The exterior of the amplifier should be cleaned using a soft cloth
only moistened with water or isopropyl alcohol. The use of
abrasive agent, strong detergents or other solvents may damage
the exterior of the amplifier.
The recommended calibration interval is one year. Adjustment
should only be performed by qualified personnel. (A Performance
Verification procedure is included in this manual.)
Defective amplifiers must be returned to a LeCroy service facility
for diagnosis and exchange. A defective amplifier under warranty
will be replaced with a factory refurbished one. An amplifier that is
not under warranty can be exchanged for a factory refurbished
unit. A modest fee is charged for this service. A defective
amplifier must be returned in order to receive credit for the
amplifier core.
Calibration adjustments require the use of specialized signal
sources which are not commercially available. Amplifiers which
do not pass the performance verification must be returned to the
factory for service.
If the amplifier is not operating properly the problem may be the
way in which it is used. Before assuming the amplifier is
defective, perform the Functional Test as described in the
Performance Verification procedure.
The procedure for returning a product for calibration or service is

to return the product. All returned products should be identified by
model number and serial number. Provide your name and contact
number and if possible describe the defect or failure. In case of
