ALM interface. Press and hold for 2 seconds to set the hour and minute of the alarm. As long as there is a setting, the alarm will be activated.
2. When the highest/lowest temperature and the corresponding humidity are displayed, press the ALM/CLEAR button to clear the displayed maximum/minimum temperature and relative humidity, and automatically return to the current temperature and relative humidity display mode after 3 seconds;
1. On the interface displaying time, press to switch ℃/℉;
2. On the interface displaying time, press and hold for 2 seconds to switch the 12/24 hour system;
Press MAX/MIN once to display the highest temperature and relative humidity display mode, press MAX/MIN once to display the lowest temperature and relative humidity display mode, then press MAX/MIN once to return to the current temperature and relative humidity display mode. In the MAX or MIN display mode, if there is no button for 8 seconds, it will automatically return to the current temperature and relative humidity display mode.
