LFF Atomic Clock User Manual

1. הקדמה

The LFF Atomic Clock (Model LWC150) is a versatile digital wall or desk clock designed for accurate timekeeping and environmental monitoring. It automatically synchronizes with the WWVB radio broadcast for precise time and features a large, easy-to-read LCD display showing time, date, day of the week, alarm status, and both indoor and outdoor temperature and humidity.

2. פֿעיִקייטן

• Accurate Atomic Clock: Built-in receiver automatically synchronizes with the WWVB radio broadcast from NIST in Fort Collins, Colorado, ensuring precise time and calendar adjustments.
• Large LCD High-Definition Display: 9.4-inch tall display with large numbers for easy readability. Displays time (12/24H), calendar, day of the week, alarm, indoor/outdoor temperature (°C/°F), and humidity simultaneously.
• ווירעלעסס דרויסנדיק סענסאָר: Transmits accurate outdoor temperature and humidity measurements up to 328 feet (100 meters). The sensor has an IPX4 splash-proof rating.
• באַטערי אַפּערייטאַד: Main clock requires 4 AA batteries (not included), and the outdoor sensor requires 2 AAA batteries (not included). No backlight display.
• קייפל צייט זאָנעס: Supports 8 time zones including EST, CST, MST, PST, AKT, HST, AST, NST.
• פלעקסאַבאַל אָרט: Can be used as a wall clock (3 hanging holes) or a desk clock (integrated bracket).

4. סעטאַפּ

4.1 באַטאַרייע ייַנמאָנטירונג

The main clock unit and the outdoor sensor are battery-powered. Batteries are not included.

1. For the Main Clock Unit: Open the battery compartment on the back of the clock. Insert 4 new AA batteries, ensuring correct polarity (+/-).
2. For the Wireless Outdoor Sensor: Open the battery compartment on the back of the sensor. Insert 2 new AAA batteries, ensuring correct polarity (+/-).

4.2 דרויסנדיקע סענסארן פּלאַצירונג

For accurate temperature and humidity readings, place the outdoor sensor in a location that is:

• Out of direct sunlight and rain.
• Away from any heat sources (e.g., vents, exhaust fans) or extreme cold sources.
• Within the wireless transmission range of 328 feet (100 meters) from the main clock unit.

4.3 Initial Atomic Time Synchronization

After battery installation, the clock will automatically attempt to synchronize with the WWVB atomic time signal. This process may take several minutes to several hours, depending on your location and signal strength. Ensure the clock is placed in an area where it can receive a clear signal, ideally near a window and away from electronic interference.

5. אַפּערייטינג ינסטרוקטיאָנס

5.1 מאַנועלע צייט און דאַטע איינשטעלונג

While the clock primarily relies on atomic synchronization, you can manually set the time and date if needed (e.g., during initial setup before signal acquisition or in areas with poor reception).

1. דריקן און האַלטן די שטעלן button on the back of the clock until the display flashes.
2. ניצן די UP or DOWN/RCC קנעפלעך צו סטרויערן די בלינקנדיקע ווערט (למשל, שעה, מינוט, יאר, חודש, טאג).
3. דרוק שטעלן again to confirm the setting and move to the next value.
4. Repeat until all desired settings are configured.

5.2 Time Zone Selection

The clock supports 8 time zones. After atomic synchronization, you may need to select your local time zone.

• דרוק די שטעלן button repeatedly until the time zone setting flashes.
• ניצן די UP or DOWN/RCC buttons to cycle through the available time zones (EST, CST, MST, PST, AKT, HST, AST, NST).
• דרוק שטעלן צו באַשטעטיקן דיין סעלעקציע.

5.3 טעמפּעראַטור איינהייט אויסוואַל (°C/°F)

To switch between Celsius and Fahrenheit for temperature display:

• דריקן קורץ אויף די DOWN/RCC button. The temperature unit will toggle between °C and °F.

5.4 וועקער זייגער פונקציע

The clock includes an alarm function.

1. דרוק די שרעק קנעפּל צו view די קראַנט שרעק צייַט.
2. דריקן און האַלטן די שרעק קנעפּל ביז די אַלאַרם צייט בלינקט.
3. ניצן די UP or DOWN/RCC קנעפּלעך צו שטעלן די געוואונטשענע אַלאַרם שעה און מינוט.
4. דרוק שרעק צו באַשטעטיקן יעדער באַשטעטיקן.
5. צו אַקטיווירן/דעאַקטיווירן דעם אַלאַרם, דריק קורץ די שרעק button when the alarm time is displayed. An alarm icon will appear/disappear on the screen.

5.5 ווייַז אינפֿאָרמאַציע

The large LCD display provides comprehensive information at a glance:

• שפּיץ אָפּטיילונג: Current time (with AM/PM indicator), atomic signal strength, DST indicator, and time zone.
• מיטל אָפּטיילונג: Date (Month-Day-Year) and Day of the Week.
• דנאָ אָפּטיילונג: Indoor temperature and humidity, and outdoor temperature and humidity (from wireless sensor).

6. וישאַלט

6.1 באַטערי פאַרבייַט

Replace batteries in both the main unit and the outdoor sensor when the display becomes dim or readings become erratic. Always replace all batteries at the same time with new ones of the same type. For temperatures below -4°F, lithium batteries are recommended for the outdoor sensor.

6.2 רייניקונג

Wipe the clock and sensor with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the display or casing. Avoid getting moisture into the battery compartments or electronic components.

6.3 סענסאָר זאָרג

Periodically check the outdoor sensor for any debris or obstructions that might affect its readings. Ensure it remains in a sheltered location to protect it from extreme weather conditions, despite its splash-proof design.
