c) Before the next assembly, you need to check the steerability of the servos.
1) First turn the front wheels right and left; pay attention to the utmost
degree of turning: the wheels should be able to turn to a same degree
towards both sides.
2) Turn the pan servo of the mount part right and left to see if its turning
works normally – turning precisely left to right or vice versa.
3) Turn the tilt servo front to back and see if it is able to turn from precisely
front to back or vice versa.
If any of the three servos fails to meet the condition, disassemble it and adjust
based on Servo Adjustment on Page 14. Please DO follow the instructions to
adjust the servos; or else they may get burnt in subsequent operations!
