X12+_______________________________________________________________________________
Electromagnetic Compatibility (EMC) Electromagnetic compatibility with surrounding devices should be assessed when using the X12+ Transmitter. An electronic device can either generate or receive electromagnetic interference. Testing for electromagnetic compatibility (EMC) has been performed on the X12+ Transmitter according to the international standard for EMC for medical devices (IEC 60601-1-2). This IEC standard has been adopted in Europe as the European Norm (EN 60601-1-2). The X12+ Transmitter should not be used adjacent to, or stacked on top of other equipment. If the X12+ Transmitter must be used adjacent to or stacked on top of other equipment, verify that the X12+ Transmitter operates in an acceptable manner in the configuration in which it will be used. Fixed, portable, and mobile radio frequency communications equipment can affect the performance of medical equipment. See Table X-4 for recommended separation distances between the radio equipment and the X12+ Transmitter.
Accessories and Cables Warning The use of accessories and cables other than those specified below, may result in increased emissions or decreased immunity of the X12+ Transmitter. Description

Field strengths from fixed RF transmitters, as determined by an electromagnetic site surveya, should be less than the compliance level in each frequency rangeb. Interference may occur in the vicinity of equipment marked with the following symbol:
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radios, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the X12+ Transmitter is used exceeds the applicable RF compliance level above, the X12+ Transmitter should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the X12+ Transmitter. b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [3] V/m.

Metallic and Plastic Parts Cleaning
CAUTION Do not wipe over surfaces of nameplates or labels with abrasive cleaners or materials, as this will eventually wear away the nameplate information. Do not use solvents to clean plastic parts. Wipe metal surfaces with soft, nonabrasive cloth dampened with isopropyl alcohol. Dry surfaces with clean cloth. Wipe surfaces of nameplates and labels with dry cloth.
Exterior Cleaning. Use a damp cloth to clean external covers and the patient cable. Do not use alcohol on the patient cable. Alcohol may damage the insulation of the patient cable..
Interior Visual Inspection Check all connectors for loose, bent or corroded contact points Check wire, harnesses and cables for signs of wear or deterioration. Inspect leads for security of mounting, or deterioration. Check terminals and connections for proper installation, loss or wear. Check the identification nameplate and other decals for legibility. Inspect chassis and covers for warping, bending, surface damage or missing captive hardware. Check all screws and nuts for tightness or signs of stripped or crossed threads. Check for any other form of mechanical damage, which may indicate a failure.
