7 ROUTINE MAINTENANCE
7.1 Introduction
The NV9 range of products have 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 validator and/or its modules
may at some time require cleaning, belt changing or note path clearing.
7.2 Recommended Cleaning Intervals
Innovative Technology Ltd recommends to clean the optical lenses every month or
as required. Dirt, dust or other residue leads to bad note acceptance and other
performance degradation.
Please refer to Second Level Support: Section 9.6 for comprehensive cleaning
instructions.
7.3 Recommended Belt Changing Intervals
Innovative Technology Ltd recommends that you change the drive belts of the
NV9USB+ every 6-12 months or as required, dependant on environmental factors.
If dirt can be seen to be building up or if the belts themselves have had excessive
use and are starting to wear, then this time period may not apply and they would
need to be swapped sooner.
Please refer to Second Level Support: Section 9.7 for comprehensive belt changing
instructions.
