This document describes a splash-proof atomic clock with outdoor temperature and humidity display, designed for outdoor use. The clock, model 515-1912, comes with a remote sensor (TX191TH) and offers various features for timekeeping and environmental monitoring.
The primary function of this device is to provide accurate timekeeping through its atomic clock feature and to display both indoor and outdoor temperature and humidity. The atomic clock automatically synchronizes with the WWVB Atomic Time Signal, ensuring precise time without manual adjustment. It also includes a timer function for various timing needs. The splash-proof design makes it suitable for outdoor environments, providing reliable performance in different weather conditions.
To begin using the clock, two AA batteries must be inserted into the outdoor sensor and two AA batteries into the atomic clock itself. After battery installation, basic settings need to be configured. Once the sensor establishes a connection with the clock, it should be placed outdoors in a shaded location for accurate readings. A video on sensor mounting is available for guidance.
The clock features several buttons for easy navigation and setting adjustments:
The clock automatically searches for the WWVB Atomic Time Signal at specific UTC times (7:00, 8:00, 9:00, 10:00, and 11:00). During the search, the Atomic Time Indicator will flash; once connected, it will remain solid. Users can manually initiate a search for the atomic time signal by pressing the SET button from the normal time display.
The settings menu allows users to customize various aspects of the clock:
The MINUS (-) button allows users to cycle through different display views:
The clock includes a versatile timer:
If the outdoor sensor loses connection with the clock, "NO" will be displayed after 30 minutes. The clock will automatically search for the sensor for 3 minutes every hour to re-establish connection. To manually search for the outdoor sensor, hold the PLUS (+) button until the Reception Icon begins to flash.
The clock provides low battery indicators for both the main unit and the outdoor sensor. A low battery icon next to the time indicates that the clock's batteries need replacement. A low battery icon next to the outdoor temperature indicates that the sensor's batteries need replacement.
To ensure the longevity and optimal performance of the device, users should adhere to the following guidelines:
