The time and date can be set either via the relay fascia using appropriate commands in the SYSTEM CONFIG
menu or using the Reydisp software. When the relay is de-energized, the CR1632, 3 V 140 mAh Li/MnO
cell batteries maintains the time and date.
The relay can be synchronized to the nearest second or minute using the Reydisp software. The device can
have a drift of ± 6 s/day.

The default date is set as 01/01/2014 to indicate that the date is not set. In the relay, only the hours and
minutes can be edited. When you press ENTER after editing the seconds, seconds are set to zero and the clock
starts.
By default, the clock follows a 24 hour format for time and DD/MM/YYYY format for date.
