Isgus Perfect 2040 Operating Manual page 59

Hint
If the PERFECT serves as master clock and if the recorder is
provided with an battery pack, a synchronization between master
clock and slave clocks takes place in the following situations:
· Daylight saving time
· Manually setting the time at the master clock
· Power failure
If the PERFECT serves as master clock and if the recorder is not
provided with an battery pack, no synchronization between
master clock and slave clocks takes place in case of power
failure. After restart of mains operation, the synchronization is
however continued again automatically until the slave clocks
have reached the current time.
If you have any questions, please contact your local dealer
where you have purchased the time recorder or e-mail us at:
