The jumper caps are small black plastic sleeves, open at two ends. Spare caps are
provided. They are stuck on one of the jumpers’ pins.
To remove a cap, pull straight up. To attach a cap, push straight down onto the two jumper
pins. Both ends of the cap are the same, so it does not matter which way you attach it.
Hint: A cap is “attached” when it straddles both pins. It is “removed” when it is on no pins
or on only one pin. Therefore, a handy way of storing a spare cap is to stick it on only one
jumper pin.
