TABLE OF CONTENTS

—3 — TABLE OF CONTENTS

Designed for versatility and durability, the Biodex Semi-Recumbent Cycle (SRC) and Semi-

Recumbent Cycle Clinical Pro meets the demands of orthopedic, cardiopulmonary, sports medi-

cine, wellness and general conditioning programs. Featuring a work range of 10 to 600 watts,

plus self-powered, self-charging capability, these cycles accommodate a wide variety of patient

profiles and can be used virtually anywhere. They are especially well-suited for treating weak or

deconditioned persons who cannot, or should not, use a standard cycle.

The Biodex SRC and SRC Clinical Pro cycles feature two modes of exercise operation: Isokinetic

Speed Control and Constant Power Effort Control. Because the internal battery is automatically

recharged when work rates reach or exceed 30 watts and 50 RPM, the cycles can be used in the

gym, at the clinic or on the sidelines – without cumbersome power cords. An AC adapter is pro-

vided for use at work rates below 30 watts and 50 RPMs. Large wheels make these cycles easy

to move.

Ergonomically designed and simple to operate, the Semi-Recumbent Cycles features a step-

through design that makes it easy for cyclists – including those with limited mobility – to get

into and out of the exercise position. The contoured seat with lumbar support and an indexed

track allows extensive front-to-back adjustment to ensurecomfort, safety and biomechanically

correct positioning. The seat can also be removed quickly for easy wheelchair access. A narrow

pedal spread and sturdy grab handle helps cyclists attain and maintain proper positioning for

efficient operation. The SRC accommodates users from 4'6" to 6'10" and weighing up to

350 pounds.

The easy-to-read, programmable LED display provides immediate user biofeedback for

increased motivation and compliance, maintaining all settings and LED displays for 60 seconds

after the workout is finished. Users can choose from quick-start operation that gets first-time

cyclists right into their exercise routine, or from five pre-programmed exercise profiles for each

mode of operation. All profiles can be modified with the panel controls to provide a multitude

of exercise programs to suit any individual’s need.

The SRC Clinical Proincorporates all of the above, plus a wider, rotating seat, cardiac monitor-

ing and adjustable pedal cranks.

NOTE: The SRC battery is shipped without the battery charged. Please plug in the AC Adapter and use

the SRC with the battery charger connected during the first 24 hours of use. It is not required to keep the

charger connected if work rates will exceed 30 watts on a regular basis, which is sufficient to charge the

battery. To use the SRC at work rates below 30 watts the AC Adapter is required.

—5 — PARTS AND ADJUSTMENTS

The Biodex SRC is easy to adjust for patient comfort. The seat can be moved forward or back

and the pedal straps can be tightened or loosened for a comfortable and secure fit. The follow-

ing section explains how to adjust your bike for optimum patient comfort and positioning.

Seat Front-to-Back Adjustment: The seat can be moved forward or back over a range of 20" to

match user comfort requirements. Proper seat front-to-back positioning will allow the user to

pedal comfortably while maintaining the lordotic curve.

To adjust the seat front-to-back position:

• Pull out on the Seat Front-to-Back Release Handle. While holding the handle out, slide the seat

either forward or back to the desired position. To lock the seat in position, release the handle

and make sure it engages in the appropriate hole. To ensure reproducible positioning, note the

seat position as per the Seat Front-to-Back Position Scale, located on the seat slide track.

Pedal Foot Strap Adjustment: The Pedal Foot Strap can be adjusted to fit any foot or shoe.

To adjust the foot strap:

• Free the foot strap for adjustment by pulling the strap down and over the rubber catch.

To secure the strap, pull the desired hole over the rubber catch from the bottom up.

Seat Removal: The seat can be removed for wheelchair use.

• Loosen the rear seat stop.

• Pull out on the seat front-to-back release handle and slide the seat offthe back of the trolly.

You can now easily position a wheelchair patient for exercise.

NOTE: Do not sit on seat when removed.

Rotating Seat (Clinical Pro only): To aid the user in getting on and off the Semi-Recumbent

Cycle Clinical Pro, an optional rotational seat can be turned left or right.

