Programmer Basics
Positioning and Using the Programming Head
Positioning and Using the Programming Head
In many of the procedures described in the following chapters,
you will be directed to position the programming head over the
patient’s implanted device.
When to Position the Programming Head
You must position the programming head over the patient’s
implanted device whenever a procedure initiates communication
between the programmer and the implanted device. Examples
are:
■
At the start of a patient session when you select the
[
Auto-Identify] or [Start] button. The programmer
automatically initiates an interrogation that takes a number of
seconds to complete.
■
Prior to executing any command that results in a telemetry or
programming transmission.
■
To view or record Marker Channel or EGM telemetry.
Caution: Do not position the programming head over an
implanted device during electrocautery or defibrillation
procedures.
InSync® III Model 8042 Device Programming Guide 1-7
Programmer Basics
Positioning and Using the Programming Head
How to Position the Programming Head
♦
The programming head must be properly positioned as described
below. An incorrectly positioned programming head can result in
the failure of a transmitted command and the loss of telemetry.
1. Hold the programming head directly against the patient’s
skin with the face of the programming head parallel to the
implanted device.
Figure 1-9. Positioning the Programming Head
2. Position the programming head so that the amber light in
the light array goes out and one or more of the green lights
come on. Move the head a little in each direction to find the
position that lights the greatest number of green lights. This
is the optimum position.

Programmer Basics
Positioning and Using the Programming Head
Effect of the Programming Head on Operation of the Implanted Device
If model selection and application (software) loading are
complete, positioning the programming head over an implanted
InSync III device does not put the device in the magnet mode of
operation, as is the case with previous device models. The
programmer automatically sends a Cancel Magnet command to
the implanted device, which causes it to continue to operate as
programmed.
An exception to this operation can occur if the programming head
does not establish a telemetry link with the implanted device
(because of strong electrical interference or because the
programming head is improperly positioned). In such cases,
positioning the programming head would result in magnet mode
operation until a telemetry link is established. You can easily
verify the present pacing mode by observing the Status Line at the
top of the screen.
The present pacing mode
shows in the status bar at
the top of the screen.
Operation of the implanted device returns to its programmed
state about 2 seconds after you remove the programming head
from its position over the device.
InSync® III Model 8042 Device Programming Guide 1-9
Programmer Basics
Positioning and Using the Programming Head
Observing Magnet Mode Operation
To observe Magnet mode operation during a patient session, you
must conduct the Magnet test described in Chapter 2. Initiating
the Magnet test results in a Threshold Margin Test (TMT) and
causes the implanted device to operate in the Magnet mode.
Note: Between patient sessions before you select the device
model, positioning the programming head over the implanted
device will result in magnet mode operation.
Alternative PROGRAM and
INTERROGATE Buttons
To initiate the Program and Interrogate commands, you have the
option to use the on-screen [

Programmer Basics
Positioning and Using the Programming Head
Automatic Interrogation at the Start of a Session
At the start of a session when you select [Start] or [Auto Identify],
the programmer automatically interrogates the patient’s
implanted device. For this process, you must position the
programming head and hold it steady in place until the
interrogation is complete.
At the bottom center of the screen, an indicator shows the progress
of the interrogation. Because this interrogation retrieves
parameter information and a portion of the diagnostic data stored
in the implanted device, the process may take about one minute.

Programmer Basics
About the Display Screen
The Command Bar
The bar at the bottom of the screen always shows the command
buttons for programming “emergency” parameters settings,
interrogating the implanted device, and ending the patient
session.
For complete information on these functions, see “Programming
Emergency Parameters” on page 1-20, “Interrogating the
Implanted Device” on page 2-15, and “Ending a Patient Session”
on page 2-34.
The Task Area
The portion of screen between the live rhythm monitor window at
the top and the command bar at the bottom changes according to
the task or function you select. The example in Figure 1-12 shows
the Therapy Parameters screen for programming device
parameter settings. This task area would appear much different if
you selected, for example, the Threshold Test Setup screen.
Active Fields
Unshaded areas, or boxes, appearing in the task area are “active
fields” that respond to the stylus.
Active fields show as
unshaded areas on
1-14 InSync® III Model 8042 Device Programming Guide
the screen.
Selecting a value, word, name, or phrase that appears in an active
field opens a menu or window of alternative options for whatever
is represented in that field.
Selecting an active field
opens a menu or window
of alternative options, or
in some cases, an
on-screen keyboard.
Programmer Basics
About the Display Screen
For example, touching the mode value “DDD” in the Mode field
with the tip of the stylus opens a window of mode options.
Selecting any one of these options replaces the original DDD value
with the selected one, which becomes a “pending” value.
Selecting some fields (those with terms ending in an ellipsis, such
as “Rate Response...”) open a window displaying additional
fields. Some fields that require entry of information, such as
patient data, open an on-screen keyboard. How to use this
keyboard is described later in this section.
Buttons having a less
distinct shaded label
are not presently active.
Buttons
Buttons like those shown below let you operate the programmer
using the stylus. You can “press” a button by touching it with the
tip of the stylus.
Buttons may directly execute a command, such as the [
button, or they may open a window that prompts another action.
Usually such buttons have a label ending with an ellipsis, such as
the [
Save...] or [Get...] buttons shown above.

Programmer Basics
About the Display Screen
Buttons
Icons
A procedure may instruct you to “press and hold” a button. In
such cases you should touch the tip of the stylus to the button and
continue to maintain pressure against the button until it is time to
“release” the button.
The Tool Palette
The collection of buttons and icons along the edge of the screen is
referred to as the “tool palette.” These are the controls you will use
to choose the task or function screen you want displayed. Once
you have started a patient session, the tool palette is always
displayed, making it quick and easy to move to the desired task or
function.
Each of the icons acts like a button. To select an icon, touch the icon
with the stylus. The “<” symbol adjacent to three of the icons
indicates that selecting one of these icons opens a menu of related
options. The icons without the < symbol directly open a task
screen.
Refer to Table 2-2 on page 2-11 for a brief explanation of the
purpose of each button and icon in the tool palette.
Note: If the programmer is operating in the Demo mode, the
Session icon is replaced with the Demo icon.
