If needed, strip 1/8" of insulation off of each end.
Tin the buzzer with solder in the locations shown in Figure 6-3a.
Tin both ends of the three 2" wires as shown in Figure 6-3b.
Carefully solder the three 2" wires onto the buzzer as shown in Figure 6-3.
Thread the three wires through the buzzer pad and then through the hole from the solder side of the PC
board as shown in Figure 6-3.
Solder the three wires to the PC board as shown in the
Figure 6-3. The gray wire goes to B1, the orange wire goes
