Your kit contains a miniature DPDT switch. Some versions require installation
of a plastic clip-on support at the front of the switch body. This piece relieves

Locate the 9-V battery snap clip, and note the red+ lead and black- lead.
# # 19.$Install the red lead at BAT1 (+) and solder.
# # 20.$Install the black lead at BAT1 (-) and solder.
Find the oversized hole slightly to the rear of the BAT1 connections. The plastic
tie-wrap supplied with your kit will be installed here to bind the two battery
leads to the PC board. This will help prevent lead breakage later on.
