4. Improper use
Improper use can lead to personal injury or property damage.
Never use controllers with DuoFern radio technology for the remote control of de-
vices and systems with increased safety-relevant requirements or where there is an
increased accident risk. Applications of this kind require additional safety equipment.
Observe the respective statutory regulations for the installation of such systems.
ATTENTION!
- Incorrect or leaking batteries can cause damage to the DuoFern
transmitter.
• Never use two different battery types.
• Never use new and old batteries together.
• Take the batteries out of the remote control if it is not used for a longer period of
time.
• If a battery leaks, carefully wipe off the fluid in the battery compartment and insert
new batteries.
For devices containing one or more button/coin-cell batteries,
the following safety instructions must be observed:
If the coin-cell battery is swallowed, it can cause severe internal burns and
death within just 2 hours.
• Children must not replace batteries.
• Do not swallow the battery, risk of acid burns.
• Store the new and used batteries out of the reach of children. If the battery compart-
ment does not close securely, stop using the product and keep it away from children.
If you believe that batteries may have been swallowed or made their way into any
part of the body, seek medical advice immediately.
Risk of fire and explosion
• There is a risk of fire or explosion if the battery is replaced with an incorrect type.
In addition, replacing a battery with an incorrect type can override a safety device.
• Throwing a battery into a fire or hot oven or mechanically crushing or cutting a bat-
tery can lead to an explosion.
• If the battery is placed in an environment with extremely high temperatures, this can
lead to an explosion or a spill of flammable liquid or flammable gas.
• A battery exposed to extremely low air pressure can cause an explosion or the re-
lease of flammable liquids or gases.
