Setup
Setting Time and Date
Setting the time and date on your digital watch requires careful attention to the button presses. While specific instructions may vary slightly by model revision, the general procedure involves entering a "set" mode and adjusting values.
- Locate the "MODE" button (typically on the left side). Press it repeatedly until you reach the Time Setting mode, often indicated by flashing digits.
- Use the "ADJ" (Adjust) or "SET" button (often on the left side) to select the digit you wish to change (e.g., hours, minutes, year, month, day).
- Use the "STOP/START" or "EL" (Electroluminescent) button (typically on the right side) to increment the selected digit. Hold the button to advance rapidly.
- Once all settings are correct, press the "MODE" button again to exit the setting mode and save your changes.
Note: If you encounter difficulty, refer to the official Armitron support resources or online tutorials for your specific model.
