GENERAL TROUBLESHOOTING TOC
•UPDATE TO THE LATEST SOFTWARE VERSION, if possible.
oReference the Software Update topic if anything unexpected happens.
•Cycling power is recommended as the first attempt to fix most failures, and after major repairs are
implemented.
•If multiple, identical machines are available, swap suspected failed parts (console, cables, etc.)
and observe if the failure follows.
•If unsure where to begin with degraded console performance, disconnect everything from the
UCB (except for the console cable, as this supplies power). Verify expected operation; reconnect
parts one at a time until the failure is recreated.
•Before replacing any major part, inspect the cables to/from it. Disconnect and inspect the
connectors on both ends, as well as the terminals on the boards. If capable, perform continuity
tests to verify all the conductors are intact. If no damage/corrosion noted, carefully reconnect,
ensuring proper seating and connection. Request replacement cables if at all suspicious.
USING THIS GUIDE
Read & understand the General Troubleshooting section above.
Given a problem description, link to the topic that appears most fitting from the ToC on the first page or
Find (ctrl-f) by keyword. Find the Green flowchart bubble that best describes the specific issue, and follow
the flow through asking questions, taking measurements, and suggesting corrective action. The
“Additional Information” section within each topic contains notes and details pertaining to that topic.
After each corrective action is taken, re-evaluate if the failure has been resolved. Some indications have a
straightforward order of attempts, and not all steps are always necessary if a lower-level fix resolves the
issue.

Additional Information
•Internet-connected consoles will check for (and perform, if found) updates at 1am by default. This
can be disabled or changed in Service Mode. USB updates are not recommended for any
common situations.
•If unable to navigate into software update menus, consider Touchscreen, Display, Freezing, or
Power failure.
•First Time Setup is initiated by press & holding the “MATRIX” logo, then touching the “First Time

Environment is set to Production, Equipment Type is selected correctly, Serial Numbers are
recorded correctly, and connection to the internet is established.

Additional Information
•Verify ERP mode settings as ERP mode will appear as “off”.
•By disconnecting everything but the console cable, failed components (i.e. bad RFID board, Wi-Fi
board, etc.) no longer cause faults. If the console appears to work as expected with nothing else
connected, failure is likely with one of the parts connected to it.

Additional Information
•“Freezing” and “Stalling” (and synonyms) are very general words that mean different things to
different people. In this Guide, they are taken to mean the console display is on, objects on the
screen may or may not be moving, but no touch or button response is recognized.
•No touch response can be interpreted as frozen; unlike many other consoles, ITC can only be
commanded by touch. See Touch Response topic for further calibration details.
•Touch Input/Display modules cannot be ordered separately from the UCB at this time.
•First Time Setup is initiated by press & holding the “MATRIX” logo, then touching the “First Time
Setup” button from the menu that appears. Ensure Facility ID is entered correctly, DAPI
Environment is set to Production, Equipment Type is selected correctly, Serial Numbers are
recorded correctly, and connection to the internet is established.

Additional Information
•For further instructions on loosening screws, see Bulletin NB-1907018
•To perform touch screen calibration:
oPress & hold “MATRIX” logo on the home screen for ~3 seconds
oTouch 3 0 0 1 ENTER
oIn MES mode, navigate to “Hardware” tab and press “Calibrate Touch Screen”
oPress & hold each target until “OK” appears. Follow directions on screen.
If touch response is too far off to navigate, Calibration can also be initiated by:
oCycle power & allow console to load to home screen
oPress & hold anywhere on the screen for ~35 seconds
oCalibration will begin after lifting touch. Follow directions on screen.
•Sweat, cleaner, water, and other contaminants on the touchscreen frequently cause apparent
failures. Properly cleaning the touchscreen is commonly all that’s required to resolve.
•Spraying cleaner directly on the screen is not recommended. Spray cleaner on a cloth and wipe
the screen with it.
•Touchscreens are not orderable separate from the UCB. Both must be replaced if either fails.

Additional Information
•The Console Cable between the Load Cell Pulley (LCB) and the DC Power Supply only delivers
power (pins 1&2 –7&8). If the data (pins 3 &6) fail on the CC to the UCB, errors can result.
Swapping the cables may restore function and can be a permanent fix. Alternatively, order new
Console Cable.

No
Didnt fix?
RFID tag failed.
Set up a new RFID
tag for that user
Additional Information
•For RFID issues (console acknowledges and reacts to RFID tag but not able to login), refer to this
RFID Service Bulletin.
•There are two RFID hardware reworks. The first rework is the addition of plastic standoff rings
and screws to stabilize the connection between the two boards. The pins of the connector
between the boards have been double-checked and soldered as well. The second rework is on
the USB connector. Pin 4&5 (GROUND&SHIELD) have been soldered together on the back side
of the board. RFID boards manufactured before May 2019 have not been reworked. Reference
NB-1907012.
•Bluetooth heart rate monitors are the only devices that can be connected to a console. No other
devices will connect to the console.

Check all items in
the Condition of

below
Small errors (+-10%)
in readout can
appear during high-
speed or heavy
lifting; this is normal
Additional Information
•Condition of the machine:
oWeight Guide Rods clean, lubricated, not damaged or bent?
oCables and pulleys move freely and easily, no physical interference or rubbing? Cables
routed & tensioned properly?
oAOW bracket adjusted properly? Well aligned with numbers, does it lift the # of AOWs
that it’s set to?
oAre the correct weight plates & AOW plates installed for the frame? Refer to Appendix A
for correct build.
•Glute machines manufactured before 2019 are known to have a wrong (10lbs weight stack with
2.5lbs AOWs) combination of weights. Properly manufactured machines should have 12 lbs. main
plates and three 2.5 lbs. AOW or 10 lbs. main plates and three 1.125 lbs. AOW.
•Most machines manufactured before March 2019 have questionable AOW precision. Most AOWs
are a little too heavy. This affects the calibration quality.
•When calibrating the load cell, make sure:
oNo AOWs are pinned
oThe reps are done gently and as far as possible but without hitting the travel limits
oNobody else is touching the machine
oThe machine is installed level and stable on the floor of the facility
