Data Readouts
As you exercise, the Arc Trainer 425A keeps track of the following data:
strides
minute
Distance - The total accumulated distance, in miles or kilometers, during your
workout. NOTE: Depending on the defaults you’ve chosen this measurement will
show in English or Metric.
Calories - The total accumulated calories burned during your workout. Your
weight must be correctly set before beginning your workout for this
measurement to be most accurate.
Calories Per Hour - Calculation of present workloads energy exertion in
Calories per Hour. Your weight must be correctly set before beginning your
workout for this measurement to be most accurate.
Metabolic Equivalent - Relates to the user’s energy expenditure. A MET is a
basic unit of measurement that is used to compare relative work between
individuals and activities. One MET is the amount of oxygen an individual
consumes at rest. For example two mets would be twice that amount. If an individual were working at four METs he/she would be consuming oxygen at a rate
equal to four times their resting consumption. METs can be used to
compare walking on a grade with running or even to cycling and other activities.
See The Workout Profile in this chapter for more information.
Watts - Present workload energy exertion in Watts.
Strides Per Minute - Your average number of strides per minute at your current
speed.
Heart Rate - Your current heart rate. Heart rate will appear when a signal is
introduced. Use either the handgrips for Contact Heart Rate or a Polar compatible
heart rate transmitter. See Heart Rate LED for a description of colors.
Operation
Page 3-6
Cybex Arc Trainer 425A Owner’s Manual
To review accumulated data after a program: The display automatically cycles through your
accumulated workout data during the Workout Review for 20 seconds (default setting). NOTE: Heart
rate is not displayed during a Workout Review.
Displaying Heart Rate
In order to display your heart rate, you must either use a Polar compatible heart rate transmitter belt (not
included) or hold the handgrips to use Contact Heart Rate.
Contact Heart Rate - Hold the handgrips on the handles until a heart rate is displayed, typically less
than thirty seconds. For best results, hold the handgrips lightly and ensure that your hands contact both
the front and back sensors of each grip. NOTE: Hold your hands as steady as possible as
movement can cause interference on the contacts.
Factors that can interfere with the heart rate signal include:
• excessive movement
• body composition
• hydration
• too loose grip
• too tight grip
• excessive dirt, powder or oil
• resting or leaning on the grips
Contaminants, such as hand lotions, oils or body powder, may come off on the contact heart rate grips.
These can reduce sensitivity and interfere with the heart rate signal. Therefore, ensure you have clean
hands when using the contact heart rate.
Polar Compatible Reception - To use this feature, a Polar compatible heart rate transmitter belt must
be worn. To view heart rate continuously, press the Scan key when the Heart LED is lit or press the
Heart key.
Heart Rate LED
When the handgrips are held the center display switches to show the heart rate in beats per minute
(BPM) if you are not scanning. For several seconds the display will show “---”. Once the actual heart
rate is determined the center window displays the BPM and the Heart LED lights up. See Figure 2. The
color of the light represents a scale of low to high target heart rate.

Manual Mode use the Resistance + - keys. To increase or decrease the incline while in Manual Mode
use the Λ V arrows.
When you workout in Manual Mode, be sure to include a three-to-five minute warm-up and cool-down
period. You can warm-up by setting a low resistance at zero incline and then gradually increase the
incline and resistance to the target for your workout. Reverse this process for your cool-down period,
lowering the resistance gradually and returning the incline to zero.
The Workout Profile
The Workout Profile matrix in the center of the display uses columns of lights to show the progress of
your workout. The height of the column represents METS, specifically the highest METS you reached in
that period. Each column represents 1 minute of your total workout time when in Manual Mode and 15
seconds in every other program.
NOTE: It is conceivable to have two segments of different speed and elevation combinations in the
same met range.
Range of Motion
Press the Incline Λ V keys to change the elevation in increments of 10%. The elevation rises or lowers
in the shape of an arc ranging from 12 to 34.5 degrees (with the chord of an arc). Depending upon the
incline you choose the primary and secondary muscles trained will vary. See Figure 3.

