Disconnecting Power
With the Board of Education Rev C, disconnecting power is easy. If you are using the
Board of Education Rev C, power is disconnected by moving the 3-position switch to
position-0 by pushing it to the left as shown in Figure 1-49.
Disconnecting the BASIC Stamp HomeWork Board’s power is easy too. If you are using
the BASIC Stamp HomeWork Board, disconnect the battery as shown in Figure 1-50.
If you are using a Board of Education Rev B, you will not have a 3-position switch.
Either unplug power supply, or remove the 9 V battery, whichever you are using.

Do not remove the BASIC Stamp module from its socket in the Board of Education!
Every time the BASIC Stamp is removed and re-inserted into the socket on the Board of
Education, you risk damaging it. You do not need to remove it for storage.
