feature may not function fully. The charging does not need to be
continuous for 3-4 hours, but over combined workouts equaling 3-4
hours.

Preventative maintenance and daily cleaning will prolong the life and look
of your MATRIX U3x-01 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.

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.
1) Start pedaling and press the FITNESS TEST key.

standard digital contact heart rate sensors and are POLAR telemetry
compatible. The heart rate control workout mode allows the user to
program their desired heart rate zone, and the bike will automatically
adjust the level based upon the user's heart rate. The heart rate
zone is calculated using the following equation: (220-Age)8%=target
heart rate zone. The user must wear a POLAR telemetric strap or
continually hold onto the contact heart rate grips for this workout.
Locate the metal sensors on the handlebars of the bike. Notice
that there are two separate pieces of metal on each grip. You must
be making contact with both pieces of each grip to get an accurate
