System Data LOGIQ 5 Basic User Manual 18-7 Direction 2300002-100 Rev. 2 Clinical Measurement Accuracy Basic Measurements The following information is intended to provide guidance to the user in determining the amount of variation or measurement error that should be considered when performing clinical measurements with this equipment. Error can be contributed by equipment limitations and improper user technique. Be sure to follow all measurement instructions and develop uniform measurement techniques among all users to minimize the potential operator error. Also, in order to detect possible equipment malfunctions that could affect measurement accuracy, a quality assurance (QA) plan should be established for the equipment that includes routine accuracy checks with tissue mimicking phantoms. Please be advised that all distance and Doppler related measurements through tissue are dependent upon the propagation velocity of sound within the tissue. The propagation velocity usually varies with the type of tissue, but an average velocity for soft tissue is assumed. This equipment is designed for, and the accuracy statements listed on are based on, an assumed average velocity of 1540 m/s. The percent accuracy when stated applies to the measurement obtained (not the full scale range). Where the accuracy is stated as a percent with a fixed value, the expected inaccuracy is the greater of the two.

System Data LOGIQ 5 Basic User Manual 18-9 Direction 2300002-100 Rev. 2 Clinical Calculation Accuracy Estimate the overall inaccuracy of a combined measurement and calculation by including the stated inaccuracy from the basic measurement accuracy statements. Calculation formulas and databases are provided as a tool to assist the user, but should not be considered an undisputed database, in making a clinical diagnosis. The user is encouraged to research the literature and judge the equipment capabilities on an ongoing basis in order to assess its utility as a clinical tool. CAUTIONDiagnostic errors may result from the inappropriate use of clinical calculations. Review the referenced source of the stated formula or method to become familiar with the intended uses and possible limitations of the calculation.
User Maintenance 18-10 LOGIQ 5 Basic User Manual Direction 2300002-100 Rev. 2 System Care and Maintenance Overview Refer to Section 10 of the LOGIQ 5 Service Manual for any additional maintenance guidance. Contact the local Service Representative for parts or periodic maintenance inspections. Inspecting the System Examine the following on a monthly basis: • Connectors on cables for any mechanical defects. • Entire length of electrical and power cables for cuts or abrasions. • Equipment for loose or missing hardware. • Control panel and keyboard for defects. • Casters for proper locking operation. CAUTIONTo avoid electrical shock hazard, do not remove panels or covers from console. This servicing must be performed by qualified service personnel. Failure to do so could cause serious injury. Biological HazardIf any defects are observed or malfunctions occur, do not operate the equipment but inform a qualified service person. Contact a Service Representative for information.
System Care and Maintenance LOGIQ 5 Basic User Manual 18-11 Direction 2300002-100 Rev. 2 Weekly Maintenance The system requires weekly care and maintenance to function safely and properly. Clean the following: • Monitor • Operator control panel • Footswitch • Video Cassette Recorder (VCR) • Video Page Printer Failure to perform required maintenance may result in unnecessary service calls.
User Maintenance 18-12 LOGIQ 5 Basic User Manual Direction 2300002-100 Rev. 2 Cleaning the system Prior to cleaning any part of the system: 1. Turn off the system power. If possible, disconnect the power cord. See ‘Power Off’ for more information. System Cabinet To clean the system cabinet: 1. Moisten a soft, non-abrasive folded cloth with a mild, general purpose, non-abrasive soap and water solution. 2. Moisten a soft, non-abrasive folded cloth. 3. Wipe down the top, front, back, and both sides of the system cabinet. NOTE: Do not spray any liquid directly into the unit. Monitor To clean the monitor face: Use a soft, folded cloth and a glass cleaner solution. Apply the glass cleaner to the cloth. Gently wipe the monitor face. Do NOT use a glass cleaner that has a hydrocarbon base (such as Benzene, Methyl Alcohol or Methyl Ethyl Ketone) on monitors with the filter (anti-glare shield). Prolonged use of such cleaners will damage the filter (anti-glare shield). Hard rubbing will also damage the filter. NOTE: When cleaning the monitor, make sure not to scratch the monitor. Operator Controls To clean the operator control panel: 1. Moisten a soft, non-abrasive folded cloth with a mild, general purpose, non-abrasive soap and water solution. 2. Wipe down operator control panel. 3. Use a cotton swab to clean around keys or controls. Use a toothpick to remove solids from between keys and controls. NOTE: When cleaning the operator control panel, make sure not to spill or spray any liquid on the controls, into the system cabinet, or in the probe connection receptacle.

Moisten a soft, non-abrasive folded cloth with a mild, general purpose, non-abrasive soap and water solution. 2. Wipe the external surfaces of the unit then dry with a soft, clean, cloth. VCR To clean the VCR: 1. Turn off the VCR power. If possible, disconnect the power cord. 2. Wipe the external surfaces of the unit with a soft, clean, dry cloth. NOTE: Do not use a wet cloth or any cleaning fluid because it may enter and damage the unit. 1. Clean the record and playback heads with a soft, non- abrasive cleaning system, according to the manufacturers instructions. For more information, see the VCRs Operator Manual.