To rotate the seat:

• Pull forward on the Seat Rotation Handle to release the seat. You may now swivel the seat left

or right until it engages in either position.

• With the seat locked in the desired position, instruct the patient to sit down. Pull out on the

Seat Rotation Handle and rotate the seat until it engages in the forward locked position.

Adjustable Pedal Cranks (Clinical Pro only): The optional Adjustable Pedal Cranks can be set

to accommodate or define a knee arcto avoid a painful point in the user’s range of motion, or to

protect reconstructed ligaments.

To adjust the pedal crank position:

• Loosen the Pedal Adjust Lever by turning it in a counterclockwise direction.

•Pull out on the Pedal Adjust Pull Pin and, while holding it out, slide the pedal to the

desired position.

• Release the Pedal Adjust Pull Pin and ensure that it locks into the appropriate pedal

shaft detente.

•Tighten the Pedal Adjust Lever by turning it in a clockwise direction. (Be sure to position the

lever so it will not interfere with user exercise. To do this, simply pull out on the lever handle

and turn it to the desired position.)

2. ASSEMBLY INSTRUCTIONS

PARTS AND ADJUSTMENTS — 6 —

Adjustable Pedal Cranks (Clinical Pro only):

Adjustable pedal cranks can be used to allow patients with limited knee flexion to begin their

cycling program earlier. Standard pedal crank lengths typically require 110 to 115 degrees of

knee flexion to complete full pedal revolutions. Adjustable pedal cranks let patients perform

complete revolutions with as little as 80 to 90 degrees of flexion. These pedal cranks also provide

ameans for establishing knee flexion limits to avoid painful points in the patient’s range of

motion, or to protect reconstructed ligaments.

—7 — PARTS AND ADJUSTMENTS

Although the SRC offers advanced programming capability, it also features a "Quick-Start" func-

tion that allows the user to immediately begin cycling with factory preset default values serving

for the programmable system parameters.

Quick-Start operation is simple. Seat the user, adjust the seat forward and back position and foot

pedal straps as necessary, and proceed as described below:

1. Press <Power On> to power-up. After a brief self-test (which includes display of the current

software version,) the system beeps to signify that it is ready to begin collecting data.

2. Grasp the SRC fixed handlebars (or optional heart rate handgrips) and begin pedaling.

3. Use the <+> and <-> buttons to adjust effort level (#5 at bottom of the display).

To stop the system at any time, simply stop pedaling. All parameters will continue to display for

one minute before the system shuts off. If you want to turn the system off and automatically

reset the display, press <Power ON > again.

NOTE: Standard SRC’sdefault to Constant Power Effort Control exercise mode. SRC Clinical Pro’sout-

fitted with retro-cycling default to Isokinetic exercise mode. A green LED on the display activates to show

the selected mode. To change modes, press <Select Exercise>(4) at the bottom of the display.

NOTE: To provide heart rate monitoring (SRC Clinical Pro only), the subject must hold onto both heart

rate contact handgrips.

NOTE: For the first 24 hours of operation, the SRC should be used with the AC Adapter.

the value to the desired setting (for more accurate metabolic calculation).

2. Set the Exercise Duration Time: Press <Set Time> and then use the <+> or <-> arrow keys to

adjust the value to the desired setting.

NOTE: Time counts down if you set the exercise duration. Time counts up if you do not set this value.

3. Select the Desired Profile: By pressing <Select Profile>, you can scroll through the available

profiles. When you see the profile desired, proceed to step 4.

4. Select the Exercise Mode: Press <Select Exercise> to toggle between Isokinetic (strength exer-

cise/speed control) and Aerobic Exercise (constant power/effort control).

5. Adjust Isokinetic Speed or Constant Power Effort Level: Use the <+> or <-> arrows to adjust

the Isokinetic speed or constant power effort level to the desired level.

NOTE: Tomake changes to programmed parameters, press <Clear Settings>. This will set all

parameters back to default values. You can then begin again at step one, above.

6. Grasp the SRC fixed handlebars or heart rate contact handgrips, and begin pedaling.
