± ; or, it uses Time Base of RTC DS3231 internal Clock instead. The Clock always chooses Time Base from GPS automatically 
after Power-ON if it is connected. 

 

Clock receives all user’s Commands via IR Remote (provided with device) 

 

IR Remote uses Battery 3V #CR2025 (included in set); and Clock uses Battery Backup 3V #CR2032 (included in set)

external devices. 

 

If using Time Base from GPS, it always auto updates Date/Time of RTC (DS3231) internal Clock after Power-ON. Or, if using 
Time Base from RTC (DS3231) internal device, user can manually setup Time/Date by IR-Remote.
