2. Nastavenie
2.1 Počiatočné nabíjanie
As an Eco-Drive watch, your AT8300-58E is powered by light. Upon first use or after prolonged storage in darkness, the watch may require an initial charge. Place the watch in direct sunlight or under strong artificial light for several hours. The second hand will move in two-second intervals when the charge is low, indicating the need for charging.
2.2 Príjem časového signálu
The watch automatically attempts to receive time calibration signals daily, typically overnight. For optimal reception, place the watch near a window, away from electronic devices that may cause interference. Ensure the watch face is oriented towards the transmitting station if possible (refer to the full manual for specific regional signal information).
2.3 Nastavenie časového pásma
To ensure accurate time display and proper radio control synchronization, you must set your local time zone. This is typically done by rotating the crown or using specific pushers to select your city code. Consult the detailed instructions in the comprehensive user manual for the exact procedure for your model.

3. Obsluha hodiniek
3.1 Basic Timekeeping and Calendar
Your watch displays the current hour, minute, and second. The day and date are also indicated on the dial. These are automatically adjusted via radio control once the time zone is set and a signal is received.
3.2 Funkcia chronografu
The chronograph allows you to measure elapsed time. Typically, one pusher starts and stops the measurement, while another resets the chronograph hands to zero. Refer to the full manual for specific pusher assignments and operation sequences.
3.3 Funkcia svetového času
To use the world time function, select the desired city code using the crown or pushers. The watch will then display the current time in that specific time zone. This feature is ideal for travelers.
3.4 Svetelný displej
The hands and hour markers on your AT8300-58E are coated with a luminous material. After exposure to light, these elements will glow in the dark, providing readability in low-light conditions.

4. Údržba
4.1 Pokyny pre nabíjanie
To ensure continuous operation, regularly expose your Eco-Drive watch to light. Avoid storing the watch in dark places for extended periods, as this can deplete its power reserve. A full charge can last for several months in darkness, but frequent exposure to light is recommended.
4.2 Čistenie hodiniek
Wipe the watch case and bracelet with a soft, dry cloth to remove dust and fingerprints. For more thorough cleaning, use a slightly damp cloth with mild soap, then rinse with clean water (if water resistance allows) and dry thoroughly. Avoid harsh chemicals or abrasive materials.
4.3 Bezpečnostné opatrenia týkajúce sa odolnosti voči vode
The AT8300-58E is water resistant to 20 bar (200 meters). This makes it suitable for swimming, snorkeling, and diving. Always ensure the crown is fully pushed in before the watch comes into contact with water. Do not operate the pushers or crown while the watch is wet or submerged, as this can compromise its water resistance.
5. Riešenie problémov
5.1 Watch Not Running or Losing Time
- Nedostatočný nabitý: If the watch stops or the second hand moves in two-second intervals, it indicates a low power reserve. Expose the watch to strong light for several hours to fully charge it.
- No Time Signal Reception: If the time is incorrect, the watch might not have received the time calibration signal. Try placing the watch near a window overnight, away from electronic interference.
5.2 Nesprávny čas alebo dátum
- Nastavenie časového pásma: Verify that the correct home city/time zone is set on the watch. An incorrect setting will result in inaccurate time display.
- Manuálne nastavenie: If automatic reception fails, you may need to manually set the time and date. Refer to the comprehensive manual for detailed instructions on manual adjustment.
5.3 Ručičky chronografu sa nevynulujú
If the chronograph hands do not return to their zero position after resetting, a chronograph zero-position correction may be required. This procedure typically involves pulling out the crown and using the pushers to align the hands. Consult the full user manual for the precise steps.
