you must carefully pry this connector loose and lift
the digital board away from the camera. Care should
be taken not to pull too strongly on the digital board
far from the connector as this could bend the board
and cause cracks in the delicate traces.
Once the digital board is removed locate the jumper
pins just next to the row of five LEDs that show
through holes in the side of the camera body. The
jumper pins are immediately adjacent to LED02 (see
photo below). There are four pairs of pins. Jumpers
must be placed on the two pairs of pins farthest away
from the LEDs (bottom photo below).
Factory configuration: No jumpers. Jumpers set for Relay Box
Replace the digital board taking care to align all the pins in the connector before applying slight
pressure to seat the pins. Replace the five Phipllips-head screws and plug in the fan wiring
harness. Then replace the back plate.
