Press the START / STOP (MEMORY) key 6 to open the most
recently selected times for all three timers.
Press the START / STOP (MEMORY) key again to start all

Q
Changing the batteries
Note: If the legibility of the 1 decreases due to diminishing
contrast, then the inserted batteries are discharged and must be
replaced.
Open the battery compartment cover 14 on the rear side of
the device by pushing it outwards in the direction of the arrow.
Remove the old batteries. Use a thin, pointed object to lever
the batteries out of the battery compartment.
Note: Make sure you insert the batteries the right way round
(polarity). This is shown above the battery compartment.
Close the battery compartment cover again, so that it engages
audibly.
