SCIFIT SXT7000 Parts list manual

Upper PCB (Display) Replacement (Use this procedure for all SX500’s,
SX1004’s thru serial number 905-005170, SX7000’s thru 911-005227, and
SXT7000’s thru 970-005361.)
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 (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, 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
wireless heart rate PCB is still plugged into the upper PCB, unplug it.
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.
6. Plug the wireless heart rate PCB back into the upper PCB. It plugs into
the centermost, 3-pin Molex header.

7. Reinsert the upper PCB assembly into the front of the console.
8. Reinstall the two (2) outer countersunk screws in the back of the plastic
console.
9. Reconnect all cables to the upper PCB (as shown at the top of this
procedure).
•The contact heart rate PCB has a cable coming up from the neck of
the unit. This plugs into the outermost, 3-pin Molex header next to
the wireless heart rate header.
•When looking at the back of the upper 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
upper PCB.
10.Place the display assembly back onto the mounting plate and install the
four (4) display mounting screws.
11.The model of machine must be defined. (You must rotate the TeleRails or
have the wall pack plugged in 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 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 (3) seconds until a type of machine appears, then
release. Do not continue to hold keys once the type of unit appears.
If “ELLIPTICAL” appears in the top window, press ENTER to save and
exit, unless the unit is equipped with Cardio Key. If “ELLIPTICAL” doesn’t
appear in the top window, press and hold SELECT and the UP or DOWN
arrow until “ELLIPTICAL” does appears. For units with Cardio Key, when
“ELLIPTICAL” 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.
