This document provides a comprehensive guide for the 513-21867 clock, designed for weather enthusiasts who value accurate and reliable timekeeping. It covers setup, positioning, troubleshooting, and maintenance, ensuring optimal performance of your device.

Function Description

The 513-21867 is a versatile clock that offers precise timekeeping, including atomic time synchronization, and can display various environmental data. Its core function is to provide accurate time, which can be manually set or automatically synchronized via the WWVB Atomic Time Signal. The clock also features a calendar display with multiple formats, and the ability to show temperature readings, either indoor or from an optional outdoor sensor. A backlight ensures visibility in various lighting conditions. The device is designed to be user-friendly, with clear settings and troubleshooting steps to help users maximize its utility.

Usage Features

Power Requirements and Batteries:

The clock operates on 6 "AA" batteries. For optimal performance, it is recommended to use fresh batteries with an expiration date at least six years in advance of the current year, ensuring a minimum voltage of 1.48V per battery.

Basic Setup:

Insert the 6 "AA" batteries into the clock.
Access the Basic Settings menu to configure the device.

Manual Time Setting:

To manually set the time:

Hold the "Settings" button for 2 seconds to enter settings mode.
Use the "+" or "-" buttons to adjust the flashing values. Holding these buttons allows for quick adjustments.
Press the "Settings" button to confirm adjustments and move to the next item.
Press the "Settings" button at any time to exit the settings menu.

Settings Order:

The settings menu allows configuration of:

Language: English, Spanish, French, or German. This selection impacts weekday readouts and menu items.
Beep Sound: ON/OFF.
Atomic Time: ON/OFF. If set to OFF, DST and Time Zone settings are skipped.
Daylight Saving Time (DST): Options include AUTOMATIC (default, adjusts for DST), ALWAYS OFF (remains in Standard Time), or ALWAYS ON (remains in Daylight Saving Time).
Time Zone: Select your local time zone (e.g., EASTERN).
Time Format: 12-hour or 24-hour.
Hour and Minutes: Manually set the current hour and minutes.
Year, Month, and Date: Manually set the current year, month, and date. The weekday automatically adjusts once these are set.
Date Format: Month/Date or Date/Month.
Temperature Unit: Fahrenheit or Celsius.

Atomic Time (WWVB Signal):

The clock searches for the WWVB Atomic Time Signal upon power-on. If no reception occurs, it will search automatically at UTC 17:00, 18:00, 19:00, 10:00, and 11:00. If still no reception, it searches every 2 hours until the signal is received. The atomic time signal icon flashes during search and becomes solid upon connection. You can manually initiate a search by pressing the "Atomic Time" button from the normal time display.

Reception Notes: The WWVB signal can be received up to 2,000 miles from Boulder, Colorado. However, reception is limited during daylight hours due to the Earth's ionosphere. The clock will search for a signal nightly when reception is best. Allow up to 5 nights for DST changes to occur.
Troubleshooting Loss of WWVB Signal:
1. Check for a Tower Icon on the display, indicating recent reception.
2. Verify the correct Time Zone is set.
3. Ensure ATOMIC is ON.
4. Confirm DST indicator is ON if you expect automatic DST changes.
5. Position the clock with the front or back facing Fort Collins, Colorado, to optimize antenna reception.

Desired Hour (Time Adjust):

This feature allows you to set a "Desired Hour" to match other time zones, while the clock remains accurate via the Atomic Time Signal. Only the hour can be changed.

Setting Desired Hour:
1. Hold the "Desired Hour" button until the hour flashes and "Desired Hour" appears.
2. Use the "+" button to adjust the hour. The "-" button resets to the "current hour."
3. Press the "Desired Hour" button to confirm and exit.
Switching Between Desired and Local Time: Press the "Desired Hour" button to toggle between Desired Time (indicated by an icon) and Local Time.

Calendar Display Options:

Press the "Calendar" button to cycle through display formats:

Full Weekday
Month/Date/Year
Weekday/Month/Date

Backlight:

The clock features a backlight with five intensity levels (OFF, 1, 2, 3, 4). A power cord is required for constant backlight. Press and release the "Backlight" button to adjust intensity or turn it off. Intensity levels are 0% (OFF), 1.5%, 20%, 50%, and 100%.

Time and Temperature Display Selection:

Press the "Display" button to adjust the data shown on screen:

Current Time/Indoor Temp
Current Time/Outdoor Temp
Desired Time/Indoor Temp
Outdoor Temp/Desired Time
Indoor Temp/Desired Time
Auto-Scroll: When the "Auto-scroll" icon is active, the clock cycles through these options every 5 seconds. Press the "Display" button to stop auto-scroll and keep the current selection.

Add-on Sensors:

For outdoor readings, an add-on Temperature & Humidity Sensor can be purchased separately.

Adding a Sensor:
1. Install batteries in the Temperature & Humidity sensor.
2. Hold the "+" button on the clock until the Reception Indicator animates, initiating a search.
3. Press the TX button on the sensor.
4. The sensor should connect within minutes.
Viewing Add-on Sensor Readings: Press the "Display" button to view Add-on Sensor readings, Time, Desired Time, or Indoor Temperature & Humidity.

Maintenance Features

Troubleshooting "HI" or "LO" Readings:

If your outdoor temperature reading shows "HI" or "LO," it indicates that the temperature is outside the sensor's measurable range.

Check that the batteries in the outdoor sensor are good. Overpowered or underpowered batteries can cause this.
If batteries are good, replace the outdoor sensor.
If your temperature is fine but humidity reads "HI," "LO," or dashes, your humidity may be below 10% Relative Humidity, which the sensor does not read.

Troubleshooting "NO" Reading:

If a sensor loses connection to the clock, "NO" will appear after 30 minutes.

The clock searches for 3 minutes every hour to reconnect.
Hold the "+" button to manually search for sensors in the Outdoor Area.
The icon will flash during the search, and the outdoor area will show dashes. It will become solid upon successful reception.
If no sensor is found after 3 minutes, the icon disappears, and "NO" will reappear in the outdoor sensor area.

Factory Reset:

To perform a factory reset:

Remove the power cord and batteries.
Press any button 20 times.
Reinsert the batteries.

This comprehensive guide ensures that users can effectively set up, operate, and troubleshoot their 513-21867 clock, providing a reliable and enjoyable experience for monitoring time and environmental conditions.