Speed Interval 1
Program Overview
This program is designed to introduce the user to some higher intensity training. The program uses a fixed
incline with resistance using a repeating 1:2 work to rest ratio. Each work segment lasts 30 seconds and
each rest segment lasts 60 seconds. The resistance of the rest segments is 60 to 65% that of the work
segments. Interval training is designed to tax both the aerobic and anaerobic energy systems. During
the high intensity segments the anaerobic energy system is taxed. During the low intensity segments
the aerobic energy system is used while the “oxygen debt” incurred during the high intensity segments
is repaid. The repetition of the high intensity segments forces the body to adapt to the greater demands
thereby helping the user to develop higher performance capabilities. See table below and Figure 4.

Speed Interval 2
Program Overview
This program is designed for those who desire a higher intensity training interval training program. The program uses a
fixed incline with resistance using a repeating 1:1 work to rest ratio. Each work segment lasts 60 seconds and each rest
segment lasts 60 seconds. The resistance of the rest segments is approximately 55 to 65% that of the work segments.
Interval training is deigned to tax both the aerobic and anaerobic energy systems. During the high intensity segments
the anaerobic energy system is taxed. During the low intensity segments the aerobic energy system is used while the
“oxygen debt” incurred during the high intensity segments is repaid. In Interval 2 the extended work segment creates a
greater “oxygen debt” than Interval 1 putting greater demand on both energy system and the repayment of the “oxygen
debt” forcing even greater adaptation to the imposed demands. See table below and Figure 5.

Hills Interval
Program Overview
The Hills program is designed to give the user the experience of hiking in a hilly terrain. This program
uses intervals of moderate resistance and incline to simulate relatively at areas and intervals of
substantially greater incline and resistance to simulate steeper grades. Likewise the two-minute work
segments are intended to tax the users capabilities, while the two-minute rest allows for recuperation and
allows for repeated work segments. See table on next page and Figure 6.

Program Overview
The Valleys program provides a contrasting mix of incline and resistance. The program uses a ve
minute core during which the resistance is increased and the incline is reduced in the rst three
minutes followed by and a reduction in resistance and an increase in incline until the valley repeats
itself. This program is designed specically to contrast the Ramps and Hills programs for added
training variety. See table below and Figure 7.

Ramps
Program Overview
The Ramps program is similar to the Hills program but uses a more linear ramp to both incline and resistance from
segment to segment. Ramps is comprised of a 3 ½ minute core where the incline and resistance both increase
over the rst 2 ½ minutes followed by a one minute reduction of both incline and resistance. The
reduction in incline and resistance is designed to provide a working rest period before the ramp is repeated. See
table below and Figure 8.

Hills
Program Overview
The Hills program uses a 3 ½ minute core where the incline and resistance both increase over the first
2 ½ minutes followed by a one minute reduction of both incline and resistance. The reduction in incline
and resistance is designed to simulate reaching the top a hill and level ground. The climb up the hill is
then repeated. See table below and Figure 9.

Cardio
Program Overview
The Cardio program is designed for experienced users that desire a high intensity cardiovascular
training experience. The two-minute work interval with high resistance ensures that the aerobic energy
system is completely taxes, while the subsequent two-minute rest interval allows for recovery enabling a
repeat at the higher work rate. Additionally, a higher incline level is used during the recovery interval to
discourage blood pooling, ensuring more complete recovery. See table below and Figure 11.

