FAQs

How do you set the time and date on the watch?

In the Timekeeping Mode, press A to start setting, then use C to cycle through seconds, hour, minutes, day, month, and year. While digits flash, press B to change values and press D to switch between 12-hour and 24-hour formats. Press A to return after setting.

What is Flash Alert and how can it be enabled or disabled?

Flash Alert causes the backlight to flash while the alarm, countdown timer alarm, or hourly time signal is sounding. In the Timekeeping Mode, hold down B for about two seconds to toggle Flash Alert enabled/disabled, and an indicator shows when it is enabled.

How does the backlight behave and what affects battery life?

Pressing D illuminates the display, and illumination turns off about two seconds after releasing D. Frequent backlight use shortens battery life, and audible sounds may occur when the display is illuminated.
