CHAPTER 2: IMPORTANT SAFETY INSTRUCTIONS
2.1 BEFORE GETTING STARTED
The Matrix S3x-02 Stepper is intended for commercial use. To
ensure your safety and protect the equipment, read all instructions
before operating the stepper.
CHOOSING A SITE
The site should be well lit and well ventilated. Locate the Matrix
S3x-02 Stepper on a structurally solid and flat surface. The Stepper
should have a clearance of 24" on the back side from the wall or
other equipment. This zone is to allow easy access to the Stepper
and gives the user an easy exit path from the machine. If the site
has a heavy plush carpet, to protect the carpeting and machinery,
you should place a rigid plastic base under the unit.
Please do not place the Matrix S3x-02 Stepper in an area of high
humidity, such as the vicinity of a steam room, indoor pool, or sauna.
Exposure to intensive water vapor or chlorine could adversely affect
the electronics, as well as other parts of the machine.
2.2 READ AND SAVE THESE INSTRUCTIONS
To ensure your safety and protect the equipment, read all
instructions before operating the Matrix S3x-02 Stepper.
To ensure proper use of the Stepper, make sure that all users
read this manual. Remind the users that before undertaking any
fitness program, they should obtain complete physical examinations
from their physicians. If, at any time while exercising, the user
experiences dizziness, pain, or shortness of breath, nausea or feels
faint, he or she must stop immediately.
* This stepper is only to be used for its intended purpose described in
this manual. Do not use attachments that have not been recommended
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

CHAPTER 2: IMPORTANT SAFETY INSTRUCTIONS
2.3 ELECTRICAL REQUIREMENTS
The Matrix 3x Series Stepper is designed to be self powered, but a minimum of usage must be maintained to keep the battery charged
(approximately 6 hours a day). 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 Stepper will be plugged in, follow the requirements below.
MATRIX DEDICATED CIRCUIT/ELECTRICAL REQUIREMENT INFO
All Matrix Steppers 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 Steppers into should not have anything else running on that same circuit besides
other Steppers (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 Steppers 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 Stepper performance, the ground on this circuit must be non-looped. Please refer to NEC article 210-21 and 210-23. Your Stepper
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 Steppers can be powered on one dedicated circuit. (3 units per 15 Amp and 4 units per 20 Amp dedicated circuit.)
The S3x-02 Stepper saves its battery charge by moving into a shutdown mode whenever STEP FASTER appears on the display. If the user
does not maintain a step rate above 35 steps per minute, then a 30 second shutdown process begins. When the battery voltage is low, LOW
BATTERY appears on the display if the unit is moving into the shutdown mode. The following situation is the time to recharge the battery:
* If no one has used the unit for an extended period of time, the battery may need recharging.
* The unit continues to function with a low battery, however, user and program information is lost once the user stops.
If the battery must be recharged, use the optional power adapter
charging unit. The charger should be connected to the Stepper
for a minimum of eight hours to ensure a thorough charge. After
a completion of charge, the battery light turns from red into green
(see illustration). If LOW BATTERY still appears on the display with
a fully charged battery, the battery could be extinct. Please check
with an authorized service technician for replacing the battery.
CAUTION
The battery stored inside the unit contains materials hazardous to the
environment. Proper disposal of the battery is required by law.
GROUNDING INSTRUCTIONS:
The Matrix Stepper 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 Stepper 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.
