2. Setup

2.1 Battery Installation

The clock operates on two 'AA' batteries (not included). To install the batteries:

1. Locate the battery compartment on the back of the clock.
2. Open the battery compartment cover.
3. Insert two 'AA' batteries, ensuring correct polarity (+/-).
4. Close the battery compartment cover securely.

2.2 Automatic Time Setting (Radio Controlled)

This clock is radio-controlled and automatically synchronizes with the atomic clock signal (WWVB) for precise timekeeping. Upon battery installation, the clock hands will typically move to 12:00 and then begin searching for the signal. This process can take 5 to 20 minutes. For optimal signal reception, place the clock near a window and away from electronic devices that may cause interference. Allow the clock to adjust to the correct time before hanging it.

2.3 Time Zone and Daylight Saving Time (DST) Settings

On the back of the clock, you will find controls for setting your time zone and enabling/disabling Daylight Saving Time. Ensure these are correctly configured for your region.

• Time Zone Select: Use the slider to select your appropriate time zone (e.g., Pacific, Mountain, Central, Eastern).
• DST (Daylight Saving Time) On/Off: If your area observes Daylight Saving Time, set this switch to 'ON'. If not, set it to 'OFF'.
