(b)  
Do the continuity check between the pins shown in step 1, Fig. 204, for each switch and do these adjustments as necessary. 1) If an open circuit exists, push the locking channel on the

 microswitch pack and turn the adjustment bolt counterclockwise just until a closed circuit exists. Continue to turn the adjustment bolt counterclockwise the minimum amount necessary to lock the bolt in the channel.
 2)  If a closed circuit exists, continue with the procedure.
 (c)  
Set the left and right autothrottle cams to the postion shown in step 2, Fig. 204, for each switch.

 (d)  
Do the continuity check between the pins shown in step 2, Fig. 204, for each switch and do these adjustments as necessary. 1) If an open circuit exists, push the locking channel on the

 microswitch pack and turn the adjustment bolt counterclockwise until a closed circuit exists. Then turn the adjustment bolt clockwise just until an open circuit exists. Continue to turn the adjustment bolt clockwise the minimum amount necessary to lock the bolt in the channel.
 2)  If a closed circuit exists, push the locking channel on the microswitch pack and turn the adjustment bolt clockwise just until an open circuit exists. Continue to turn the adjustment bolt clockwise the minimum amount necessary to lock the bolt in the channel.

 (8)  Do these steps to adjust switches S10, S14, S17 and S18.
 NOTE: Switches S10, S14, S17, and S18 must be adjusted in the
____
 sequence shown.

 NOTE: Switches S10/S17 and S14/S18 are mechanically paired
____ together, use a common adjusting bolt (see Fig. 202).
 NOTE: Switches S10/S14 are electrically paired together and must be
____
 adjusted in the sequence shown (see Fig. 203).

 (a) Step 1: 1) Set the left and right autothrottle cam's to the position shown in step 1, Fig. 204, for switches S17 and S18. 2) Do a continuity check between the pins shown in step 1, Fig. 204, for switches S17, S18 and do these adjustments as necessary. a) If a open circuit exists, push the locking channel on the microswitch pack and turn the adjustment bolt counterclockwise just until a closed circuit exists. Continue to turn the adjustment bolt counterclockwise the minimum amount necessary to lock the bolt in the channel. b) If a closed circuit exists, continue with the procedure. 3) Do a continuity check between the pins shown in step 1, Fig. 204, for switches S10, S14 and do these adjustments as necessary. a) If an open circuit exists, push the locking channel on the microswitch pack and turn the S10 sdjustment bolt one turn then turn the S14 adjustment bolt one turn in the counterclockwise direction. Continue this sequence just until a closed circuit exists. Continue to turn the adjustment bolt counterclockwise the minimum amount necessary to lock the bolt in the channel.
 b)  If a closed circuit exists for both switches, go to step 2.
 (b) Step 2: 1) Set the left and right autothrottle cam's to the position shown in step 2, Fig. 204, for switch S10. 2) Do a continuity check between the pins shown in step 2, Fig. 204, for switch S10 and do these adjustments as necessary. a) If a closed circuit exists, push the locking channel on
 the microswitch pack and turn the adjustment bolt counterclockwise until an open circuit exists. The turn the adjustment bolt clockwise just until a closed circuit exists. Continue to turn the adjustment bolt clockwise the minimum amount necessary to lock the bolt in the channel.
