CHAPTER 2: IMPORTANT SAFETY INSTRUCTIONS
2.2 ELECTRICAL REQUIREMENTS
The Matrix 3x Series Upright Bike is designed to be self powered. NOTE: If an add on TV (using a bracket) is added to the unit, it must be
plugged in, or the TV will not operate correctly. If the Bike will be plugged in, follow the requirements below.
MATRIX DEDICATED CIRCUIT/ELECTRICAL REQUIREMENT INFO
All Matrix Bikes require the use of a 15 amp or 20 amp “dedicated circuit,” with a non-looped (isolated) neutral/ground, for the power requirement.
Quite simply this means that each outlet you plug Bikes into should not have anything else running on that same circuit besides other Bikes (up to
3 per 15 amp circuit and 4 per 20 amp circuit). The easiest way to verify this is to locate the main circuit breaker box, and turn off the breaker(s)
one at a time. Once a breaker has been turned off, the only thing that should not have power to it are the Bikes in question. No lamps, vending
machines, fans, sound systems, or any other item should lose power when you perform this test.
Non-looped (isolated) neutral/grounding means that each circuit must have an individual neutral/ground connection coming from it, and terminating
at an approved earth ground. You cannot “jumper” a single neutral/ground from one circuit to the next.
In addition to the dedicated circuit requirement, the proper gauge wire must be used from the circuit breaker box, to each outlet that will have the
maximum number of units running off of it. If the distance from the circuit breaker box, to each outlet, is 100 ft or less, then 12 gauge wire may be
used. For any distance greater than 100 ft from the circuit breaker box to the outlet, 10 gauge wire must be used.
For your safety and Bike performance, the ground on this circuit must be non-looped. Please refer to NEC article 210-21 and 210-23. Your Bike is
provided with a power cord with a plug listed below and requires the listed outlet. Any alterations of this power cord could void all warranties for
this product. Multiple Bikes can be powered on one dedicated circuit. (3 units per 15 Amp and 4 units per 20 Amp dedicated circuit.)
GROUNDING INSTRUCTIONS:
The Matrix U3x-02 Upright Bike must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for
electric current to reduce the risk of electric shock. The Bike is equipped with a cord having an equipment grounding conductor and a grounding
plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and
ordinances. If the user does not follow these grounding instructions, the user could void the Matrix limited warranty.
DANGER: Improper connection of the equipment grounding conductor can result in the risk of electric shock. Check with a qualified electrician
if the user is in doubt as to whether the product is properly grounded. Do not modify the plug provided with the product if it will not fit the outlet,
have a proper outlet installed by an electrician.

CHAPTER 3: PREVENTATIVE MAINTENANCE
3.1 RECOMMENDED CLEANING TIPS
Preventative maintenance and daily cleaning will prolong the life and look
of your MATRIX U3x-02 Bike
Please read and follow these tips.
* Position the equipment away from direct sunlight. The intense UV
light can cause discoloration on plastics.
* Locate your equipment in an area with cool temperatures and low
humidity.
* Clean with a soft 100% cotton cloth.
* Clean with soap and water or other non-ammonia based all purpose
cleaners.

for any reason. They contain important information. If unreadable
or missing, contact Matrix Fitness Systems for a replacement at
866-693-4863 or www.matrixfitness.com.
MAINTAIN ALL EQUIPMENT. Preventative maintenance is the
key to smoothly operating equipment. Equipment needs to be
inspected at regular intervals. Defective components must be
kept out of use until they are repaired. Ensure that any person(s)
making adjustments or performing maintenance or repair of any
kind is qualified to do so. Matrix Fitness Systems will provide
service and maintenance training at our corporate facility upon
request or in the field if proper arrangements are made.

CHAPTER 8: TROUBLESHOOTING
8.10 TROUBLESHOOTING - HEART RATE ISSUES
HEART RATE FUNCTION DOES NOT WORK OR IS READING INCORRECTLY
POSSIBLE CAUSES:
1) The HR grips are not hooked up correctly.
2) The HR grip wiring is damaged.
3) The console or HR board is not properly grounded.
4) The console, HR board, or wiring between are bad.
SOLUTION:
1) Perform a DC Voltage test on the HR grips.
a. With one prong of a multi meter on each of the plates on one side of the HR grip set (Figure A), a voltage reading of between .5 and 2.0
should be seen. If the reading is correct, the issue is not with the HR grips or grip wiring.
b. If the reading is not correct, remove the screws holding the halves of the HR grip together and check the connection of the wiring to the
grips (Figure B).
2) Remove the console from the unit and verify continuity of the HR grip wiring. With a multi meter set for ohms, place one prong on the HR grip
wiring coming up the console mast (Figure C), and the other on the appropriate plate (match red with red and white with white).
a. An ohm reading of less than 1 should be received. If it is higher, replace the HR grip wiring.
3) Perform a continuity check on the console (See Service Bulletin - Continuity Test on Matrix Bikes).
a. Once the console continuity is confirmed, perform a continuity check on the HR board ground wire. With a multi meter set for ohms, place
one prong on the HR board ground wire (Figure D), and the other on the console ground wire. An ohm reading of less than 1 should be received.
If it is higher, replace the HR board.
4) If all the troubleshooting listed above has been performed, and the unit still has HR issues, replace the HR board.
a. If the HR board does not resolve the issue, replace the console.

