If you want to lock a DoseCan, turn the lock inside the DoseCan lid. Turn the arrow in latch towards the locket. Use a coin to turn the latch. When DoseCan is locked, use the magnetic key to open it.
WARNING: Do not lock a DoseCan if you don't have a DoseCan magnetic key. The lock should only be used by healthcare personnel managing DoseCans for users and have access to the magnetic key.
