If the current pay period ending date is on the back side of 
the time card, after the calculation has been taken for the 
last day of the pay period, the clock will display “FLIP” for 
up to 20 seconds. This will allow you to ip your time card 
around and re-insert the time card back into the clock to 
have the summary for the pay period printed on the time 
card.
After the last day of the pay period, the time clock will 
clear the stored information for the pay period.
