CLEANING
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.
CALIBRATION INTERVAL
The recommended calibration interval is one year. Adjustment
should only be performed by qualified personnel. (A Performance
Verification procedure is included in this manual.)
SERVICE STRATEGY
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.
TROUBLESHOOTING
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.
