Conventions Used in This Manual

These conventions are used in this manual:

!All procedures are numbered. You must complete steps in the sequence they are presented to ensure a reliable result.

!Bulleted lists indicate general information about a particular function or procedure. They do not imply a sequential procedure.

!Control names appear in this manual like they appear on the system.

!Menu items or titles appearing on the monitor screen are shown in the manual like they appear on the screen.

!The left side of the system is to your left as you stand in front of the system, facing the system.

!Scanheads and pencil probes both are referred to as scanheads, unless the distinction is important to the meaning of the text.

!“Select” means to place the cursor over an item and press SELECT once.

!“Double-select” means to place the cursor over an item, and quickly press SELECT two times, like double-clicking with a computer mouse. Pressing SELECT too slowly on double select will only highlight an item. Pressing it rapidly will initiate an action.

System Conventions

These conventions are used in the system:

!The software that runs the system uses graphic display elements similar to those used in many personal computers. References to these elements in the software or in the manual are defined in the glossary in the Reference Manual.

!On a menu, protocol, or other display, a highlight bar indicates that the item or name contained within the boundaries of the highlight bar is in the process of being selected. Pressing the SELECT control or other related control actually selects the item, assigns a value to a system parameter, or initiates the action related to the selected item.

!On a menu, an underlined letter indicates that pressing the underlined letter on the system keyboard will have the same effect as choosing the menu item with the trackball and the SELECT control.

!On the system keyboard, pressing the Superkey and another designated key, for example 2D Maps, allows you to quickly change a system parameter without using the menu on which the parameter appears.

1--2	HDI 5000 Reference Manual 4703-0027-03

!Pressing a key or control the first time initiates a mode change, function, or operation, or changes the value of a system parameter. Pressing the same key or control a second time resumes a previous mode or system parameter, cycles to the next setting, or ends the function or operation. All MENU controls work this way, and it can be quicker to press the MENU control than to select Close, especially to exit a submenu.

!On a menu, protocol, or other display, text that is lighter in color than the other text on the display indicates that the item or name contained within the boundaries is not available for selection in that menu, protocol, or display.

!	A	or	indicates an option or alternative for selection.
!	A	or	indicates that an option or alternative has been selected.

!Selecting Close from a menu or display removes the menu or display from the screen.

!Selecting + or -- increases or decreases the value of the parameter.

!An ellipsis ... on a menu indicates that a submenu is available from the selection.

!To highlight a menu, protocol, or other display item, use the trackball to move the cursor to the particular item.

!To enter text into a text field, use the keyboard.

!The softkeys, located on the lower right of the control panel, assume functions based on your control selections. For example, pressing VCR CTRL results in the softkeys assuming these VCR control functions: PLAY, PAUSE, STOP, FF (Fast Forward), and REWIND.

Controls

This section contains information on all system controls, regardless of system configuration. It is arranged as follows:

!Monitor Module

!Control Module

!Main Chassis

For specific information about the VCR controls, the hardcopy device controls, network devices, or other peripherals see the manufacturer’s instructions for those devices.

Monitor Module

The controls on the video monitor affect brightness, contrast, background color, and the brightness of the lightbar (Figure 2--1). When a control is pressed, an on-screen display provides information about the relative level of brightness, contrast, background color, or lightbar brightness (some monitors do not have an on-screen display for lightbar brightness). The on-screen display remains on until the timeout period ends, which is about three seconds after the control is last pressed. To reset the monitor module control setting to the default setting, press the increase and decrease controls simultaneously.

Before imaging with the system, wait about 20 minutes after turning the system on. The system can be used, but the video monitor requires a warm-up period. This warm-up period is necessary to ensure consistent image quality.

Brightness adjusts the light output of the entire display.

Contrast adjusts the difference in light output between the light and dark parts of the display.

Background Color selects the background color of the display.

Lightbar adjusts the brightness of the lightbar, which illuminates the control panel.

CAUTION
		Maintaining a very high display-contrast level can damage your screen. Do not
		use high-contrast settings for an extended period of time.

HDI 5000 Reference Manual 4703-0027-03

Controls

Monitor Adjustment

Optimal brightness and contrast settings can vary in different lighting conditions and even from person to person. To minimize incorrect settings when there are multiple users, it is best to keep the monitor set to the default values.

"To display the current monitor control settings:

Press a background color, brightness, or contrast monitor control to display the current control setting (Figure 2--1). Settings are displayed for approximately 2 seconds. The lightbar brightness varies, but there is no on-screen display.

"To adjust the monitor contrast and brightness to a default setting:

1.Simultaneously press the up and down contrast controls twice to set the monitor to the factory default.

2.Simultaneously press the up and down brightness controls twice to set the monitor to the factory default.

3.Simultaneously press the lightbar controls twice to set the monitor to the factory default.

4.Press the background color control to select the background color on the display. Color 1 is the factory default option.

5.Press the lightbar brightness control to adjust control panel illumination.

Monitor Latches

The monitor latch has been designed to avoid inadvertent unlatching when you place items in the tray under the monitor. The handle requires a tool (small screwdriver or metal rod) to unlatch it.

To unlatch the monitor, insert the tool in the center of the latch handle. Push down to rotate the latch handle to the down position. Slide the handle toward the rear of the monitor to unlock the latch. When the latch mechanism is unlocked, the latch handle hangs down (Figure 2--2), and then the monitor can be removed from the system.

The monitor latch secures the monitor to the system. It is not a tilt/swivel latch. The latch must remain in the locked position during normal system operation. Unlock the latch only to remove the monitor from the system. The latch is shown in Figure 2--2.

WARNING The monitor can fall off of the system if the latches are not locked.

Changes the sample volume size. The available settings are as follows for all scanheads, except the D2 TC pencil probe: 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0 5.0, 7.5, 10.0, 12.5, and 15.0 mm. The D2 TC pencil probe has the following settings: 1.5, 2.0, 3.0, 5.0, 10.0, 15.0, and 25.0 mm.

TDI (Tissue Doppler Imaging)

With a compatible scanhead, in 2D Color, Color M-mode, and pulsed-wave Doppler, activates the TDI display.

TGC Slide Controls

Each slide control adjusts the receiver gain for the 2D and M-mode image displays at a particular depth. When the slide controls are set in the center, a default curve is assigned that gives a uniform gain throughout the image display. The TGC curve on the screen does not directly correlate to the TGC slide control positions. Color, Doppler, and Power imaging are not affected by the TGC slide controls; these modes assume a flat TGC curve.

TIMERS

With the DVS option, controls three timers used in freeform capture and acquisition protocols.

TOOLBAR

With the DVS option, displays the image-review toolbar. Press a second time to remove the image review toolbar.

Keyboard

The keyboard contains special function keys, alphanumeric keys, annotation keys, and superkeys (Figure 2--5). With the special function keys, you can perform specific functions, such as choosing a scanhead or changing setups. The alphanumeric keys are used with the annotation keys to enter text. The superkeys are used with the Superkey (there are two, for convenience) to more quickly adjust various image display processing or format characteristics.

The superkeys, labeled with small text below the characters, allow quicker adjustments than if you use the corresponding MENU controls. Using the superkeys results in an immediate change to the setting. A five-second prompt appears above the image display to indicate the new setting. The image display and the image information is slso updated to reflect the new setting.

On a menu, an underlined letter is a keyboard equivalent. When you press a keyboard equivalent, the result is the same as selecting the menu item.

The following paragraphs describe the functions of each of the keys on the keyboard that have special functions. Alphanumeric keys that do not have special functions are simply used for text entry, and they are not listed or explained in the following.
