nausea or feels faint, he or she must stop immediately.
* This bike is only to be used for its intended purpose described
in this manual. Do not use attachments that have not been recom-
mended by Matrix.
* Never drop or insert objects into any opening. Keep hands away
from moving parts. If the item cannot be reached, contact a Matrix

* Never operate the unit if it is damaged, not working properly, when
it has been dropped, or has been dropped in water.
* Keep hands and feet clear at all times from moving parts to avoid
injury.
* Do not use this product outdoors, near swimming pools or in areas
of high humidity.
* Do not operate where aerosol (spray) products are being used or

CHAPTER 2: IMPORTANT SAFETY INSTRUCTIONS

2.2 ELECTRICAL REQUIREMENTS
GROUNDING INSTRUCTIONS:
The Matrix U5x-03 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.
The Matrix 5x Series Upright Bike is designed to be self powered. NOTE: If an add on TV (using a bracket) or Virtual Active is added to the
unit, it must be plugged in, or the TV and Virtual Active 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.)
CHAPTER 2: IMPORTANT SAFETY INSTRUCTIONS

Preventative maintenance and daily cleaning will prolong the life and look
of your MATRIX U5x-03 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.
* Wipe seats, pedals, console, heart rate grips, and the handlebar clean
after each use.
* Do not pour liquids directly onto your equipment. This can cause dam-
age to the equipment and in some cases electrocution.
* Check pedal straps weekly for wear.
* Adjust leveling feet when equipment wobbles or rocks.
* Maintain a clean area around the equipment, free from dust and dirt.
DO NOT use any equipment that is damaged or has worn or
broken parts. Use only replacement parts supplied by Matrix
Fitness Systems.
MAINTAIN LABELS AND NAMEPLATES. Do not remove labels
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.

3.3 CARE AND MAINTENANCE INSTRUCTIONS
In order to maximize life span, and minimize down time, all MATRIX equipment requires regular cleaning, and maintenance items performed on
a scheduled basis. This section contains detailed instructions on how to perform these items and the frequency of which they should be done.
Some basic tools and supplies will be necessary to perform these tasks which include (but may not be limited to):
* Metric Allen wrenches
* #2 Phillips head screwdriver
* Adjustable wrench
* Torque wrench (capability to read foot lbs and inch lbs)
* Lint free cleaning cloths
* Teflon based spray lubricant such as "Super Lube" or other Matrix approved products.
* Mild water soluble detergent such as "Simple Green" or other Matrix approved products
* Vacuum cleaner with an extendable hose and crevasse tool attachment.
You may periodically see addendums to this document, as the Matrix Technical Support Team identifies items that require specific attention, the
latest version will always be available on the Matrix web site at www.matrixfitness.com.
DAILY MAINTENANCE ITEMS
1) Look and listen for loose fasteners, unusual noises, and any other indications that the equipment may be in need of service.
2) Clean the bike before and after each use, including:
a. Use a damp, soft cloth with water or mild liquid detergent to clean all exposed surfaces. DO NOT use ammonia, chlorine, or any acid
based cleaners. NOTE: Spray cleaner onto a cloth before using, never spray cleaner directly onto the equipment.
b. Keep the console display free of fingerprints and salt build up caused by sweat.
WEEKLY MAINTENANCE ITEMS
1) Frequently vacuum the floor beneath the unit to prevent the accumulation of dust and dirt which can affect the smooth operation of the unit.
2) Check the pedal straps for damage.
3) Clean the grooves on the foot pedals.
MONTHLY MAINTENANCE ITEMS
1) Inspect the console, seat, pedals, and shrouds for damage.
2) Tighten the pedals onto their respective cranks using a 15 mm wrench.
3) Adjust the leveling feet if equipment rocks or wobbles.
4) Clean the seat post track with a 100% cotton cloth.
YEARLY MAINTENANCE ITEMS
1) Remove the front shrouds and check the belt for damage, alignment, and proper tension.

4.5 WORKOUT SETUP STEPS - FITNESS TEST
FITNESS TEST -The Cooper Fitness Test measures cardiovascular fitness and proves an estimated sub-maximal VO2 result. It is based
on power output according to ACSM standards and was developed by the Cooper Institute© (www.cooperinstitute.org). User RPMs must
remain between 60-80 RPM during the test. The test will end when the user can no longer maintain this speed. Use of a heart rate strap is
optional but provides more data.
The test starts at a low intensity level and gradually increases in intensity (difficulty) every 2 minutes. As it increases, the user must maintain
60-80 RPM to advance to the next level. The test could take upwards of 30+ minutes for very fit individuals. Once the test ends a recovery
period (cool down) will begin and the user's results are calculated and displayed. Results are based on the number of stages completed.
