5. Asennus

5.1 Akun asennus

1. Avaa kellon takana olevan paristolokeron kansi.
2. Insert 3 C batteries, ensuring correct polarity (+ and -).
3. Sulje paristolokeron kansi.

5.2 Initial Synchronization and Settings

Upon battery installation, the clock will automatically attempt to synchronize with the NIST atomic clock signal. This process may take several minutes to several hours, depending on your location and signal strength. The atomic feature only functions in North America.

1. Aikavyöhykkeen valinta: Use the Time Zone switch on the back of the clock to select your local time zone (AST, CST, EST, MST, NST, PST).
2. Kesäaika (DST): Set the DST switch to ON or OFF according to your region's DST observance.
3. Lämpötilayksikkö: Select Celsius or Fahrenheit using the dedicated switch.
4. Sijoitus: For optimal signal reception, place the clock near a window and away from electronic devices that may cause interference.

5.3 Asennusvaihtoehdot

The clock can be wall-mounted or placed on a flat surface using its built-in stand.

• Seinäkiinnitys: Use the keyhole slot on the back of the clock to hang it securely on a screw or nail.
• Pöytäteline: Extend the built-in stand from the back of the clock for desktop or shelf placement.

6. Kellon käyttö

6.1 Automatic Time Synchronization

The clock automatically receives the atomic time signal from NIST's Colorado Atomic Clock. This ensures accurate timekeeping without manual adjustment. The signal icon on the display indicates reception status.

• A solid signal icon indicates successful synchronization.
• A flashing icon indicates the clock is attempting to receive the signal.

6.2 Manual Time and Date Adjustment

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

1. Locate the manual set buttons on the rear panel.
2. Press the 'SET' button to enter setting mode.
3. Säädä vilkkuvaa arvoa (esim. tunti, minuutti, vuosi, kuukausi, päivä) '+'- tai '-'-painikkeilla.
4. Vahvista ja siirry seuraavaan asetukseen painamalla uudelleen 'SET'-painiketta.
5. Exit setting mode by not pressing any button for a few seconds, or by cycling through all settings.

6.3 Näyttötilat

• 12/24 tunnin muoto: The clock supports both 12-hour (with AM/PM) and 24-hour time displays. This setting can typically be toggled via a button on the rear panel or during manual setup.
• Lämpötilanäyttö: Switch between Celsius (°C) and Fahrenheit (°F) using the dedicated switch on the back.

7. Huolto

7.1 Puhdistus

Puhdista kello pehmeällä, kuivalla liinalla. Älä käytä hankaavia puhdistusaineita tai liuottimia, sillä ne voivat vahingoittaa näyttöä taiasing.
