1. Verify that the WT is properly connected to the laptop. The USB plug from the WT should
be inserted into one of the laptop’s USB ports. Figure 2.4 shows the indicator for proper
connection.
2. Verify that the patient and IPG are within 1 m of the WT.
3. Verify that the programming problem is not a result of EMI from nearby electrical or
magnetic equipment. Examples of possible sources of EMI are laptop displays, portable
telephones, fluorescent lighting, OR lights, and magnetic pads for surgical instruments.
4. Verify that the programming problem is not a result of the IPG or WT being placed on a
metal table.
Failure of the IPG and WT to clearly communicate with each other at any time can be attributed
to several factors, such as:
• WT not properly connected to laptop
• Programming in the presence of an EMI signal (e.g., OR lights, the programming laptop itself,
other computers, or other medical devices). This can be difficult or impossible, but problems
can usually be resolved by repositioning the patient, the WT, or the EMI source.
• Movement of the patient away from the WT during communication
• Proximity of the IPG or WT to a metal table or large metal object
• Presence of metal barriers between the IPG and WT
• IPG battery at end of life (EOL)
• Software (SAPS) needing to be restarted by restarting computer
• Defective WT
• Defective laptop
• Defective IPG
Communication problems are often intermittent and are rarely related to the IPG. The
surrounding environment typically causes these problems.
Restarting the laptop solves most communication and other system issues that are not
connection related.
13.2.2 Unable to Initiate Communication
In certain instances, the user may be unable to communicate with the IPG. After trying all other
remedies (verifying all connections, restarting the computer, etc.), please contact
MicroTransponder for assistance in resetting the IPG. Contact information is provided in
Section 18: Information and Support.
