Opsætning
1. Batteriinstallation
- Locate the battery compartment on the back of the clock (refer to Figure 2).
- Åbn batterirummets dæksel.
- Isæt de to AAA-batterier, og sørg for at polerne vender korrekt (+ og -).
- Luk batterirummets dæksel forsvarligt.
Upon battery installation, the clock will automatically begin searching for the atomic time signal.
2. Atomic Time Synchronization
- Placer uret i nærheden af et vindue for optimal signalmodtagelse.
- The clock will attempt to synchronize with the NIST radio signal. This process may take several minutes to a few hours, depending on your location and environmental conditions.
- A signal strength indicator (often a tower icon) on the display will show the reception status. A solid icon indicates successful synchronization.
- If the clock does not synchronize after several hours, try relocating it to a different position or window.
3. Indstilling af tidszone
Once synchronized, the clock will display the default time zone. To adjust:
- Locate the "TIME ZONE" button on the back of the clock (refer to Figure 2).
- Press the "TIME ZONE" button repeatedly to cycle through the available North American time zones: Pacific (P), Mountain (M), Central (C), Eastern (E), Atlantic (A), Newfoundland (N), Alaska (L), and Hawaii (H).
- Stop pressing when your desired time zone is displayed. The clock will automatically adjust the time.
4. Setting 12/24-Hour Format and Temperature Unit
These settings are typically adjusted using dedicated buttons or a combination of buttons on the back of the clock.
- Tidsformat: Look for a button labeled "12/24H" or similar. Press it to toggle between 12-hour (with AM/PM indicator) and 24-hour formats.
- Temperaturenhed: Look for a button labeled "°C/°F" or similar. Press it to switch the indoor temperature display between Celsius and Fahrenheit.
Betjeningsvejledning
1. Using the Backlight
- The clock features a push-button backlight for temporary illumination.
- Press the large button located on the top of the clock (often labeled "SNOOZE/LIGHT").

2. Indstilling og brug af alarmen
Sådan indstilles alarmtidspunktet:
- Locate the "ALARM SET" button on the back of the clock. Press and hold it until the alarm time begins to flash.
- Use the "+" and "-" buttons (or similar adjustment buttons) to set the desired alarm hour.
- Press "ALARM SET" again to confirm the hour and move to setting the minutes.
- Use the "+" and "-" buttons to set the desired alarm minutes.
- Press "ALARM SET" one last time to confirm and exit alarm setting mode.
For at aktivere/deaktivere alarmen:
- Locate the "ALARM ON/OFF" switch or button, typically on the side or back of the clock (refer to Figure 2).

- Remove the old AAA batteries and dispose of them properly according to local regulations.
- Isæt to nye AAA-batterier, og sørg for at polariteten vender korrekt.
- Close the battery compartment. The clock will restart the atomic synchronization process.
Rensning
- Tør uret af med en blød, tør klud.
- Do not use abrasive cleaners, solvents, or chemical sprays, as these may damage the casing eller display.
