147 + Place the robot in a position as close to neutral as possible, hold the "A" button, and turn it on. Your robot should go to and hold the neutral position, and should
148 + resemble figures 4-1 through 4-3. If the joints are off by more than 15° you may have made an error in assembly. To correct this, remove the
149 + center screw from the round servo horn, pull the servo horn off the servo, rotate until it's aligned, then reattach the servo horn</font><font face="Verdana" size="2">.</font>

162 + is lifted off the ground. This is normal, and is due to the lower power servo. When the robot is walking, the effects are minimal. Using a
163 + voltage that is higher than 6vdc will make the oscillations worse. When building a robot with more powerful servos such as HS-475,
164 + HS-485, or HS-645, you
