Key Components:

• LCD Display: Shows time, date, day of the week, indoor temperature, and outdoor temperature.
• Projection Arm: Projects the time onto a surface.
• Alarm Button: Activates and sets the alarm.
• Calendar Button: Accesses date and calendar settings.
• Snooze/Light Button: Temporarily silences the alarm and activates backlight.
• Power Input: For the included AC adapter.
• Battery Compartment: For backup batteries (3 AAA, not included).

Setup

1. Powering the Clock

1. Insert 3 new AAA batteries (not included) into the battery compartment on the back of the clock. Ensure correct polarity (+/-). These batteries provide backup power during outages.
2. Connect the included power adapter to the clock's power input jack and then plug it into a standard electrical outlet. The LCD display will illuminate.

2. Initial Time Synchronization (Atomic Time)

Upon initial power-up, the clock will automatically attempt to synchronize with the WWVB atomic time signal. This process may take several minutes to several hours, depending on your location and signal strength. Look for the atomic signal icon on the display to confirm successful synchronization.

• For best reception, place the clock near a window, away from electronic devices that may cause interference.
• If the signal is not received, the time can be set manually (refer to the "Operating Instructions" section).

3. Remote Temperature Sensor Setup

1. Install 2 fresh AAA batteries (not included) into the remote temperature sensor.
2. Place the remote sensor outdoors in a shaded, dry location, protected from direct sunlight and precipitation. Ensure it is within range of the main clock unit (typically up to 300 feet line of sight).
3. The main clock unit should automatically detect and display the outdoor temperature. If not, press and hold the "CHANNEL" button (if available, or a similar button) on the main unit to initiate a search for the sensor.

4. Projection Setup

• Adjust the projection arm to point towards your desired surface (wall or ceiling).
• Rotate the focus ring on the projection lens to sharpen the projected image.
• The projection can be rotated 180 degrees by pressing the projection rotation button (if available, or by physically rotating the lens).

Operating Instructions

1. Setting Time and Date Manually

If atomic time synchronization is not desired or unavailable:

1. Press and hold the "CALENDAR" button for 3 seconds to enter time setting mode.
2. Use the "+" or "-" buttons (often shared with other functions) to adjust the flashing value (e.g., hour, minute, year, month, day).
3. Press "CALENDAR" again to confirm the setting and move to the next value.
4. Repeat until all settings are complete.

2. Setting the Alarm

1. Press and hold the "ALARM" button for 3 seconds. The alarm time will flash.
2. Use the "+" or "-" buttons to adjust the hour.
3. Press "ALARM" to confirm the hour and move to minutes.
4. Use the "+" or "-" buttons to adjust the minutes.
5. Press "ALARM" to confirm and exit alarm setting mode.
6. To activate/deactivate the alarm, press the "ALARM" button once. An alarm icon will appear/disappear on the display.

3. Snooze and Backlight Function

• When the alarm sounds, press the "SNOOZE | LIGHT" button to activate the snooze function. The alarm will sound again after approximately 10 minutes.
• Pressing the "SNOOZE | LIGHT" button at any other time will illuminate the display backlight for a few seconds.
• To stop the alarm completely, press any other button (e.g., "ALARM" or "CALENDAR").

4. Display Brightness (Auto Dim)

The clock features an auto-dim function (indicated by "AUTO DIM" on the display) which adjusts the display brightness based on ambient light conditions. This feature is typically automatic and cannot be manually adjusted.

5. Temperature Display

The clock displays both indoor and outdoor temperatures. The outdoor temperature is received from the remote sensor. You may be able to switch between Celsius and Fahrenheit by pressing a dedicated button (often labeled "C/F" or shared with another function).

Maintenance

• Cleaning: Wipe the clock and sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Battery Replacement: Replace batteries in the main unit (for backup) and the remote sensor annually, or when the low battery indicator appears on the display.
• Placement: Avoid placing the clock in direct sunlight, near heat sources, or in areas with high humidity.
