Convention
Description
<space>
Indicates that you must press the spacebar. When instructions are given for typing a precise text string with one or more spaces, the point where you must press the spacebar is indicated as <space>. This ensures that the correct number of spaces is inserted in the correct positions within the literal text string. The purpose of the < > brackets is to distinguish the command from the literal text within the string.
Enter
Indicates that you must press the Enter or Return key on the keyboard. Do not type Enter.
>
The greater than symbol, or right angle bracket, is a concise method to indicate a sequence of menu selections. For example, the statement “From the main menu, select System > Setup > Options to open the Option Activation window” replaces the following: 1.
From the main menu, select System to open the System menu.
2.
From the System menu, select Setup to open the Setup menu.
3.
From the Setup menu, select Options to open the Option Activation window.

Introduction
WARNING: EXPLOSION HAZARD - Flammable anesthetic vapors or liquids can cause explosions. Do NOT use in the presence of flammable anesthetic vapors or liquids. WARNING: PERSONAL INJURY HAZARD - To avoid injury, follow physicians’ or qualified health care providers’ instructions carefully during use of the equipment. WARNING: ENTANGLEMENT HAZARD- To avoid injury, keep hands, hair, jewelry, loose clothing and patient cables away from moving parts. WARNING: STUMBLE HAZARD - To avoid injury to patient, operate the treadmill with 185 cm (72 in) of clearance at the rear (end opposite the motor). WARNING: SHOCK HAZARD - Improper use of this device presents a shock hazard. Strictly observe the following warnings. Failure to do so may endanger the lives of the patient, the user, and bystanders. To reduce the risk of electric shock do NOT remove cover (or back). Refer servicing to qualified personnel. When disconnecting the device from the power line, remove the plug from the wall outlet first, before disconnecting the cable from the device. Otherwise there is a risk of coming in contact with line voltage by inadvertently introducing metal parts in the sockets of the power cord. Devices may be connected to other devices or to parts of systems only after making certain that there is no danger to the patient, the operators, or the environment as a result. Standards IEC 60601-1-1/EN60601-1-1 must be complied with in all cases. WARNING: LIFTING HAZARD - The treadmill is too heavy to lift, lower or move safely by one person. Serious bodily injury or damage to the treadmill may result. A minimum of two people are required when lifting, lowering or moving the treadmill. WARNING: STUMBLE HAZARD - Rapid changes in treadmill speed and/or grade during a stress test may result in injury. DO NOT rapidly change treadmill speed and/or grade during a stress test. WARNING: TREADMILL CHANGES - DO NOT place feet under the treadmill during operation or while decreasing the treadmill grade to avoid injury.

Introduction
WARNING: STUMBLE HAZARD - While the emergency stop switch is depressed or not present or when power is not applied to the treadmill the walking belt is not locked. The walking belt in this condition is allowed to move which could cause a person to lose balance and fall if they are standing on the belt. The risk of belt movement is increased with higher treadmill grades or inclines. CAUTION: STUMBLE HAZARD - The emergency stop switch is a safety device for use only in emergency situations to stop the treadmill. The walking belt will stop quickly. Once stopped and while the switch is depressed, the treadmill walking belt will not lock to allow for removal of foreign objects. CAUTION: TRIP AND ENTANGLEMENT HAZARD - Do not route cables in a way that they may present a stumbling hazard. Do not route cables underneath the equipment. For safety reasons, all connectors for patient cables and leadwires are designed to prevent inadvertent disconnection, should someone pull on them. For devices installed above the patient, adequate precautions must be taken to prevent them from dropping on the patient. CAUTION: TRIP HAZARD - Route the AC Power cable away from moving parts and out of any potential walking areas minimizing the potential for tripping. An AC power cable caught in moving parts could cause injury to the user and equipment. CAUTION: PERSONAL INJURY - Do not use the treadmill without proper footwear as injury to feet may result. Always wear proper footwear when using the treadmill. CAUTION: EQUIPMENT MALFUNCTION - Before connecting the device to the power line, check that the voltage and frequency ratings of the power line are the same as those indicated on the unit's label. If this is not the case, do not connect the system to the power line until you adjust the unit to match the power source. This equipment is suitable for connection to public mains as defined in CISPR 11. CAUTION: SUPERVISED USE - This equipment is intended for use under the direct supervision of a licensed health care practitioner. Make sure all users are under the direct supervision of a licensed health care practitioner.

Mode of operation
The Elevation motor is not rated for continuous operation. A one minute elevation ON time should be followed by a ten minute OFF time. In normal operation, the treadmill elevation motor operates for much less than 1 minute at a time. All other parts of the treadmill (including the belt drive motor) are rated for continuous operation, and do not have an ON/OFF duty cycle requirement.
EMI/EMC/RF Safety Information This system is designed and tested to comply with applicable regulations regarding EMC and must be installed and put into service according to the EMC information stated in the Electromagnetic Compatibility appendix of the Service and/or Operator’s manual. Changes or modifications to this system not expressly approved by GE Healthcare could cause EMC issues with this or other equipment. Mains power should be a standard commercial or hospital environment. Before installing or using the device or system, be aware of the proximity of known RF sources, such as the following: • Radio and TV stations • Portable and mobile RF communication devices (cell phones, two-way radios) • X-ray, CT, or MRI devices

Introduction
These devices are also possible sources of interference as they may emit higher levels of electromagnetic radiation. WARNING: EQUIPMENT MALFUNCTION/INTERFERENCE - Use of portable phones or other radio frequency (RF) emitting equipment near the system may cause unexpected or adverse operation. Do not use portable phones or other electronic equipment that may emit radio frequency (RF) near this system. WARNING: EQUIPMENT MALFUNCTION/INTERFERENCE - Do not use the equipment or system adjacent to, or stacked with, other equipment. If adjacent or stacked use is necessary, test the equipment or system to verify normal operation in the configuration in which you are using it. WARNING: ACCESSORIES/COMPONENTS - Adding accessories or components, or modifying the medical device or system, may result in increased EMISSIONS or decreased IMMUNITY of the device or system. Use the following resources for more information on EMI/EMC and RF concerns: • The Supplies and Accessories Reference Guide for your system • Qualified GE Healthcare or approved third-party personnel • The Electromagnetic Compatibility appendix in your system service or operator’s manual NOTE: Compliance provides reasonable protection against radio-frequency interference. However, there is no guarantee that interference will not occur in a particular installation. You can tell whether this device or system is causing interference by turning it off. If the interference stops, it was most likely caused by the device or system.
Responsibility of the Manufacturer GE Healthcare is responsible for the safety, reliability, and performance of hardware supplied by GE Healthcare only if the following conditions are met: • Assembly operations, extensions, readjustments, modifications, or repairs are performed by persons authorized by GE Healthcare. • The electrical installation of the room where the device is used complies with the requirements of the appropriate local, state, and other government regulations. • The equipment is used in accordance with the instructions for use.
