M2540-92000-01 A M2540 Ultrasound System Field Service Manual Transmit Power (Acoustical) Page 27 Safety: Transmit Power (Acoustical) Acoustic output, expressed as an index, is displayed on the screen to allow the best possible diagnostic image with minimal power output.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual Page 28 Safety: AIUM/NEMA Output Display Standard • Reduce exposure time, independent of acoustic index value. • Use techniques that let you collect clinical data quickly and end the examination promptly. • Select a transducer that provides good resolution and focal depth for the region of interest. Then use the imaging controls to fine-tune image resolution.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual Page 29 Safety: AIUM/NEMA Output Display Standard NOTE The power index displayed on the screen depends on the preset type, the active transducer type, the imaging mode, and the selected power index. Any of the four power indices is selectable for display at any time, using the power index setting in the System Setup menu.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual Page 30 Safety: Explosive Hazards When TIC is Displayed With Normal Setting If none of the conditions in “When MI is Displayed With the Normal Setting” on page 29 exist, a transcranial preset is active, and any of the following conditions exist, TIS displays: • Color is turned on. • Angio is turned on. • MMode Trace is the active imaging mode. • Doppler Spectral is the active imaging mode (with 2D Live off).
M2540-92000-01 A M2540 Ultrasound System Field Service Manual • When using the imaging system in the operating room, do not switch system power on or off. Be sure system power is on before the operation starts, and leave it on for the duration of the procedure. WARNING Do not use the foot switch in the operating room.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual Glutaraldehyde Exposure Page 32 Safety: Glutaraldehyde Exposure The United States Occupational Safety and Health Administration (OSHA) has issued a regulation dealing with levels of acceptable glutaraldehyde exposure in the working environment. Philips does not sell glutaraldehyde-based disinfectants with its products. However, this type of disinfectant is recommended for disinfection of transesophageal (TEE) or endocavity transducers.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual Page 33 Safety: Moving the System When Moving the System This system is equipped with a front handle and brakes on the front wheels. WARNING Never strap or secure the system at any point above the peripheral tray. Always use the handle at the front of the cart to move the system from place to place. NOTE Use caution and follow these steps when moving the system from patient to patient. 1. Unlock the wheel locks before moving the system. 2.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual Page 34 Safety: Moving the System WARNING Use care when tilting the system for an incline. The amount of incline allowable to prevent tip-over is 10 degrees. Moving the system over a roadside curb or other small but steep incline can cause the system to exceed 10 degrees of incline.

M2540-92000-01 A M2540 Ultrasound System Field Service Manual Electrosurgical Units Page 37 Safety: Electrosurgical Units Electrosurgical units (ESUs) and other devices intentionally introduce radio frequency electromagnetic fields or currents into patients. Because imaging ultrasound frequencies are also in the radio frequency range, ultrasound transducer circuits are susceptible to radio frequency interference.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual 4 Overview Page 38 Theory of Operation: Overview Theory of Operation This section provides a technical overview of system functions. The discussion focuses on the main functions and features of the system’s PC, circuit boards, and power distribution. Main system functions are also shown in the functional block diagrams at the end of this section.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual Page 39 Theory of Operation: Internal PC Internal PC The M2540A uses an internal PC to coordinate and perform many of the functions that required dedicated circuit boards in earlier ultrasound systems. The power button on the front of the PC is the system power switch. Turning on the PC starts the ultrasound system.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual Page 40 Theory of Operation: TR Boards VCR-Option Components in the PC The VCR option includes several cards inside the PC and an adapter that connects to the SVGA output of the PC’s graphics adapter board. See Figure 4-1 on page 48 for a detailed representation of how the VCR option’s components function in the ultrasound system.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual Page 41 Theory of Operation: TR Boards plugs into the distribution board. The two boards form electronic beams of the transmit and receive signals. Each TR board contains 64 transmitters and 32 preamps multiplexed into 64 receive channels. This allows multiplexing the system’s 64 active channels into 128 element arrays.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual BPAP Board Page 42 Theory of Operation: BPAP Board The beam processor/acoustic processor (BPAP) board contains two processors.

This Itransducer is still fairly low unless its sheath is compromised.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual Page 57 Theory of Operation: Transducer Safety Testing: Test Setup and Theory Imposing an open neutral condition prevents all system current from flowing. This creates a higher potential for leakage current Ichassis. Most flows safely through the ground wire; some flows through the transducer. This Itransducer is still fairly low, unless the chassis is not properly grounded.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual Page 58 Theory of Operation: Transducer Safety Testing: Test Setup and Theory • If the transducer sheath is compromised, its resistance is close to that of the ground wire. Transducer leakage current equaling 80% or more of ground wire leakage current indicates a fault or break in the transducer insulation.
