Step 4: Identify where the trigger is and pull bottom board out.
Use a multimeter to show where the continuity is when the button
is pressed. You will hear a beep when there is continuity.

Step 5: Identify the power button and perform the same continuity
test when the button is pressed.

Step 6: Solder wires to the contacts with continuity for the power
and trigger button. Two wires to each button. Caution: Do Not
strip the other end of the wire yet to avoid accidental contacts.

Step 7: Remove the power and trigger buttons from the camera in
order to feed the wires through.
System Modification : Reassembly
All the modifications to the camera are done. Now it’s time
to reassemble.

Step 8: Place the bottom circuit board back on feeding the wires
from the power button through the hole.
Step 9: Place the other circuit board on top making sure to line up
the holes for the three screws.
Step 10: Connect the ribbon and lock it with the black lever.
Step 11: Place the front cover on making sure to feed the trigger
wires through the top hole. Place all screws back in.

DC voltage cannot be put to the camera directly so
relays must be used.
Connect your power and trigger wires to the C and
NO terminals on the relay.
If a PIC microcontroller is going to be used to drive
the relays, they do not put out enough current to
drive the relay, therefore, a transistor buffer must
be used.
Make sure to put a diode between the coil and the
transistor circuit to protect the coil.
