V. Adjustments and Parts Replacement
A.
Upper PCB Replacement
(Use this procedure for ISO7000R’s with
serial numbers thru 570-005256.)
1. Using a Philips screwdriver, remove the four (4) display mounting screws
on the back of the display mounting plate.
2. Disconnect all cables running to the upper PCB and remove the upper
console assembly from the unit. Make sure the cables do not fall into
the neck of the unit.
3. Remove the two (2) outer countersunk screws in the back of the plastic
console using a Philips screwdriver. This will free the upper PCB and
overlay from the plastic console. Do not touch any components on the
upper PCB. Touching components could cause static damage. If
the heart rate PCB is still plugged into the upper PCB, unplug it now.
4. Remove the six (6) standoffs from the upper PCB. This may require the
use of a 5/16” nut driver or socket. The upper PCB will separate from the
overlay.
5. Install the new upper PCB and replace standoffs. If your unit had two (2)
plastic standoffs, these need to be placed back at the bottom of the new
upper PCB.
