Key Features

• Atomic Accuracy: Built-in receiver for WWVB broadcast signal from NIST, Fort Collins, Colorado, USA, ensuring precise time synchronization daily.
• Jumbo 4.5" Tall LCD Time Display: Large, easy-to-read display showing time (hours, minutes, seconds), indoor and outdoor temperature, calendar, and day of week. Ideal for visibility from a distance.
• Wireless Outdoor Sensor: Measures accurate indoor/outdoor temperature and humidity in °F or °C. Wireless range up to 328ft (100M) in open areas.
• Battery Powered: Main unit powered by 4 AA batteries, outdoor sensor by 2 AAA batteries (not included). Extended battery life up to 18 months due to efficient chip design.
• Versatile Placement: Can be hung on a wall or placed on a table using the integrated kickstand.

Setup Guide

1. Install Batteries:
   • Open the battery compartment on the back of the main clock unit. Insert 4 new AA batteries, observing polarity (+/-).
   • Open the battery compartment on the wireless outdoor sensor. Insert 2 new AAA batteries, observing polarity (+/-).
   • Ensure both units are powered on within 3 minutes of each other for successful pairing.
2. Sensor Pairing: The outdoor sensor will automatically attempt to pair with the main unit. A signal strength indicator will appear on the clock's display once connected. If pairing fails, press the "CHANNEL" button on the main unit to re-register the channel, or re-insert batteries in both units.
3. Atomic Time Synchronization (WWVB):

   The clock will automatically attempt to receive the WWVB atomic signal from Fort Collins, Colorado. This usually occurs overnight. Place the clock in an area with good reception, away from large metal objects or electronic interference. A tower icon will appear on the display when the signal is successfully received.

   To manually initiate atomic signal reception, press and hold the "DOWN/RCC" button for 3 seconds. The clock will begin searching for the signal.

4. Set Time Zone: Press the "UP/ZONE" button repeatedly to cycle through the available time zones (EST, CST, MST, PST, AKST, HST) until your desired time zone is displayed.
5. Temperature Unit Selection: Press the "DOWN/RCC" button briefly to switch between Fahrenheit (°F) and Celsius (°C) for temperature display.

Operating Instructions

Display Information:

• Time: Large digits display hours, minutes, and seconds. AM/PM indicator is present for 12-hour format.
• Date & Day of Week: Displays month, day, and the full day of the week.
• Indoor Temperature & Humidity: Shown on the left side of the lower display.
• Outdoor Temperature & Humidity: Shown on the right side of the lower display, received from the wireless sensor.
• Atomic Signal Indicator: A tower icon indicates successful reception of the WWVB signal.
• DST Indicator: Displays when Daylight Saving Time is active.
• Battery Low Indicator: An icon will appear in the upper right of the screen when batteries are low.

Button Functions (Rear of Unit):

Note: The clock can display readings from up to 3 outdoor sensors. Use the CHANNEL button to switch between them or enable auto-cycling.

Maintenance

• Battery Replacement: When the low battery indicator appears, replace all batteries in both the main unit and the outdoor sensor. It is recommended to use high-quality, non-leaking batteries (e.g., Lithium batteries) to prevent damage to the device, especially for long-term use.
• Cleaning: Wipe the clock and sensor with a soft, dry cloth. Do not use abrasive cleaners or chemicals, as they may damage the display or casing.
• Sensor Placement: For optimal performance and longevity, place the outdoor sensor in a shaded area that is protected from direct sunlight and heavy rain. While the sensor is splash-proof, prolonged exposure to harsh weather conditions can affect its accuracy and lifespan.

Troubleshooting

No Display or Faint Display:

Check battery polarity and ensure batteries are fresh. Replace all batteries if necessary.

Outdoor Temperature/Humidity Not Displaying or Inaccurate:

• Ensure batteries in the outdoor sensor are fresh and correctly installed.
• Press the "CHANNEL" button on the main unit to re-establish connection or cycle through channels.
• Move the outdoor sensor closer to the main unit to improve signal strength. Avoid large metal objects or thick walls between the units.
• Ensure the sensor is not in direct sunlight, which can cause artificially high temperature readings.

Atomic Time (WWVB) Signal Not Received:

• Place the clock near a window or in an open area, away from electronic devices that may cause interference.
• Manually initiate signal reception by holding the "DOWN/RCC" button for 3 seconds.
• Note that signal reception can be affected by atmospheric conditions, geographical location, and time of day (best reception is often overnight).

Incorrect Date/Day of Week:

Ensure the correct year is set if manually setting the time, as this can affect the calendar function. The atomic signal should correct this automatically once received.
