Handling the Batteries
• Improper or incorrect use of batteries may cause corrosion or
battery leakage, which could cause personal injury or damage
to property.
• Install the batteries correctly by following the polarity (+ and –)
indications in the battery compartment.
• Use only the types of the batteries which are indicated in this
manual.
• Do not install new batteries with used ones and do not mix
different types of batteries.
• Do not dispose of the used batteries as domestic waste.
Dispose of them in accordance with local regulations.
• If you are not going to use the unit for a long time, remove the
batteries to avoid damage from battery leakage and corrosion.
Due to the short battery life span of some alkaline batteries, it
is recommended to use rechargeable batteries. You will need to
purchase a charger to charge the rechargeable batteries. This
saves money and is more environmentally friendly.
