IN ELEC ® MOBILE 2 UL RASOUND USER MANUAL
CAUTION
• his unit should be operated at +°C to +°C and % to % Relative Humidity. he unit should be transported and
stored at -°C to +°C and % to % Relative Humidity.
• Use of parts or materials other than DJO’s can degrade minimum safety.
• Connect to this unit only items and equipment that have been specified in this IFU as part of the ME SYS EM or that have
been specified as being compatible with the ME SYS EM.
• DO NO disassemble, modify, or remodel the unit or accessories. his may cause unit damage, malfunction, electrical
shock, fire, or personal injury.
• DO NO permit foreign materials, liquids or cleaning agents to enter the unit, including, but not limited to, inflammables,
water, and metallic objects, to prevent unit damage, malfunction, electrical shock, fire, or personal injury.
• Before each use, inspect Ultrasound Applicator for cracks, which may allow the ingress of conductive fluid.
• Before each use, inspect Applicator cables, S IM cables and associated connectors.
• Handle Ultrasound Applicator with care. Inappropriate handling may adversely aect its characteristics.
• here are no user-serviceable parts inside the unit. If a malfunction occurs, discontinue use immediately and consult
dealer for repair service.
• In case of device unused with battery embedded, it is recommended to connect the device at least once every  months

 GENERAL WARNINGS AND PRECAU IONS E N
IN ELEC ® MOBILE 2 UL RASOUND USER MANUAL
WARNING
• his device should be used only under the continued supervision of a physician or licensed practitioner.
• Contaminated sponges, electrodes, leadwires, and gel can lead to infection.
• DO NO operate the Intelect® Mobile  within the vicinity or environment of an ultrasonic diathermy system.
• DO NO operate the Intelect® Mobile  within the vicinity or environment of any microware and RF shortwave
diathermy system.
• DO NO operate this unit in an environment where other devices are being used that intentionally radiate
electromagnetic energy in an unshielded manner.
• Portable RF communications equipment should be used no closer than  cm ( inches) to any part of the Intelect
Mobile , including cables specified by the manufacturer. Otherwise, degradation of the performance of this equipment
could result.
• Use of accessories, transducers and cables other than those specified or provided by the manufacturer of this equipment
could result in increased electromagnetic emissions or decreased electromagnetic immunity of this equipment and result
in improper operation.
• Battery replacement by inadequately trained personnel could result in fire or explosion. Please read carefully the battery
replacement instructions in the Mobile  IFU before attempting to replace the battery.
• Device is designed to comply with electromagnetic safety standards. his equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with instructions for use, may cause harmful
interference to other devices in the vicinity. Harmful interference to other devices can be determined by turning this
equipment on and o. ry 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 equipment to an outlet on a dierent circuit from that to which the other device(s) are connected
»Consult your authorized DJO dealer for help.
• Disconnect the system from the power source before attempting any maintenance, installation, removal, or replacement
procedures to prevent electrical shock and possible damage to system.
• he Intelect® Mobile  may be susceptible to Electro-Static Discharge (ESD) at greater than ± kV when first grasping
the Ultrasound applicator. In the event of such a discharge, the Intelect® Mobile  may display a permanent error. he
Intelect® Mobile  will terminate all active outputs (stim, ultrasound,), automatically place the unit in a safe state.
• o prevent Electro-Static Discharge (ESD) at greater than ± kV:
»Grasp and hold the Ultrasound prior to starting treatment. If the applicator must be put down prior to completion
of treatment, stop the current treatment first and then place the applicator in the holder.
»Maintain humidity in the use environment to at least % relative humidity.
»Floors should be wood, concrete, or ceramic tile. If floors are covered with synthetic material, DJO recommends
implementing additional controls to maintain relative humidity to at least %.
»Communicate these ESD-precautionary procedures to healthcare sta, contractors, visitors, and patients.
