WARNING
Risk of explosion and release of harmful substances
Improper handling of lithium batteries can result in an explosion of the batteries.
Explosion of the batteries and the released pollutants can cause severe physical injury. Worn
batteries jeopardize the function of the device.
Note the following when handling lithium batteries:
•
Replace spent batteries promptly. You can find information on installing and removing
the backup battery in the Operating Instructions.
•
Replace the lithium battery only with an identical battery or types recommended by the
manufacturer.
•
Do not throw lithium batteries into fire, do not solder on the cell body, do not recharge,
do not open, do not short-circuit, do not reverse polarity, do not heat above 100°C and
protect from direct sunlight, moisture and condensation.
Strong high-frequency radiation
NOTICE
Observe immunity to RF radiation
The device has an increased immunity to RF radiation according to the specifications on
electromagnetic compatibility in the technical specifications.
Radiation exposure in excess of the specified immunity limits can impair device functions,
result in malfunctions and therefore injuries or damages.
Read the information on immunity to RF radiation in the technical specifications.
ESD Guideline
Electrostatic sensitive devices can be labeled with an appropriate symbol.
NOTICE
Electrostatic sensitive devices (ESD)
When you touch electrostatic sensitive components, you can destroy them through voltages
that are far below the human perception threshold.
If you work with components that can be destroyed by electrostatic discharge, observe the
ESD Guideline (Page 111).