Cleaning Your Arc Trainer 425A
WARNING: To prevent electrical shock, be sure the unit is unplugged from the electrical outlet
before performing any cleaning or maintenance procedures.
When cleaning your unit spray a mild cleaning agent, such as a water and dish soap solution, on a
clean cloth first and then wipe the unit with the damp cloth.
NOTE: Do not spray cleaning solution directly on the unit. Direct spraying could cause damage to the
electronics and may void the warranty.
After Each Use - Wipe up any liquid spills immediately. After each workout, use a cloth to wipe up any
remaining perspiration from the handles and painted surfaces.
Be careful not to spill or get excessive moisture on the console and display overlays, as this might
create an electrical hazard or cause failure of the electronics.
As Needed - Vacuum any dust or dirt that might accumulate under or around the unit. Cleaning this
area should be done as often as indicated in the Service Schedule.
WARNING: Keep wet items away from inside parts of the unit. Electrical shock could occur
even if the unit is unplugged. Do not touch components on the lower board. A
charge can remain after unplugging the power cord.
To clean inside the unit, remove the four Phillips head screws securing the access cover in place. Use
a vacuum attachment or hand vacuum to clean the exposed elevation assembly and remove dirt and
debris off of internal components.
Use a dry cloth to wipe all exposed areas. Replace the access cover and secure it with the screws when
finished.
Lift the rear of the unit and roll it back from its present position so as to vacuum the floor area
underneath the unit. When finished, return the unit to its normal position.
Contact Heart Rate Grips - Contaminants, such as hand lotions, oils or body powder, may come off
on the contact heart rate grips. These can reduce sensitivity and interfere with the heart rate signal. It is
recommended that the user have clean hands when using the contact heart rate. Clean the grips using
a cloth dampened with a cleaning solution containing alcohol. The grips are the only part of the unit you
should use a cleaning solution containing alcohol.

Drive Belt Maintenance
There are two drive belts that may become loose, worn or
cracked. See Figure 1.
Primary Belt - This is the wider of the two belts. It has
grooves that keep it aligned on the large upper pulley. It is
unlikely that the primary belt will become loose because it is a
stretch-fit belt.
Secondary Belt - This is the narrower of the two belts. It has
grooves that keep it aligned on the flywheel’s drive
pulley. It is unlikely that the secondary belt will become loose
because it is a stretch-fit belt.

Return Material Authorization (RMA)
The Return Material Authorization (RMA) system outlines the procedures to follow when returning
material for replacement, repair, or credit. The system assures that returned materials are properly
handled and analyzed. Follow the following procedures carefully.
Contact your authorized Cybex dealer on all warranty-related matters. Your local Cybex dealer will
request an RMA from Cybex, if applicable. Under no circumstances will defective parts or equipment be
accepted by Cybex without proper RMA and an Automated Return Service (ARS) label.
1. Call the Customer Service hotline listed on Page 6-1 for the return of any item that is defective.
2. Provide the technician with a detailed description of the problem you are having or the defect in the
item you wish to return.
3. Provide the model and serial number. The serial number is located on the front of the unit as shown
in Figure 1. The serial number begins with a letter, for example: R09-101331100.
4. At Cybex’s discretion, the technician may request that you return the problem part(s) to Cybex for
evaluation and repair or replacement. The technician will assign you an RMA number and will send
you an ARS label. The ARS label and RMA number must be clearly displayed on the outside of the
package that contains the item(s) to be returned. Include a description of the problem, the serial
number of the unit and the name and address of the owner in the package along with the part(s).

NOTE: All inspections
and repairs must be
performed by trained
service personnel only.
Damaged Parts
Materials damaged in shipment should not be returned for credit. Shipping damages are the
responsibility of the carrier (UPS, Federal Express, trucking companies, etc.).
Apparent Damage - Upon receipt of your shipment, check all boxes carefully. Any damage seen with
a visual check must be noted on the freight bill and signed by the carrier’s agent. Failure to do so will
result in the carrier’s refusal to honor your damage claim. The carrier will provide you with the required
forms for filing such claims.
Concealed Damage - Damage not seen with a visual check upon receipt of a shipment but noticed later
must be reported to the carrier as soon as possible. Upon discovery of the damage, a written or phone
request to the carrier asking them to perform an inspection of the materials must be made
within ten days of the date of delivery. Keep all shipping containers and packing materials: they will be
needed as part of the inspection process. The carrier will provide you with an inspection report and the
necessary forms for filing a concealed damage claim. Concealed damage is the carrier’s responsibility.
Ordering Parts
Fax orders to 508-533-5183. To speak with a customer service representative, call 888-462-9239 (for
customers living within the USA) or 508-533-4300 (for customers outside the USA).
