Operating Instructions:
1. Read all safety information carefully.
2A. To replace one 3V battery holder B1: remove the battery holder and place the B6 power supply in its
place, with the 3V snap on B6 matching the (+) position on B1 and the (–) position on B6 matching the (–)
position on B1. In projects 60 and 180, you must first swap the locations of B1 and switch S1, or B6 will not
fit properly.
2B. To replace two 3V battery holders B1: remove one battery holder and place the B6 power supply in its
place, with the 6V snap on B6 matching the (+) position on B1 and the (–) position on B6 matching the (–)
position on B1. Remove the other battery holder and replace it with a 3-snap wire or a jumper wire. The B6
power supply cannot be used in SC-300/500/750 projects 103, 262, 276, 318, 622, and 689, and SCL-175
projects 12-14,16, 46-58, 60, 92, 120, and 130-134 (these require two independent voltage sources);
batteries must be used for these. SCL-175 projects 10, 17, and 163 will require an additional 3-snap wire
or jumper wire.
2C. To replace one 4.5V battery holder B3: remove the battery holder and place the B6 power supply in its
place, with the 6V snap on B6 matching the (+) position on B3 and the (–) position on B6 matching the (–)
position on B1. Although the power supply has a higher voltage than the battery holder (6V vs 4.5V), your
circuit performance will not be affected.
2D. To replace 9V battery holder B5: remove the battery holder and connect the B6 power supply with the 6V
snap on B6 to the parts of the circuit that were connected to 5V on B5, and connect the (–) snap on B6 to
the parts of the circuit that were connected to (–) on B5. This requires additional snap wires or jumper wires.
3. Plug the Elenco
®
wall AC adapter into a 120VAC, 60Hz outlet.
4. Plug the 9VDC plug of the AC adapter into the input jack on the B6 power supply. The red light on B6 should
be on, indicating your AC-SNAP is ready for use.
5. When using AC-SNAP with projects that run the motor and fan, the circuit may shut down after 1-3
minutes of continuous use. This is due to thermal protection within the B6 power supply, and will be
indicated by the red light in B6 being dim. Unplug the 9VDC plug from the B6 power supply for a few
minutes and then plug it in again.
6. Circuit performance may vary when compared to using batteries. Contact Elenco
®
if you have any questions.
