used with care. If you adhere to
the
instructions below, your pearly

order to avoid damage to the device. Do not
place the device onto/into a heat source (not
even to dry), such as a microwave, an oven,

– Do not store your computer in a hot environ-
ment (e.g. on a hot dashboard in summer).
High temperatures can damage the batteries

solutions or aggressive cleaning products.
Life span
– The devices have a shelf-life of max. 7 years.

– Strong electro-magnetic fields (e.g. from cell
phones, CB radio, or microwaves) can make
the device function improperly. The safety
distance should be 30 cm.
– The computer may only be connected to the
devices listed above. These should comply
with the IEC60950-1 standard in order to avoid
any damage to the device or other hazards
(such as electrocution hazards).
