-The first two commands should move pan servo back and forth.  The last two commands should move the tilt servo up and down.  Are the servos reversed?  If so, reverse the servo connectors.  Is the movement smooth and rapid?  If not, make a note of which servo is acting strange, and send us an email describing your experience (<[email protected]>).
+The first two commands should move pan servo back and forth.  The last two commands should move the tilt servo up and down.  Are the servos reversed?  If so, reverse the servo connectors.  Is the movement smooth and rapid?  If not, try removing one of the servos and measuring the voltage at the exposed servo connector with a voltmeter while exerting torque on the other servo.  Refer to the picture below for the servo connector pin-outs.
+{{wiki:v2:image_248_2.jpg?500}}
+The measured voltage should be 4.9V or above with the other servo under load.  If the voltage is less than 4.9V investigate your power source's ability to deliver at least 500mA.
+Regardless, send us an email describing your experience (<[email protected]>).
