NV9USB M
AINTENANCE
G
UIDE
The NV9USB Validator has been designed to minimise any
performance variation over time. Much of this is achieved by
careful hardware and software design. However, depending upon
the environment the NV9USB may at some time require cleaning,
belt changing or note path clearing.
Cleaning – Every Month (Or As Required)
CAUTION: DO NOT USE SOLVENT BASED CLEANERS SUCH AS ALCOHOL,
PETROL, METHYLATED SPIRITS, WHITE SPIRIT OR PCB CLEANER. THIS WILL
RESULT IN PERMANENT DAMAGE TO THE VALIDATOR, ONLY USE A MILD
DETERGENT.
To clean, slide the red release catch on the end of the NV9USB Validator to the left, to open
the note path. The note path and lozenge are now exposed for cleaning.
Carefully wipe the surfaces with a soft lint free cloth that has been dampened with a water
and mild detergent solution (i.e. household washing up liquid). Take particular care around
all the sensor lenses (see below), ensuring they are clean and dry.
CAUTION: WHEN CLEANING THE
RECESSED FRONT SENSORS,
USE A SMALL SOFT BRUSH OR
COTTON WOOL BUD
If a lens has become badly scratched
do not attempt to polish it. Contact
ITL for further advise, as there may
be damage to the optical properties
of the lens.
