The type of card reader supplied may vary from time to time. It may be a single card type (SD and MMC cards only) or a multi-card type.

  • Page 43: File Locations For Psanalyzer Data Files

    23.2. File Locations for PSAnalyzer data files The PSAnalyzer application is stored within the internal program memory of the handheld computer. The initialisation file that stores the “last used” settings when the application is terminated is also stored within the internal memory. However, files created by the user (stored traces, set-ups and screens) are stored on a plug-in memory card.

  • Page 44: Cleaning

    In dirty environments or when using a finger to press the screen, it may be advisable to use a Screen Protector to prevent grease or other contaminants from damaging the screen. A Screen Protector reduces the quality of the display somewhat, although this can be minimised by careful application. Some people generate a considerable level of grease from their finger tips, and may find that the screen quickly becomes smeared when regularly touched.

  • Page 45: Resetting The Palm T|X

    Reinstalling or updating the application may require the original memory card supplied with the PSA1301/2701T by TTi. Should this have been lost or erased, it will be necessary to create a duplicate from the support CD supplied by TTi with the product.
