welding equipment or other devices generating strong (electro)
magnetic fields. Exposure to strong (electro) magnetic fields
may cause malfunction and corrupt the communication.
• Moving the equipment rapidly between warm and cold
temperatures may cause condensation (water droplets) to form
on its internal and external surfaces. Water droplets may cause
malfunction of the equipment and corrupt or end
communication or damage the equipment. When condensation
is noticed, stop using the equipment. Switch off the phone,
remove the battery and unplug the mains adapter from the
power outlet. Wait until the moisture evaporates from the
