4. Naudojimo instrukcijos
4.1 Atomic Time Synchronization (WWVB)
The clock automatically synchronizes with the WWVB radio broadcast from Fort Collins, Colorado, ensuring accurate time. This process typically occurs overnight. For best reception, place the clock near a window and away from electronic interference.

Image 4.1: The atomic clock automatically corrects its time daily by receiving the WWVB signal, covering eight time zones and adjusting for Daylight Saving Time.
4.2 Rankinis laiko ir datos nustatymas
In areas where the WWVB signal is weak or unavailable, you can manually set the time and date:
- Paspauskite ir palaikykite NUSTATYTI mygtuką, kad įjungtumėte laiko nustatymo režimą.
- Naudokite UP or ŽEMYN mygtukais reguliuokite mirksinčią reikšmę (pvz., valandą, minutę, metus, mėnesį, dieną).
- Paspauskite NUSTATYTI mygtuką, kad patvirtintumėte kiekvieną nustatymą ir pereitumėte prie kito.
- The clock will exit setting mode automatically after a few seconds of inactivity or by pressing NUSTATYTI repeatedly until all settings are confirmed.
4.3 Temperature Display (°C/°F)
The clock displays both indoor and outdoor temperatures. To switch between Celsius (°C) and Fahrenheit (°F):
- Paspauskite DOWN/WAVE/°C/°F button to toggle the temperature unit.
4.4 12/24 valandų formatas
Norėdami perjungti 12 valandų ir 24 valandų laiko formatus:
- Paspauskite UP mygtuką, norėdami perjungti 12 valandų (su AM/PM indikatoriumi) ir 24 valandų formatus.
4.5 Aliarmo funkcija
Norėdami nustatyti žadintuvą:
- Paspauskite SIGNALAS mygtuką vieną kartą, kad būtų rodomas dabartinis žadintuvo laikas.
- Paspauskite ir palaikykite SIGNALAS mygtuką, norėdami įjungti aliarmo nustatymo režimą.
- Naudokite UP or ŽEMYN mygtukais, kad sureguliuotumėte valandas ir minutes.
- Paspauskite SIGNALAS mygtuką, kad patvirtintumėte kiekvieną nustatymą.
Norėdami įjungti / išjungti žadintuvą:

5.2 Valymas
Clean the clock and sensor with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the display or casing.
5.3 Aplinkosaugos aspektai
The outdoor sensor is designed for outdoor use but should be protected from extreme weather conditions. The recommended operating temperature range for the outdoor sensor is -58°F to 158°F (-50°C to 70°C). For temperatures below -4°F (-20°C), lithium batteries are required in the outdoor sensor for reliable performance.
6. Problemų sprendimas
- Nėra ekrano / silpnas ekranas: Check battery installation and replace with fresh batteries if necessary. Ensure correct polarity.
- Nėra lauko temperatūros rodmenų:
- Įsitikinkite, kad lauko jutiklyje baterijos yra tinkamai įdėtos.
- Verify the sensor is within the 330ft wireless range of the main unit.
- Paspauskite KANALAS button on the main unit to ensure it is on the correct channel (if applicable).
- Relocate the sensor or main unit to improve signal reception, avoiding large metal objects or other electronic devices.
- Neteisingas laikas:
- Ensure the clock is attempting to receive the WWVB signal (look for the RCC reception icon).
- Place the clock near a window and away from electronic interference for better signal reception.
- Manually initiate a signal search by pressing the DOWN/WAVE mygtuką.
- If atomic synchronization fails, manually set the time as described in Section 4.2.
- Temperature Readings Seem Inaccurate:
- Įsitikinkite, kad lauko jutiklis yra padėtas šešėlinėje vietoje, atokiau nuo tiesioginių saulės spindulių ar šilumos šaltinių.
- Patikrinkite abiejų įrenginių baterijų lygį.
