Setup
1. Battery Installation
Locate the battery compartment on the back of the clock. Insert 3 AAA batteries (not included) according to the polarity indicators (+ and -). Ensure the battery compartment cover is securely closed.

2. Initial Power-On and Atomic Signal Reception
Upon battery installation, the clock will automatically attempt to receive the WWVB atomic time signal. This process may take several minutes to several hours, especially during initial setup. For best reception, place the clock near a window and away from electronic devices that may cause interference. The atomic signal is typically stronger at night.

A signal strength indicator (often a tower icon with waves) will appear on the display once a successful signal is received. If the signal is not received immediately, the clock will default to a manual time setting. You can manually initiate a signal search by holding the "WAVE" button (if present) on the back of the clock for a few seconds.
Operating Instructions
1. Manual Time and Date Setting
In case the atomic signal is not available or for manual adjustment:
- Press and hold the SET button (or similar, refer to back panel buttons) for a few seconds until the display flashes.
- Use the UP and DOWN buttons to adjust the flashing value (e.g., hour, minute, year, month, day).
- Press SET again to confirm the selection and move to the next setting.
- Repeat until all desired settings are configured.
2. Alarm Settings
The clock features two independent alarms (ALM 1 and ALM 2).
- Press the ALARM button (or ALM 1/ALM 2 button) to select the alarm you wish to set.
- Press and hold the ALARM SET button (or similar) until the alarm time flashes.
- Use the UP and DOWN buttons to adjust the alarm hour and minute.
- Press ALARM SET to confirm.
- To activate/deactivate an alarm, press the corresponding ALARM ON/OFF button. An alarm icon will appear on the display when active.
3. Temperature Display
The clock displays indoor temperature. To switch between Fahrenheit (°F) and Celsius (°C), locate the °F/°C button on the back of the unit and press it.

Maintenance
Cleaning
Wipe the clock with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the display or casing.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock not setting automatically. | Weak or no atomic signal reception. Interference from other electronics. Incorrect time zone setting. | Relocate the clock closer to a window, away from electronic devices (TVs, computers, microwaves). Try initiating a manual signal search (WAVE button). Ensure correct time zone is set if applicable. Note that the signal is often stronger at night. |
| Display is dim or blank. | Low batteries. | Replace all AAA batteries with new ones. |
| Time is incorrect after Daylight Saving Time change. | Atomic clock may take up to 24 hours to adjust or requires manual adjustment for DST. | Allow up to 24 hours for automatic adjustment. If it doesn't adjust, manually set the time. Some atomic clocks may not automatically adjust for DST and require manual intervention. |
| Alarm not sounding. | Alarm not activated. Alarm volume too low (if adjustable). | Ensure the alarm icon is visible on the display. Check alarm settings and ensure the time is correctly set. |
