• Avoid deep discharging the batteries as this can cause
the cell polarity to reverse and make the battery
useless.
Protect the environment
Please dispose of any unwanted dry batteries and
rechargeable batteries carefully. They should also be
removed from the instrument if it is to be scrapped. If
facilities in your country exist for collecting such waste or
for recycling, please make use of these rather than
throwing the batteries in the normal trash. You will often
be able to return used batteries to the place where you
purchase new ones.
