Product Overview
This section provides a visual guide to the DreamSky B3 Digital Alarm Clock and its main components.

The image displays the front of the DreamSky B3 Digital Alarm Clock, highlighting its 4.3-inch LCD screen with blue digits. It shows the current time (10:08 AM), temperature (80°F), and date (3-28). Icons above the clock indicate features such as clock, alarm, calendar, dual USB port, USA time zone, auto DST, and temperature. Dimensions are also shown: 5.8 inches wide, 3.1 inches high, and 1.8 inches deep.

The back of the DreamSky B3 Digital Alarm Clock features control buttons for 'TIME SET', '+', '-', 'ALARM ON/OFF', and 'DATE'. A 'LOW DIMMER' to 'HIGH DIMMER' slider is visible on the left side. Two USB ports are clearly labeled 'USB1' and 'USB2', designed for powering the clock and charging other devices.
Setup
Initial Power-On
Connect the provided power adapter to the clock and plug it into a wall outlet. The clock will automatically set itself to the correct year, month, date, and time for the default time zone.
Setting Time Zone
After initial power-on, press the 'TIME SET' button repeatedly to cycle through the available USA time zones (EST, CST, MST, PST) until your local time zone is displayed. The clock will automatically adjust the time accordingly.
Automatic Daylight Saving Time (DST)
The clock automatically adjusts for Daylight Saving Time. To enable or disable this feature, locate the 'DST' setting (usually accessed via the 'TIME SET' button or a dedicated switch, refer to the physical clock for exact location if not on the main buttons) and toggle it On or Off based on your preference.
Operating Instructions
Adjusting Display Brightness
The clock features a 0%-100% adjustable dimmer. Use the 'LOW DIMMER' to 'HIGH DIMMER' slider located on the side of the clock to set the display brightness to a comfortable level. This allows for clear visibility during the day and a subdued display at night.

Maintenance
Cleaning
To clean the clock, use a soft, dry cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these may damage the display or casing.
Battery Backup
The clock includes a CR2032 button cell battery (included) for backup. This battery retains your time, date, and alarm settings during a main power outage. Note that the display will not be active, and the alarm will not sound during a power outage when running on battery backup alone.
Troubleshooting

Alarm not sounding
- Ensure the alarm is activated by pressing the 'ALARM ON/OFF' button. The alarm icon should be visible on the display.
- Check that the alarm time is correctly set.
