Note: Before you remove Holder/Battery 3, be sure that CompactFlash card release lever is in upright position. 11. Take Knob/Selector 6 and PCB Ass’y/Key 5 off the case. Note: Knob/Selector 6 can be removed by unscrewing two screws f from the bottom of the knob. 12.Peel Grip K then remove one screw h from Panel/Rear J. Unclip the E-ring from Pin J.
14.Lift up the stopper tab of connector CN700 and disconnect FPC cable. Also disconnect connector CN920. 15.Remove the BRIGHT knob T and take PCB Ass’y/Linear off the case. Note: Be careful not to bend or break the LED on the other side of the PCB. 16.Remove Three screws l from BL ass’y _ then remove the BL ass’y. Note: Do not touch BL ass’y with naked hand. 17.Remove Spacer ] and Display Ass’y [. Note: Do not touch Display Ass’y with naked hand. Camera Unit 18.Remove three screws h and m.
19.Peel off the caution label. Caution: Since high-voltage is applied on the circuits on Camera Unit, there is a risk of electric shock. Before proceeding to the following steps, discharge 70 µF, 300 V capacitor with a 1.5 kohm,5 W cement resistor. 1.5 kohm/5W resistor 20.Remove two screws and disconnect two wires red and white. 21.Remove Strobe unit 1-3 . 22.Remove two screws from the gear.
