ביטע זיכער מאַכן אַז אַלע זאכן זענען פאַראַן איידער איר גייט ווייטער מיט דער סעטאַפּ:
- MARATHON Slim Atomic Wall Clock (Model CL030027-FD-WD)
- ווירעלעסס דרויסנדיק טעמפּעראַטור סענסאָר
- 4 x AA Batteries (for clock and sensor)
- ינסטרוקטיאָן מאַנואַל (דעם דאָקומענט)
סעטאַפּ אינסטרוקציעס
1. באַטאַרייע ייַנמאָנטירונג
- For the Main Clock: Open the battery compartment on the back of the clock. Insert the specified AA batteries, observing the correct polarity (+/-).
- פֿאַר דעם דרויסנדיקן סענסאָר: Open the battery compartment on the back of the wireless sensor. Insert the specified AA batteries, observing the correct polarity (+/-).
- Close both battery compartments securely.
Note: It is recommended to insert batteries into the outdoor sensor first, then into the main clock, to ensure proper synchronization.
2. ערשטע אויפשטעל און אטאמישע צייט סינקראניזאציע
Upon battery installation, the clock will automatically begin searching for the atomic time signal (WWVB) and the outdoor sensor signal. This process may take several minutes to several hours, depending on your location and environmental conditions.
- Place the clock near a window for better signal reception during initial setup.
- A signal icon (often resembling a radio tower or waves) will appear on the display when the atomic signal is being received.
- Once synchronized, the time, date, and day will automatically set.

3. דרויסנדיקע סענסאָר פּלאַצירונג
For accurate outdoor temperature readings, position the wireless sensor in a sheltered location outside, away from direct sunlight and precipitation. Ensure it is within the transmission range of the main clock (typically up to 100 feet/30 meters, line of sight).
- Avoid placing the sensor near large metal objects or electrical appliances that may interfere with the signal.
- If the outdoor temperature does not display, press the "Sensor" or "Channel" button on the main clock (if available) to re-establish connection, or re-insert batteries in both units.
4. מאַונטינג אָפּציעס
- וואנט בארג: Use the integrated keyhole slots on the back of the clock to hang it on a screw or nail securely fastened to a wall.
- Desktop Display: Extend the built-in foldable stand on the back of the clock to place it on a flat surface.

אַפּערייטינג ינסטראַקשאַנז
1. Setting Time Zone
After atomic synchronization, you may need to adjust the time zone. Locate the "TIME ZONE" or "ZONE" button on the back of the clock. Press this button repeatedly to cycle through the available 8 time zones until your local time zone is displayed.
2. 12/24 Hour Format Selection
To switch between 12-hour (AM/PM) and 24-hour (military) time formats, locate the "12/24H" button on the back of the clock and press it once.
3. Temperature Unit Selection (Celsius/Fahrenheit)
To change the temperature display between Celsius (°C) and Fahrenheit (°F), locate the "°C/°F" button on the back of the clock and press it once.
4. Daylight Saving Time (DST) On/Off
The clock typically adjusts for DST automatically. However, if you reside in an area that does not observe DST, or if you wish to manually override this feature, locate the "DST" button on the back of the clock and press it to toggle the function on or off.
5. Manual Time Setting (If Atomic Sync is Unavailable)
In areas where the atomic signal is weak or unavailable, you can manually set the time and date:
- Press and hold the "SET" or "MODE" button until the time display begins to flash.
- Use the "+" or "-" buttons to adjust the flashing digit (e.g., hour, minute).
- Press "SET" or "MODE" again to confirm the setting and move to the next adjustable parameter (e.g., minute, year, month, day).
- Repeat until all desired settings are configured, then press "SET" or "MODE" one last time to exit manual setting mode.
ווייַז אינפֿאָרמאַציע
The clock's display is designed to provide all essential information at a glance:
- צייט: Large digits display the current time (hours, minutes, seconds). AM/PM indicator for 12-hour format.
- טאָג פון דער וואָך: Full day name (e.g., TUESDAY).
- טאָג: Month and day (e.g., JUL/30).
- דרינענדיק טעמפּעראַטור: Current temperature measured by the main clock unit.
- דרויסנדיק טעמפּעראַטור: Current temperature received from the wireless outdoor sensor.
- Atomic Signal Indicator: Icon indicating successful atomic time synchronization.

וישאַלט
- רייניקונג: Wipe the clock and sensor with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- באַטערי פאַרבייַט: Replace all batteries in both the main clock and the outdoor sensor when the display becomes dim or unresponsive. Always replace with fresh, high-quality AA alkaline batteries.
- ינווייראַנמענאַל טנאָים: Avoid exposing the clock to extreme temperatures, direct sunlight for prolonged periods, or high humidity. The outdoor sensor is weather-resistant but should be placed in a sheltered area.
