Setting the Time

This shield provides an RTC function for time information. With the built-in battery mounted on the shield, it maintains the time information even when the power is turned off.

Because of the built-in battery charging system, the battery is charged whenever the power is connected to the shield. However, if you do not connect power to shield for a long period (about 30 days in full-charged), the battery is discharged and time information may be initialized.

  2. Move to the SETUP page.


  3. Click the [TIME SYNC.] on the [TIME] tap.
