Getting Started
The M-Turbo ultrasound system is a portable, software-controlled device using all-digital architecture. The system has multiple configurations and feature sets used to acquire and display high-resolution, real-time ultrasound images. Features available on your system depend on system configuration, transducer, and exam type.

Installing or removing the battery 2
Figure 1 System Front Features: (1) Control panel, (2) Handle, (3) Display, (4) USB ports for storage, updates, importing, and exporting
WARNING:
To avoid injury to the operator and to prevent damage to the ultrasound system, inspect the battery for leaks prior to installing. To avoid data loss and to conduct a safe system shutdown, always keep a battery in the system.
Chapter 1: Getting Started
1
To install the battery 1 Disconnect the power supply from the ultrasound system. 2 Remove the system from the mini-dock (if present) and turn it upside down. 3 Place the battery into the battery compartment, at a slight angle. See Figure 3. 4 Slide the battery forward until it locks into place.
Locking levers
5 Push down on the two locking levers to secure the battery.
To remove the battery 1 Disconnect the power supply from the ultrasound system. 2 Remove the system from the mini-dock (if present) and turn it upside down. 3 Pull up the two locking levers. 4 Slide the battery back. 5 Lift the battery from the compartment.
Using AC power and charging the battery The battery charges when the system is connected to the AC power supply. A fully discharged battery recharges in less than five hours. The system can run on AC power and charge the battery if AC power is connected to the system directly, to a mini-dock, or to a docking system.
Figure 3 Install the Battery
2
Preparing the system
The system can run on battery power for up to two hours, depending on the imaging mode and the display brightness. When running on battery power, the system may not restart if the battery is low. To continue, connect the system to AC power.
Connecting transducers The equipment shall be connected to a center-tapped single phase supply circuit when users in the United States connect the equipment to a 240V supply system.
WARNING:
To avoid injury to the patient, do not place the connector on the patient. Operate the ultrasound system in a docking system or on a flat hard surface to allow air flow past the connector.
Caution:
Verify that the hospital supply voltage corresponds to the power supply voltage range. See “Electrical” on page 160.
Caution:
To avoid damaging the transducer connector, do not allow foreign material in the connector.
Getting Started
WARNING:
To operate the system using AC power 1 Connect the DC power cable from the power supply to the connector on the system. See Figure 2 on page 1. 2 Connect the AC power cord to the power supply and to a hospital-grade electrical outlet.
Turning the system on or off Caution:
Do not use the system if an error message appears on the display. Note the error code and turn off the system. Call SonoSite or your local representative.
To turn the system on or off Press the power switch. (See “System
controls” on page 5.)
To wake up the system To conserve battery life while the system is on, the system goes into sleep mode if the lid is closed or if the system is untouched for a preset time. To adjust the time for sleep delay, see “Audio, Battery setup” on page 19. Press a key, touch the touchpad, or open the
lid. Figure 4 Connect the Transducer
Chapter 1: Getting Started
3
To connect a transducer 1 Remove the system from the mini-dock (if present), and turn it upside down.
WARNING:
To avoid damaging the USB storage device and losing patient data from it, observe the following: • Do not remove the USB storage device or turn off the ultrasound system while the system is exporting. • Do not bump or otherwise apply pressure to the USB storage device while it is in a USB port on the ultrasound system. The connector could break.
Caution:
If the USB icon does not appear in the system status area on-screen, the USB storage device may be defective or password-protected. Turn the system off and replace the device.
2 Pull the transducer latch up, and rotate it clockwise. 3 Align the transducer connector with the connector on the bottom of the system. 4 Insert the transducer connector into the system connector. 5 Turn the latch counterclockwise. 6 Press the latch down, securing the transducer connector to the system.
To remove a transducer 1 Pull the transducer latch up, and rotate it clockwise. 2 Pull the transducer connector away from the system.
Inserting and removing USB storage devices Images and clips are saved to internal storage and are organized in a sortable patient list. You can archive the images and clips from the ultrasound system to a PC using a USB storage device or Ethernet connection. Although the images and clips cannot be viewed from a USB storage device on the ultrasound system, you can remove the device and view them on your PC. There are two USB ports on the system, and one on the mini-dock. For additional USB ports, you can connect a USB hub into any USB port. Note: The system does not support password- protected USB storage devices. Make sure that the USB storage device you use does not have password protection enabled.
4
Preparing the system
To insert a USB storage device Insert the USB storage device into any USB
port on the system or mini-dock. See Figure 1 on page 1. The USB storage device is ready when the USB icon appears. To view information about the device, see “USB Devices setup” on page 23.
To remove a USB storage device Removing the USB storage device while the system is exporting to it may cause the exported files to be corrupted or incomplete. 1 Wait five seconds after the USB animation stops. 2 Remove the USB storage device from the port.

General interaction Touchpad and cursor Use the touchpad to adjust and move objects on-screen. The touchpad controls caliper position, CPD or Color box position and size, the cursor, and more. The arrow keys control much of the same functionality as the touchpad. The cursor appears in the setup pages, the patient information form, and patient report. You control the cursor through the touchpad. For example, in the patient information form, place the cursor over the last name field and press the SELECT key to activate that field. Additionally, you can use the cursor to select check boxes and items in lists.
Cycle Moves through a list of settings continuously. The upper control key cycles upward. The lower control key cycles downward. Up-Down Moves through a list of settings, stopping at the top or bottom. The upper control key moves upward. The lower control key moves downward. By default, a beep sounds when you reach either end of the range. (See “Audio, Battery setup” on page 19.) On-Off Turns a feature on or off. You can press either control key. In forms, you can instead select the option by using the touchpad and the SELECT key. Action Performs an action. You can press either control key. Or you can instead select the option by using the touchpad and the SELECT key.

Caution:
To avoid damage to the transducer, use only gels recommended by SonoSite. Using gels other than the one recommended by SonoSite can damage the transducer and void the warranty. If you have questions about gel compatibility, contact SonoSite or your local representative. SonoSite recommends that you clean transducers after each use. See “Cleaning and disinfecting transducers” on page 76.
1 Select the field, and then select Symbols. 2 Select the desired symbol or character. You can also press the keys on the keyboard. 3 Select OK.
Acoustic coupling gel must be used during exams. Although most gels provide suitable acoustic coupling, some gels are incompatible with some transducer materials. SonoSite recommends Aquasonic® gel and provides a sample with the system. For general use, apply a liberal amount of gel between the transducer and the body. For invasive or surgical use, apply a transducer sheath.
10
Preparing transducers
4 Select the Videos tab. WARNING:
To apply a transducer sheath SonoSite recommends the use of market-cleared, transducer sheaths for intracavitary or surgical applications.To lessen the risk of contamination, apply the sheath only when you are ready to perform the procedure. 1 Place gel inside the sheath. 2 Insert the transducer into the sheath. 3 Pull the sheath over the transducer and cable until the sheath is fully extended. 4 Secure the sheath using the bands supplied with the sheath. 5 Check for and eliminate bubbles between the face of the transducer and the sheath. Bubbles between the face of the transducer and the sheath may affect the ultrasound image. 6 Inspect the sheath to ensure that there are no holes or tears.
