Organizować coś

1. Włączanie jednostki głównej

The Sharp Atomic Clock can be powered via the included AC adapter for an "always on" display or by batteries for an "on-demand" backlight function.

• Zasilanie prądem zmiennym: Plug the provided 110V/120V AC adapter into a standard household wall outlet and connect it to the clock. This will provide continuous power and an always-on backlight.
• Zasilanie bateryjne (opcjonalnie): For battery operation, insert three (3) AA batteries (not included) into the battery compartment located on the back of the main unit. When operating on battery power, the backlight will illuminate for 5 seconds when the BACKLIGHT button is pressed.

2. Setting Up the Wireless Outdoor Sensor

The wireless outdoor sensor transmits outdoor temperature readings to your main clock unit.

• Insert two (2) AAA batteries (not included) into the wireless outdoor sensor.
• Place the sensor in a shaded, dry location outdoors, away from direct sunlight and sources of heat or moisture. Ensure it is within 100 feet of the main unit for optimal signal reception. Avoid placing it near metal objects, which can interfere with readings.

3. Początkowa synchronizacja czasu atomowego

The clock is designed to automatically synchronize with the WWVB radio signal from Fort Collins, Colorado, ensuring atomic accuracy.

• After powering on, the clock will begin searching for the WWVB signal. The atomic signal icon will flash on the screen during this 7-minute search.
• If the signal is acquired, the icon will stop flashing. If not, the clock will attempt to connect again, typically overnight when interference is minimal. Full synchronization may take up to 48 hours.
• For best reception, place the clock along a wall or near a window that faces Fort Collins, Colorado. Avoid placing it near electronic devices (computers, power lines, vehicles) that can cause interference.

4. Setting Time Zone and Daylight Saving Time (DST)

After initial synchronization, ensure your time zone is correctly set. The clock supports multiple time zones (Pacific, Mountain, Central, Eastern, and potentially Alaska & Hawaii).

• Press the "TIME ZONE" button (usually labeled "UP TIME ZONE" on the back) to cycle through available time zones until yours is displayed.
• If you reside in an area that does not observe Daylight Saving Time (e.g., Arizona, Hawaii), ensure DST is disabled on your clock. Refer to the full instruction manual for specific steps on disabling DST if this feature is available on your model.

Instrukcja obsługi

Funkcje wyświetlacza

The clock's bright color display provides clear visibility of essential information:

• Czas: Jumbo 3-inch tall numbers for easy reading.
• Temperatura wewnętrzna: Displays the current temperature inside your home.
• Temperatura na zewnątrz: Displays the current temperature from the wireless outdoor sensor.
• Kalendarz: Shows the month, date, and day of the week.

Regulacja jasności

The display brightness can be adjusted to suit your preference. There are typically multiple levels of brightness (e.g., 100%, 50%, 8%, OFF) when the clock is AC powered. When on battery power, the backlight is on-demand for 5 seconds when the BACKLIGHT button is pressed.

Format 12/24 godzinny

To switch between 12-hour and 24-hour time formats, press the "12/24" button on the back of the unit.

Przełącznik Celsjusza/Fahrenheita

To switch between Celsius and Fahrenheit temperature units, press the "°C/°F" button on the back of the unit.

Ręczne ustawianie czasu i kalendarza

In rare cases where the atomic signal cannot be received, you can manually set the time and calendar:

• Kalendarz: Press and hold the "CALENDAR" button for 2 seconds to manually set the calendar. Use the UP/DOWN buttons to change the value of Year, Month, Date, and Language. Press "CALENDAR" again to confirm each setting.
• Czas: Press and hold the "TIME" button for 2 seconds to manually set the time. Use the UP/DOWN buttons to change the value of Hour, Minute. Press "TIME" again to confirm each setting.

Rozwiązywanie problemów

Atomic Signal Reception Issues

If your clock is not synchronizing with the atomic time signal:

• Zmiana położenia: Try rotating the clock 90 degrees. If wall-mounted, try a different wall (e.g., north-south wall instead of east-west).
• Lokalizacja: Place the clock along a wall or near a window facing Fort Collins, Colorado. Ensure it is at least 6 feet away from electronic devices like computers, TVs, or other appliances that emit radio frequency interference.
• Test na świeżym powietrzu: If indoor reception is consistently poor, take the clock outdoors at night (remove batteries first, then plug it in) to force it to search for the WWVB signal. If it works outdoors but not indoors, your building may be causing interference.
• Materiały budowlane: Metal buildings or steel siding can block the signal.
• Manual Wave: Press and hold the "WAVE" button on the back of the clock for 2 seconds to manually initiate a search for the atomic signal.

Outdoor Temperature Sensor Issues

If the outdoor temperature is not displaying or is inaccurate:

• Na nowo połączyć: Remove batteries from both the main unit and the outdoor sensor for 15 minutes. Then, reinsert batteries into the sensor first, followed by the main unit. Place both units side-by-side indoors until their temperatures show within two degrees of each other. Once reconnected, place the sensor back outdoors in its designated location.
• Umieszczenie: Ensure the sensor is in a dry, shaded area, away from direct sunlight, heat sources, and metal objects.
• Kanał: If you have multiple sensors or interference, ensure the main unit and sensor are on the same channel. Use the "CHANNEL" button on the back of the main unit to switch between channels (1, 2, 3) to receive the outdoor sensor's signal.

Ogólne resetowanie

If the clock is behaving erratically, a full reset may resolve the issue. Press the "RESET" button on the back of the unit using a small, pointed object (like a paperclip).

Konserwacja

• Wymiana baterii: Replace batteries in both the main unit and the outdoor sensor when the display indicates low power or when performance degrades. For optimal performance, Duracell batteries are recommended.
• Czyszczenie: Clean the clock and sensor with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Składowanie: Jeśli zegar nie będzie przechowywany przez dłuższy czas, należy wyjąć wszystkie baterie, aby zapobiec ich wyciekowi.
