Physician’s Manual — VNS Therapy Programming Software (8.1)



To select a button or field, tap it with the stylus.



Some information can be entered with a “soft” or “on-screen”
keyboard (an example of the soft keyboard is shown at the bottom of
Figure 27 on page 44). To maximize (enable) or minimize (disable) the
soft keyboard, tap the keyboard icon at the lower right-hand corner of
the screen. You can type letters or numbers by tapping them with the
stylus.



When a selection requires communication with the Pulse Generator, a
message will appear prompting you to hold the Programming Wand
over the Pulse Generator.



When a button is selected, a border will appear around the button (as
on the

Interrogate Device

button in Figure 1 on page 12).



To return to a previous screen, tap

Menu

or

Exit

.



A list of symbols is found in the front of this manual.



A glossary is found in the back of this manual.



The words ON and OFF appear in all capital letters only when they
refer to VNS stimulation.



References to Model 102 include both Models 102 and 102R.



For more information, see “Troubleshooting ” on page 61.

1.6.

Communication Signals

Four rapid,

ascending

musical tones and a screen message signal the

successful completion of an interrogation or programming operation.

Four rapid,

descending

musical tones and a screen message signal a

warning or a failed operation.

The DATA/RCVD indicator on the Programming Wand lights up during a
successful programming operation or interrogation.

Caution:

If the Procedure Failed message appears on the screen,

check both the connection between the handheld computer and the
Programming Wand and the positioning of the Programming Wand in
relation to the Pulse Generator (see the physician’s manual for the
Programming Wand). If you continue to have communication
problems, change the battery in the Programming Wand.

Caution:

The DATA/RCVD indicator on the Programming Wand may

also light up or flicker in the presence of electromagnetic interference
(EMI) or noise. Information on how to detect EMI is provided in the
physician’s manual for the Programming Wand, sections entitled
Understanding the Indicator Lights and Troubleshooting. If the
presence of EMI or noise is suspected, you must verify that the
programming or interrogation occurred successfully by reviewing the
PARAMETER Screen shown in Figure 3 on page 15.
