Chapter 1: Getting Started About the system

A license key is required to activate the software. See “Software licensing” on page 90. On occasion, a software upgrade may be required. SonoSite provides a USB device containing the software. One USB device can be used to upgrade multiple systems.

Getting Started

The Edge 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.

Figure 2 System Back Connectors: (1) DC input connector, (2) Battery, (3) I/O connector, and (4) ECG connector

Basic operating steps 1 Attach a transducer. 2 Turn the system on. (For power switch location, see “System controls” on page 5.) 3 Press the PATIENT key, and complete the patient information form. 4 Press an imaging mode key: 2D, M MODE, COLOR, or DOPPLER.

Preparing the system 4

Installing or removing the battery 1

WARNING:

To avoid injury to the operator and to prevent damage to the ultrasound system, inspect the battery for leaks prior to installing.

WARNING:

To avoid data loss and to conduct a safe system shutdown, always keep a battery in the system.

See also “Battery safety” on page 100.

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. 5 Slide the two locking levers outward to secure the battery.

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. 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.

WARNING:

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.

Caution:

Verify that the hospital supply voltage corresponds to the power supply voltage range. See “Electrical specifications” on page 117.

To operate the system using AC power Figure 3 Install the Battery

To remove the battery 1 Disconnect the power supply from the ultrasound system.

1 Connect the DC power cable from the power supply to the connector on the system. See Figure 2 on page 1. Push the cable in firmly to ensure a secure attachment. 2 Connect the AC power cord to the power supply and to a hospital-grade electrical outlet.

Preparing the system

Turning the system on or off Caution:

6 Press the latch down, securing the transducer connector to the system.

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. Getting Started

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.

Connecting transducers 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:

To avoid damaging the transducer connector, do not allow foreign material in the connector.

To connect a transducer 1 Remove the system from the mini-dock (if present), and turn it upside down.

Figure 4 Connect the Transducer

To remove a transducer

2 Pull the transducer latch up, and rotate it clockwise.

1 Pull the transducer latch up, and rotate it clockwise.

3 Align the transducer connector with the connector on the bottom of the system.

2 Pull the transducer connector away from the system.

4 Insert the transducer connector into the system connector. 5 Turn the latch counterclockwise.

Chapter 1: Getting Started

Inserting and removing USB storage devices You can use a USB storage device to import and export various logs and setup configurations and to archive images and clips. 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. See also “Troubleshooting” on page 89. 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:

4

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.

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 22.

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.

On-screen controls The on-screen controls let you make adjustments and select settings. The controls available depend on context. Each control is controlled by the pair of keys below it. Depending on the control, the keys function in one of four ways: Cycle Moves through a list of settings continuously. The upper key cycles upward. The lower key cycles downward. Up-Down Moves through a list of settings, stopping at the top or bottom. The upper key moves upward. The lower 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 key. In forms, you can instead select the control by using the touchpad and the SELECT key. Action Performs an action. You can press either key. Or you can instead select the control by using the touchpad and the SELECT key.
