MARATHON Slim Jumbo Panoramic Atomic Wall Clock

Introduction and Overview

The MARATHON Slim Jumbo Panoramic Atomic Wall Clock is designed for precise timekeeping and environmental monitoring. This self-setting and self-adjusting clock automatically synchronizes to the correct time using radio frequencies broadcast from NIST’s Colorado Atomic Clock, ensuring accuracy within North America. Its large, easy-to-read LCD display provides clear visibility from broad distances, making it suitable for various indoor environments. The clock offers multiple display modes, including time (AM/PM or 24-hour format), date (month, weekday, and date), and indoor temperature (Celsius or Fahrenheit). It also supports eight North American time zones and includes a Daylight Saving Time on/off option for convenience.

Safety Information

• Battery Safety: Use only the specified type and number of batteries. Do not mix old and new batteries, or different types of batteries. Ensure batteries are inserted with correct polarity (+/-). Remove exhausted batteries promptly to prevent leakage and damage. If the clock will not be used for an extended period, remove the batteries.
• Placement: Avoid placing the clock in direct sunlight, near heat sources, or in areas with extreme temperatures or high humidity, as this may affect performance and battery life.
• Cleaning: Use a soft, dry cloth for cleaning. Do not use abrasive cleaners, solvents, or chemical agents, which may damage the display or casing.
• Handling: Handle the clock with care. Avoid dropping or subjecting it to strong impacts, which could damage internal components.

Setup

1. Battery Installation: Locate the battery compartment on the back of the clock. Insert four (4) AA batteries, ensuring correct polarity.
2. Initial Synchronization: Once batteries are inserted, the clock will automatically begin searching for the NIST (National Institute of Standards and Technology) atomic clock radio signal. This signal is broadcast from Fort Collins, Colorado, and is available throughout North America. The synchronization process may take several minutes to several hours, depending on your location and signal strength.
3. Signal Reception: For optimal signal reception, place the clock near a window and away from large metal objects or electronic devices that may cause interference. The clock will attempt to synchronize daily, typically in the early morning hours.
