PRO1 Upper PCB Replacement (Use this procedure for PRO1’s with
serial number 610-005000 thru 610-005074.)
1. Using a Philips screwdriver, remove the four (4) display screws on the
back of the display mounting plate.
2. Disconnect all cables connected to the display PCB (P1558) 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 (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.
4. Remove the six (6) standoffs (P1051) from the display PCB. This may
require the use of a 5/16” nut driver or socket. The display PCB will
separate from the overlay.
5. Install the new display PCB and replace standoffs. If your unit had two
plastic standoffs, these need to be placed back at the bottom of the new
display PCB.
6. Plug the heart rate receiver back into the display PCB. It plugs into the
centermost, 3-pin Molex header.

7. Reinsert the display PCB assembly into the front of the console.
8. Reinstall the two, outer countersunk screws in the back of the plastic
console.
9. Reconnect all cables to the display PCB.
•When looking at the back of the display PCB, the telco cables plug
in along the left edge. The 6-pin plugs into the top plug and the 8-
pin plugs into the bottom plug.
•If your unit has Cardio Key, the cable plugs into the serial port,
which is the 4-pin Molex header lower right corner.
•If your unit has Broadcast Vision, Cardio Theater, etc., the cable
connects to the 8-pin header located at the bottom center of the
display PCB.
10.Place the display assembly back onto the mounting plate and install the
four display screws.
11.The model of machine must be defined. (You must rotate the cranks to
power up the upper display to perform this next procedure.) When the
display lights up, see if “ELLIPTICAL” appears in the top window. If so,
press the UP arrow one time to display “PRO”. Once “PRO” is displayed,
press ENTER to save. If no unit type appears in the top window upon
power up, the display has probably been preset at the factory. To verify
this, hold the SCAN, SELECT, and PAUSE for three seconds until a type
of machine appears, then release. Do not continue to hold keys once
the type of unit appears. If “PRO” appears in the top window, press
ENTER to save and exit, unless the unit is equipped with Cardio Key. If
“PRO” doesn’t appear in the top window, press and hold SELECT and the
UP or DOWN arrow until “PRO” does appears. For units with Cardio Key,
when “PRO” appears, press ENTER sixteen times until the top window
shows either “C-SAFE COMM” or “CARDIO KEY”. If “CARDIO KEY” is
displayed, press ENTER three times to exit the mode. If this screen
shows “C-SAFE COMM”, press the UP or DOWN arrow to display
“CARDIO KEY” in the top window, then press ENTER three times to exit
the mode.
