Chapter 10: Maintenance
NOTE:
The paper rolls have a pink indicator strip near the end of the
roll. When you see the pink strip, you have only a few feet of paper
remaining on the roll. Replace the expended roll as soon as you can.
Reconditioning the Battery
Over time, the battery charge level indicator will cease to accurately indicate the
actual battery charge. In the worst case, the variance between the indicated charge
level and the actual charge will be less than 10%.
To maintain the accuracy of the charge indicator, a full charge and drain cycle
should be performed, with no intermediate cycles. This cycle, from full to empty, is
known as reconditioning.
If it is important to maintain the maximum correlation between the battery charge
indicator and the actual battery charge, you can also purchase and use the optional
external battery charger (BC II). See Appendix K, "Accessories and Supplies".
When the BC II senses the need, it will automatically recondition the battery. When
reinstalled, the reconditioned battery will communicate the correct charge level to
the battery charge indicator.
Battery Disposal
At end-of-life, batteries should be recycled or discarded safely. Discarding batteries
in unsorted waste is improper disposal, and may be harmful to the environment and
human health. Your local waste authority will have information on return and
collection systems in your area.
For California consumers, contact Particle Measuring Systems, Customer Service
Department at (877)-475-3317 for instructions on returning used, rechargeable
batteries for reuse, recycling, or proper disposal at no cost.
