16 16010-101 Rev. CTroubleshootingFrequently Asked QuestionsQ: The unit will not power up.A: Always ensure the IOPac is charged sufficiently. USE ONLY THE SUPPLIED PALM CHARGER PROVIDED WITHTHE UNIT, or a USB CABLE (such as the one supplied with the IOPac) CONNECTED TO A COMPUTER. Werecommend a minimum charge level of 50%. The IOPac is based on a Palm handheld computer that uses arechargeable battery to maintain stored data and programs. Like similar computers, if the battery becomes too drained itwill not be able to function. To ensure the IOPac is always ready for use, a good guideline is to charge it overnight at leastweekly and to leave it attached to a charger when not in use for longer periods.Q: I have been tapping on the cornea with the probe and I cannot get measurements?A: The IOPac has a unique design that takes multiple measurements very quickly. Just contact the cornea with the probetip and hold it in place until all 8 measurements have been made. The IOPac is not designed to work by tapping.Q: Why can’t I get a reading when I’m checking calibration?A: Calibration normally works best by filling the phantom orifice with water and placing the probe tip against the phantombefore initiating the measurement. Additionally, try shifting the angle of the probe during calibration; the face of probe tipmay not be lying flat on the phantom surface. For the 45 degree probe, it is often more effective to hold the probe by itselbow.Q: I cannot get a reading on an eye?A: The most likely cause of this issue is a loose probe connection. Try pushing on the gold connector on the back of thePachymeter. If that does not work, try unplugging it and checking that both the connector and unit are undamaged andthen reinsert the connector. Also confirm that the patient does not have dry eyes. It may be necessary to place a drop ofartificial tears on the eye before the measurement.Q: What happens if I disrupt the printing by blocking the IR beam or displacing the IOPac?A: The IOPac is fairly tolerant of beam disruption. If an object or the field of view changes and disrupts the printing,readjust the IOPac to have a clear line of sight to the printer’s IR port.Q: The Pachymeter software is hung up and won’t respond. What do I do?A: In rare circumstances it is possible to crash the Palm Operating system. To recover from a system hang, insert anarrow blunt object such as an unfolded paperclip or toothpick into the hole marked ‘reset’ on the back of the unit until itpresses the reset button at the bottom of the hole. The Pachymeter screen should go blank followed by the Palm bootingscreen. This will cause a soft reboot and your database and program should not be effected.Q: How do I locate the Pachymeter software if it does not automatically load on startup?A: To locate the IOPac icon, tap the Home icon at lower-left corner of the screen and look for the IOPac icon. Tap thisHome icon repeatedly to cycle through all program categories until the IOPac icon is found. If this icon still appears to bemissing, tap the upper left corner of the Home screen to activate the menu and select Info. Look for IOPac in the Info list,scrolling down if necessary. If it does not appear in the Info list, try reloading the application using the HotSync feature.Follow the directions in Appendix A of this Manual.Q: The calibration guide hole is dirty, how should I clean it?A: Using a Q-tip or similar soft tipped device dipped in alcohol gently swab the hole. Ensure that the flat calibrationsurface at the bottom of the hole is clean. Be sure not to exert excess force onto the phantom while cleaning.Q: Why does the unit display a reading when not in contact with the patient's eye?A: If the tip of the probe is wet, the unit will measure the thickness of the drop of water on the tip. To avoid this, ensurethe tip is dry after cleaning or disinfecting.
