3M PCAP: Resetting the Controller

Symptom(s): No Touch, Intermittent Touch, Dead Spots
Affected OS: Windows 10
Prerequisite Software: MT7SDU


1. After downloading the MT7SDU software from the link above, double click the MT7SDU icon.

2. The software will automatically detect your 3M PCAP Controller and launch the configuration utility. If it is not found, please contact TSI Touch Customer Service for further assistance. (Note: Touch will be disabled while the configuration utility is open)

3. To begin the reset process, first click on the Tools button in the menu ribbon and click on Restore Defaults.
