7-1-1 Purpose of Chapter 7
This section describes how to setup and run the tools and software that help maintain image quality and 
system operation. Basic host, system, and board leve l diagnostics are run whenever power is applied. 
Some Service Tools may be run at the application level.
NOTE: Be sure to disable ECG function  before performing Diagnostic function.
NOTE: Make sure that convex or linear probe is connec ted before the system starts. (sector probe is not 
applicable for the service diagnostics)

Gathering Trouble Data
7-2-1 Overview
There may be a time when it would be advantageous to  capture trouble images and system data (logs) 
for acquisition through remote diagnos tics (InSite) or to be sent back to the manufacturer for analysis. 
There are different options to acquire this data that would give different results. 
7-2-2 Collect Vital  System Information
The following information is necessary in order to pr operly analyze data or images being reported as a 
malfunction or being returned to the manufacturer:
- Product Name = LOGIQ™ P5/A5/A5Pro
From the  Utility>System>About  screen:
Applications Software - Software Version
- Software Part Number
System Image Software
- Image Part Number
- Image Date

7-2-3 Collect a Trouble Image with Logs
If the system should malfunction, press the Alt-D keys simultaneously. This will collect a screen capture 
of the image monitor, system presets and the following logs:
- Keyboard Shadow Log
- Error Logs
-Crash Log
- Power Supply
- Temperature
NOTE: Power Supply and Temperature logs are no t currently being updated by the LOGIQ™ P5/A5/
A5Pro.
This Alt-D function is  available at all times. 
When Alt-D is pressed, a menu  box appears that allows for:
- A place to enter a description of the problem
- A choice to store to a pre-formatted CD-R/DVD, USB or Network storage.
The subsequent file is compressed and time stamped.  The screen capture is a bitmap which eliminates 
the possibility of artifacts from compression. Figure 7-1   ALT-D Dialog Box

Screen Captures
There may be times when the customer  or field engineer will want to capture a presentation on the 
screen so it may be recovered by the OnLine Center  through InSite. This is accomplished by first saving 
the image(s) to the clipboard using a Print Key.
The P2 key is the factory default print key to a ccomplish a secondary screen capture. However, the 
default is for the video area only or the customer  may have customized the P2 Key function. Therefore, 
screen capture should involve the following steps:
1.) Check and record any custom settings for the Print2 button.
2.) Set the Print2 button to Whole Screen, Secondary Capture.
3.) Capture the required screens to the Hard Drive or CD-R / DVD-R.
4.) Restore the Print2 button  to it’s original settings.
7-3-1 Check and Record  the P2 Key Function
Check the function of the Print2 Key in the event that the customer may have made some custom 
settings.
1.) Select Utilit y from the FrontPanel.
2.) Select Connectivity  from the Menu.
3.) Select the Buttons  tab on the Connectivity screen.
4.) In the  Button field, select Print2.
The Connectivity/Buttons Screen will be disp layed like the one shown in Figure 7-2.
P2 is the factory default Screen C apture Key. If it is not set to Whole Screen or Screen Capture, as 
shown in Figure 7-2, proceed to step 5 to record the customer’s custom settings. Figure 7-2   Buttons Set Up Screen

* Image Frames
* Capture Area
* Compression
6.) In the “Printflow View”, record the prin t flow associated with the Print2 Button.
7-3-2 Setting the P2 K ey to Screen Capture
If the P2 Key is not set to screen capture:
1.) While on the Connectivity screen, with the Butt ons tab displayed, go to the drop down selection 
menu in the  Destinations  section.
2.) Ensure that Capture Area is set to Whol e Screen, secondary Capture and None Image 
Compression.
3.) The P2 Key should now be set up for whole screen capture, sending the screens to the image  buffer (clipboard).

Diagnostics
As described in   - Components and Functions (Theory) , the service platform uses a web-based user 
interface (UI) to provide access to common service components.
The Diagnostic home page displays a listing of test  categories consisting of Common Diagnostics, and 
LOGIQ™ P5/A5/A5Pro Diagnostics. Ex pand the desired main category to select groups or individual 
tests.
