back of the display mounting plate.

the upper console assembly from the unit. Make sure the cables do not

console (A1537) using a Philips screwdriver. This will free the display

PCB and overlay from the plastic console. Do not touch any

components on the PCB. Touching components could cause static

damage. If the heart rate receiver is still plugged into the display PCB,

unplug it now.

require the use of a 5/16" nut driver or socket. The display PCB will

separate from the overlay.

plastic standoffs, these need to be placed back at the bottom of the new

display PCB.
