The Zgrmbo Night Light Atomic Clock (Model ZG3566A) is a versatile digital clock designed for various indoor settings such as bedrooms, desks, and travel. It features an accurate atomic time calibration, automatic daylight saving time adjustment, and a built-in ambient light sensor for auto-dimming. Additionally, it provides indoor temperature and humidity readings, and offers dual alarm settings with a customizable snooze function.

2. Opsætning og første brug
2.1 Batteriinstallation
The clock is powered by 2 AAA batteries (not supplied). To install:
- Åbn batterirummets dæksel på bagsiden af uret.
- Isæt to nye AAA-batterier, og sørg for at polerne vender korrekt (+/-).
- Luk batterirummets dæksel forsvarligt.

2.2 Atomic Time Synchronization
After battery installation, the clock will automatically attempt to retrieve the WWVB time calibration signal sent by NIST. This process ensures accurate time to the second and automatically adjusts for Daylight Saving Time (DST).
- The clock will search for WWVB time airwave signals at 1:00 AM, 2:00 AM, and 3:00 AM each day to correct the time.
- To ensure better reception, place the clock in an area with a good signal, such as near a window.
- The clock supports 7 time zones: AST, EST, CST, MST, PST, AKT, HAT. Ensure you select the correct time zone before the clock calibrates.

3. Betjening af uret
3.1 Time Display & Format
The large LCD display shows the current time, date, day of the week, indoor temperature, and humidity. The time can be displayed in either 12-hour or 24-hour format.
3.2 Auto-Dimming & Night Light
The clock features a built-in ambient light sensor. In dark environments, it automatically triggers a soft night light to illuminate the display. You can manually control this feature:
- Langt tryk the top of the clock to turn the auto-dimming mode ON/OFF.
- Kort tryk the top of the clock to manually light up the clock display.

3.3 Alarm Clock with Snooze

- Set two distinct alarms for different needs (e.g., weekday and weekend).
- The snooze duration can be set from 5 to 60 minutes.

3.4 Temperature & Humidity Monitor
Keep track of your indoor environment with the integrated temperature and humidity sensors.
- Temperature range: 14℉ to 122℉ (-9.9℃ to 50℃).
- Humidity range: 20%RH to 95%RH.

6. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Clock not displaying time/powering on. | Batterierne er døde eller isat forkert. | Udskift batterierne med nye AAA-batterier, og sørg for at polariteten vender korrekt. |
| Atomtiden synkroniserer ikke. | Weak WWVB signal. | Move the clock closer to a window or to a different location with better signal reception. Allow several hours for synchronization. |
| Time resets randomly. | Interference or weak signal causing reset. | Ensure the clock is not near electronic devices that may cause interference. Try relocating the clock. |
| Skærmen er for svag eller for lys. | Auto-dimming setting or manual override. | Long press the top button to toggle auto-dimming. Short press to manually adjust brightness. |
