3. Asennus

3.1 Pakkauksesta purkaminen

Carefully remove all components from the packaging. Ensure you have the main atomic clock unit and the wireless outdoor sensor.

3.2 Akun asennus

Both the main clock unit and the wireless outdoor sensor require batteries (not included).

1. Pääkelloyksikkö: Open the battery compartment on the back of the clock. Insert 3 x AA paristotvarmistaen oikean napaisuuden (+/-).
2. Langaton ulkoanturi: Open the battery compartment on the back of the sensor. Insert 2 x AAA paristot, ensuring correct polarity (+/-). For temperatures below -4°F (-20°C), lithium batteries are recommended for the outdoor sensor.

4. Käyttöohjeet

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 Ajan ja päivämäärän manuaalinen asettaminen

In areas where the WWVB signal is weak or unavailable, you can manually set the time and date:

1. Paina ja pidä painettuna SARJA -painiketta siirtyäksesi ajan asetustilaan.
2. Käytä UP or ALAS -painikkeita säätääksesi vilkkuvaa arvoa (esim. tunti, minuutti, vuosi, kuukausi, päivä).
3. Paina SARJA button to confirm each setting and move to the next.
4. The clock will exit setting mode automatically after a few seconds of inactivity or by pressing SARJA toistuvasti, kunnes kaikki asetukset on vahvistettu.

4.3 Lämpötilanäyttö (°C/°F)

The clock displays both indoor and outdoor temperatures. To switch between Celsius (°C) and Fahrenheit (°F):

• Paina DOWN/WAVE/°C/°F button to toggle the temperature unit.

4.4 12/24 tunnin muoto

To switch between 12-hour and 24-hour time formats:

• Paina UP -painiketta vaihtaaksesi 12 tunnin (AM/PM-ilmaisimella) ja 24 tunnin muotojen välillä.

4.5 Hälytystoiminto

Herätyksen asettaminen:

1. Paina HÄLYTYS -painiketta kerran nähdäksesi nykyisen herätysajan.
2. Paina ja pidä painettuna HÄLYTYS -painiketta siirtyäksesi hälytyksen asetustilaan.
3. Käytä UP or ALAS painikkeita tuntien ja minuuttien säätämiseksi.
4. Paina HÄLYTYS -painiketta vahvistaaksesi jokaisen asetuksen.

Hälytyksen kytkeminen päälle/pois päältä:

• Paina HÄLYTYS button repeatedly to cycle through alarm ON/OFF states. An alarm icon will appear on the display when activated.

5. Huolto

5.1 Pariston vaihto

When the low battery indicator appears on the display, replace the batteries in the respective unit (main clock or outdoor sensor) promptly to ensure continuous operation and accurate readings. Refer to Section 3.2 for battery types and installation.

5.2 Puhdistus

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 Ympäristönäkökohdat

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. Vianmääritys

• Ei näyttöä / Himmeä näyttö: Check battery installation and replace with fresh batteries if necessary. Ensure correct polarity.
• Ei ulkolämpötilan lukemaa:
  1. Varmista, että paristot on asennettu oikein ulkoanturiin.
  2. Verify the sensor is within the 330ft wireless range of the main unit.
  3. Paina KANAVA button on the main unit to ensure it is on the correct channel (if applicable).
  4. Relocate the sensor or main unit to improve signal reception, avoiding large metal objects or other electronic devices.
• Väärä aika:
  1. Ensure the clock is attempting to receive the WWVB signal (look for the RCC reception icon).
  2. Place the clock near a window and away from electronic interference for better signal reception.
  3. Manually initiate a signal search by pressing the DOWN/WAVE -painiketta.
  4. If atomic synchronization fails, manually set the time as described in Section 4.2.
• Temperature Readings Seem Inaccurate:
  1. Varmista, että ulkoanturi on sijoitettu varjoisaan paikkaan, poissa suorasta auringonvalosta tai lämmönlähteistä.
  2. Tarkista molempien laitteiden akun varaustaso.
