Setup

The watch comes with one CR2032 battery pre-installed. This battery is designed to power the watch for over one year, eliminating the need for frequent charging. When the battery needs replacement, use a standard CR2032 coin cell battery.
2. Automatic Time Setting (Atomic Clock Synchronization)
The Hearkent Atomic Talking Watch automatically sets itself by receiving signals from the official U.S. atomic clock. It also adjusts for daylight saving time automatically. For initial setup, ensure the watch is in an area with good signal reception.
3. Setting Your Time Zone
Before the watch can display the correct local time, you must set your specific time zone. Refer to the detailed instructions provided in your physical manual for the precise steps to adjust the time zone. This is a critical step for accurate time display and announcements.

Maintenance
1. Cleaning Your Watch
To clean your watch, gently wipe the display and strap with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials, as these can damage the watch's finish or electronic components. Ensure the watch is dry before wearing it again.
2. Battery Replacement
When the watch's voice becomes faint or the display dims, it may be time to replace the CR2032 battery. To replace the battery, carefully open the watch back using a small screwdriver or watch tool. Remove the old battery and insert a new CR2032 battery, ensuring correct polarity. Close the watch back securely.
3. Strap Care
The watch features a soft PU (polyurethane) strap. To maintain its condition, avoid prolonged exposure to direct sunlight, extreme temperatures, and harsh chemicals. Clean the strap with a damp cloth as needed.
Troubleshooting
- Watch Not Setting Automatically: Ensure the watch is in an open area away from strong electronic interference. Atomic clock signals can be affected by location, building materials, and weather conditions. Try placing the watch near a window overnight. Verify that the correct time zone is selected.
- No Voice Announcement or Faint Voice: Check the battery level. A low battery can affect voice clarity and volume. Replace the CR2032 battery if necessary. Ensure the volume setting (if adjustable, refer to your physical manual) is not set to minimum.
- Incorrect Time or Date Display: If the watch is not synchronizing with the atomic clock, manually set the time and date as a temporary measure. Re-verify your time zone setting.
- Buttons Not Responding: Ensure the watch is not in a locked mode (if applicable, refer to your physical manual). If the issue persists, a battery replacement might resolve it.