1. Sections 8.11 - 8.14 will help with diagnosing problems with TV and entertainment related equipment that is produced by Matrix Fitness Systems.
2. The U3x-02 Bike has the capability of adding an external 15" TV with a bracket. A Matrix brand external TV will look similar to the TV in Figure A.
Your control keypad should look similar to Figure B. If your equipment looks different contact Matrix or the manufacturer of your TV equipment if
known.
FIGURE A FIGURE B
3. Verify how your TV is mounted, compare your machine to Figure C which shows an external 15" TV directly mounted to a unit with a 3x console.
FIGURE C
4. For Matrix produced and mounted equipment you can use the information outlined in this section to help with any connection and power
issues you may have. If you have questions that are specic to the TV alone (settings, programming, menu options, etc) please see the
entertainment owner’s manual.
21
CHAPTER 8: TROUBLESHOOTING
8.12 ENTERTAINMENT TROUBLESHOOTING – PICTURE FUZZY OR UNCLEAR
1. Remove the TV back cover (Figure A) Using a veried good piece of coax cable, hook the coax directly to the TV jack. This bypasses internal
connections for your machine or TV stand (Figure B).
FIGURE A FIGURE B
2. If this does not clear your picture the issue is with the club's signal. Make sure that the coax has a signal strength of at least 10db.
3. If Step 1 does clear your picture, check the internal cables and ttings inside your machine. Make sure you have no damage (kinks, cuts etc)
and no stray wires or poor ttings on the ends of the cables anywhere that the coax cable is connected (Figures C & D). Fittings should have a
clean ush connector and no stray aluminum strands touching the center conductor. Replace or repair any suspect cables.
FIGURE C FIGURE D
4. If nothing is visibly wrong with any of the cables, ttings, or connectors replace the internal coax cables and connectors with known good
parts.
22
CHAPTER 8: TROUBLESHOOTING
8.13 ENTERTAINMENT TROUBLESHOOTING -TV WILL NOT TURN ON
1. If you have no picture at all check to see if you have any status lights on your entertainment keypad or TV. Status lights should be red when
off or in standby mode, and green when the TV is powered on. If you have lights of any color skip to Section 8.14.
2. Remove the TV back cover (Figure A) and check the connection of the TV power wire at the TV (Figure B). Also check the TV power wire
connection at the console (Figure C).
FIGURE A
FIGURE B
FIGURE C
3. After you have veried all connections are secure and a problem still exists verify power at the outlet (Figure D). If the outlet is not outputting
120 Volts, check tness room power.
4. If internal TV power wire connections are good, verify 12 Volts power at the TV power wire where it plugs into the TV (wire in Figure B, shown
with multi - meter in Figure E). If 12 Volts are present, the issue is likely with the TV itself, contact Matrix Customer Service.
FIGURE D
FIGURE E
23
CHAPTER 8: TROUBLESHOOTING

CHAPTER 10: BIKE SPECIFICATIONS AND ASSEMBLY GUIDE
10.4 ADJUSTING THE PEDAL STRAPS AND SEAT
ADJUSTING THE PEDAL STRAPS
The straps are designed to fit your individual foot size and should be adjusted tight enough to keep your foot from slipping. The pedals include
spring loaded clips for easy adjustment. To tighten the strap, pull down the open end of the strap. To loosen the strap, push down on the top of
the clip and pull the strap up. Release the clip to lock the strap in place.
ADJUSTING THE U3x-02 SEAT
To determine whether or not the seat requires adjustment, sit on it
and place your feet on the pedals. The user's knees should bend
slightly when the pedal is at the lowest point of its rotation. It should
be possible to pedal without locking the knees or shifting in the seat.
The Matrix U3x-02 Bike features a vertical ratchet seat adjustment
system, which makes it easy and safe to change the height of the
seat quickly.
To raise the seat, pull the seat upward to the desired height, and let
it lock into place. Test and re-adjust the seat height as necessary.
To lower the seat, first get off the bike. Holding the seat, pull out the
yellow seat post knob. Let the seat slide down to the desired height
and release the yellow seat post knob. Test and re-adjust the seat
height as necessary.
