!   CLEANING
                           The exterior of the probe and cable should be cleaned only using
                           a soft cloth moistened with water or isopropyl alcohol. Abrasive
                           agents, strong detergents, or other solvents may damage the
                           probe. Always ensure that the input receptacles are free of debris
                           before connecting accessories.
    CALIBRATION INTERVAL
                           To guarantee accurate performance, you should have the probe
                           calibrated every 12 months. Avoid exposing the probe to extreme
                           mechanical shock and excessive bending of the cable because
                           these may alter the calibration.
    SERVICE STRATEGY
                           The AP034 circuits utilize fine pitch surface mount devices; it is,
                           therefore, impractical to attempt repair in the field. Defective
                           probes must be returned to a LeCroy service facility for diagnosis
                           and exchange. A defective probe under warranty will be replaced
                           with a factory refurbished probe. A probe that is not under
                           warranty can be exchanged for a factory refurbished probe. A
                           modest fee is charged for this service. The defective probe must
                           be returned in order to receive credit for the probe core.
    TROUBLESHOOTING
                           If the probe is not operating properly, the problem may be the
                           way in which it is used. Before assuming the probe is defective,
                           perform the following troubleshooting procedures.
    A. Trace Off Scale
                           This is typically caused by improper offset setting, or by an input
                           signal that exceeds the probe differential or common mode
                           range. Perform the following:
                           1. Remove the input signal from the probe, return the offset to
                              zero, and Autobalance the probe. Does the trace return to
                              approximately the center of the graticule? If not, proceed to
                              step 7.
