Foreword
This manual has been written for the owners and operators of the Intelect®Legend Combo, models 2C and 4C. It
contains general instructions on operation, precautionary practices, maintenance and parts information. In order to
maximize use, efficiency and the life of your unit, please read this manual thoroughly and become familiar with the
controls as well as the accessories before operating the unit.
Specifications put forth in this manual were in effect at the time of publication.
However, owing to Chattanooga Group's
policy of continual improvement, changes to these specifications may be made at any time without obligation on the part
of Chattanooga Group.
Product Description
With the same legendary performance, quality and value that has made the Intelect®name respected world-wide, the
Intelect®Legend Combo offers the convenience of a full-featured stimulator and ultrasound in one device. Easy to use
1-2-Go software makes this unit a pleasure to operate.
Features include Interferential, Premodulated, High Volt and Russian waveforms. Dual frequency ultrasound features a
5 cm
2
soundhead, which delivers 1 or 3.3 MHz frequencies, 10%, 20%, 50% and continuous duty cycle selections, and
head warming. Unique Electronic Signature™ control allows all available ultrasound applicators to be interchangeable.
Ultrasound operation is independent or in combination with Interferential, Premodulated and High Volt waveforms.
Models 2C and 4C of the Intelect Legend Combo are prescription devices used under the supervision or by the order of
a physician or other licensed healthcare provider.

Precautionary Instructions
1. CAUTION:
Read, understand and practice the precautionary and operating
instructions. Know the limitations and hazards
associated with using any electrical stimulation or ultrasound device. Observe the precautionary and operational
decals placed on the unit.
2. CAUTION: Do not operate the Intelect®Legend Combo when connected to any unit other than Chattanooga Group devices. Do
not operate the unit in an environment of short-wave diathermy use.
3. WARNING: Federal law restricts this device to sale by, or on the order of, a physician or licensed practitioner. This device should
be used only under the continued supervision of a physician or licensed practitioner.
4. CAUTION: This unit generates, uses and can radiate radio frequency energy, and if not installed and used in accordance with the
instructions, may cause harmful interference to other devices in the vicinity. However, there is no guarantee that
interference will not occur in a particular installation. Harmful interference to other devices can be determined by
turning this unit on and off or trying to correct the interference using one or more of the following: Reorient or
relocate the receiving device, increase the separation between the equipment, connect the unit to an outlet on a
different circuit from that to which the other device(s) are connected and/or consult the factory field service
technician for help.
5. CAUTION:
The Ultrasound generator should be routinely checked before
each use to determine that all controls
function normally; especially that the intensity control does properly adjust the intensity of the ultrasonic power
output in a stable manner.
Also, determine that the treatment time control does actually
terminate ultrasonic power
output when the timer reaches zero.
6. CAUTION: Use of controls or adjustments or performance of proce
dures other than those specified herein may result in
hazardous
exposure to ultrasonic energy.
7. CAUTION: This unit is not designed to prevent the ingress of water or liquids. Ingress of water or liquids could cause
malfunction of internal components of the system and therefore create a risk of injury to the patient.
8. CAUTION: DO NOT use sharp objects such as a pencil point or ballpoint pen to operate the buttons on the control panel as
damage may result.
9. WARNING: Equipment not suitable for use in the presence of flammable anesthetics mixture with air, oxygen, or nitrous oxide.
The warning symbol for this hazard is prominently displayed on the cabinet.

INTELECT LEGEND COMBO
10. WARNING: Keep electrodes separated during treatment. Electrodes in contact with each other could result in improper
stimulation or skin burns.
11. WARNING: For continued protection against fire hazard, replace fuses only with ones of the same type and rating.
12. WARNING:
Make certain that the unit is electrically grounded by connecting
only to a grounded electrical service receptacle
conforming to the applicable national and local electrical codes.
13. WARNING: This device should be kept out of the reach of children.
14. WARNING: Care must be taken when operating this equipment around other equipment. Potential electromagnetic or other
interference could occur to this or to the other equipment. Try to minimize this interference by not using other
equipment in conjunction with it.
15. CAUTION: This unit should be operated, transported and stored in temperatures between 59° F and 104° F (15° C and 40° C),
with Relative Humidity ranging from 30%- 60%.
16. CAUTION:
Handle ultrasound applicator with care. Inappropriate handling
of the ultrasound applicator may adversely affect its
characteristics.
17. CAUTION:
Inspect treatment head for cracks, which may allow the ingress
of conductive fluid before each use.
18. CAUTION: Inspect treatment head cables and associated connectors before each use.
19. WARNING: Use caution when operating in “Interferential” (IFC) mode. It is recommended to always use new electrode pads
when IFC modality is administered. Unseen residues on repeatedly used electrodes could possibly create an electrical
shock or burn sensation to the patient.
20. CAUTION: DO NOT raise intensity after treatment has been started.
21. DANGER: Patients with an implanted neurostimulation device must not be treated with or be in close proximity to any shortwave
diathermy, microwave diathermy, therapeutic ultrasound diathermy or laser diathermy anywhere on their body. Energy
from diathermy (shortwave, microwave, ultrasound and laser) can be transferred through the implanted
neurostimulation system, can cause tissue damage and can result in severe injury or death. Injury, damage or death
can occur during diathermy therapy even if the implanted neurostimulation system is turned "off."
Before administering any treatment to a patient you should become acquainted
with the operating procedures for each mode of
treatment available, as well as the indications, contraindications, warnings and precautions. Consult other resources for additional
information regarding the application of electrotherapy.

Indications
• Symptomatic relief of chronic, intractable pain.
• Management of pain associated with post-traumatic or postoperative conditions.
Contraindications
• This device should not be used for symptomatic pain relief unless etiology is established or unless a pain syndrome has
been diagnosed. This device should not be used on patients with demand type cardiac pacemakers. This device should

Warnings
• The long term effects of chronic electrical stimulation are unknown. Safety has not been established for the use of
therapeutic electrical stimulation during pregnancy.
• Adequate precautions should be taken when treating individuals with suspected or diagnosed heart problems, or epilepsy.
• Benefits of Interferential stimulation have not been established for pain of central origin.
• This device is to be used as a symptomatic treatment for pain and has no curative value. Patients should be cautioned
and their activities regulated if pain is suppressed that would otherwise serve as a protective mechanism.
• Electronic monitoring equipment (such as ECG monitors and ECG alarms) may not operate properly when electrical
stimulation is being utilized.
Precautions
• Isolated cases of skin rash may occur at the site of electrode placement following long term applications. The irritation
may be reduced by use of an alternate conductive medium or an alternative electrode placement.
• Effectiveness of this treatment is dependent upon patient selection.
Adverse Effects
• Skin irritation and burns beneath the electrodes have been reported with the use of therapeutic electrical stimulation.
Russian and High Volt
