Setup Guide

1. Battery Installation

The Franklin CL-1 clock requires 4 AA-size batteries (not included) for operation.

1. Locate the battery compartment on the back of the clock.
2. Open the battery compartment cover.
3. Insert 4 new AA batteries, ensuring correct polarity (+ and -) as indicated inside the compartment.
4. Close the battery compartment cover securely.

2. Initial Power On and Signal Reception

Upon battery installation, the clock will automatically begin searching for the WWVB atomic time signal. This process may take several minutes to several hours, depending on your location and environmental conditions.

• Optimal Placement: For best reception, place the clock near a window, away from large metal objects, electronic devices, and sources of electromagnetic interference.
• Signal Strength: The WWVB signal is typically stronger during nighttime hours. If initial setup fails, try placing the clock in a different location or allow it to attempt synchronization overnight.
• Time Zone Selection: Once the signal is received, you may need to manually select your time zone. Refer to the "Operating Instructions" section for details.

Operating Instructions

1. Automatic Time Synchronization (WWVB)

The clock is designed to automatically receive the WWVB atomic time signal from Fort Collins, Colorado, ensuring accurate timekeeping. The signal covers the entire continental United States.

• The clock will attempt to synchronize daily, typically in the early morning hours.
• A signal icon on the display indicates successful reception.

2. Manual Time and Time Zone Setting

If automatic synchronization is not desired or unavailable, you can manually set the time and time zone.

1. Refer to the buttons on the back of the clock (e.g., SET, MODE, UP, DOWN).
2. Press the MODE button to cycle through settings (Time, Date, Alarm, Time Zone).
3. When the desired setting is blinking, use the UP or DOWN buttons to adjust the value.
4. Press SET or MODE again to confirm and move to the next setting.
5. Available Time Zones: Atlantic, Eastern, Central, Mountain, Pacific, Alaskan, Hawaii.

3. Daylight Saving Time (DST)

The clock automatically adjusts for Daylight Saving Time. No manual intervention is typically required if atomic synchronization is active.

4. Temperature and Humidity Display

The clock displays indoor temperature and humidity. You can select the temperature unit.

• Temperature Range: 14.1°F to 122°F (-9.9°C to 50°C).
• Humidity Range: 20% to 99%.
• To switch between Fahrenheit (°F) and Celsius (°C), locate the F/C button (often combined with another setting button) on the back of the clock and press it.

5. Seconds Hand Display On/Off

The digital seconds hand can be turned off to simplify the display and potentially improve readability for some users.

• Consult the specific button (e.g., "SECONDS" or "DISPLAY") on the back of the clock to toggle this feature.

6. Daily Alarm Feature

The clock includes an optional daily alarm.

1. Press the MODE button until the alarm time is displayed or blinking.
2. Use the UP or DOWN buttons to set the desired alarm time.
3. Press SET or MODE to activate/deactivate the alarm and confirm.

Mounting Options
