User Manual for LED Digital Clock Product description  Clock function: Displaying hour and minute, able to convert between 12 and 24-hour formats.  Date function: Displaying month, day, year (from 2000 to 2099)  Alarm clock function: Setting alarm and snooze every day  Temperature function: Displaying fahrenheit or celsius degree, and able to switch between them. The normal measurement scope is -10oC ~ +50oC (14oF ~ 122oF)  Brightness function: Pressing the key can switch between 3 grades of brightness and close the screen.  CDS function: automatically detect the intensity of external light to adjust LED brightness, able to automaticaly switch betweep 3 grades of brightness  Function of memorizing time in power outage: The clock installed with the 2032 battery can normally work automatically when it is not powered, yet the LED screen displays nothing  Operating voltage: DC5.0V; memory battery is CR2032.

Description of keying function  SET: Long press the SET key to enter the setting state to set time, date, temperature unit in turn, adjust set values via UP/DOWN key  "+" (UP key) up-regulating key, press it in the setting state to up-regulate the numerical value of the object: press it in the normal mode to regulate the brightness: L-AU  L-01  L-02  L-03  close displaying; long press to switch between the two displaying modes.  "-" (DOWN key) down-regulating key, press it it. the normal state to down-regulate the numerical value of the object, press it in the normal mode to close or start the alarm function, and long-press it to enter the alarm time setting.  CDS function: automaticaly detect the intensity of external light to adjast LED brightness when the brightness is L-AU, 3 grades of intensity are available.

Operation instruction  Setting of time, date and temperature unit o In the normal clock mode, long press SET key for about 3s to enter the time setting, then the corresponding setting item flashes, set by the following order via UP/DOWN key, press it to quickly Increase/decrease. No pressing for 5s will exit the setting state, and the currently set timer is displayed. 12/24h switching hour minute month day year temp unit exit o The point for PM becomes ON when the clock is switched to 12-hour format o In the normal clock made, long-press UP key to switch between two modes of dP-1 and dP-2.  DP-1 mode: The LED screea automadically switches cyclically between the time, date and temperature  DP-2 mode: The LED screen fixedly displays the time state.  Setting of alarm and snooze time: o In the normal dock mode, press the DOWN key to check alarm time, then long-press the DOWN key for about 3s to enter the mode of alarm setting set by the following arder via UP/DOWN key in conjunction with the SET key, press it to quickly increase/decrease. No pressing for 5s will exit the setting state and return to the time mode. Hourminutesnooze timeexit o In the normal clock mode, press the DOWN key to turn ON/OFF the alarm, after the alarm is turned ON, the alarm sign becomes ON on the clock interface. o When arbitrary alarm time is up, the clock automatically returns to this alarm mode and emits the sound of "DIDIDID”. When the clock is in the clock mode and the alarm sign flashes, no pressing for 1min will stop the alarming and automatically start the snooze mode, and the alarm sign flashes.

o The time interval for snooze is 5min by default, and S-05 is displayed; the snooze interval can be set as 5-60min; numberless snoozings can be realized. o Alarming duration: Press any key to make the alarm sign flash three times to stop alarming without entering the snooze mode During the snooze period, press the DOWN key to turn off the clock. o After electrified, the clock automatically detect the curent ambient temperature. The normal measuring range is -10oC – 50oC (14oF – 1220F)  The function of brightness adjustment o In the normal clock mode, press the UP key to enter the brightness adjustment state. Three grades of brightness are available o Press the UP key to adjust the brightness: L-AUL-01L-02L-03Close displaying cycle like this. o The clock automatically detects the intensity of external light to adjust LED brightmess when the brighttness is L-Au, 3 grades of intensity are available. o In the state of brightness adjustment, the user can only not press for 3s to exit the setting and save the set brightness.

Electrical parameters:  Requirements on power adapter Input voltage: AC110V-AC24V 50/60HZ  Operating temperature -10oC ~ +50oC
