Important note
All lisa devices connected to the
mains supply have a low power con-
sumption which may lead to the
device feeling warm. This is normal
and does not interfere with the nor-
mal function of the devices.
These signalling systems have a
high operational safety. Should any
faults occur in spite of proper instal-
lation and use, please contact your
dealer.
High and low voltage spikes (e.g.
during a thunderstorm) can occur on
the mains supply. The lisa devices
have an integrated electronic con-
troller which may stop working after
these conditions. If this happens
simply unplug each of the devices
and plug them in again.
As a precaution remove all
devices from their sockets
during a thunderstorm.
The use of halogen lamps of or
other equipment (e.g. Microwave
Ovens) may, in rare cases, interfere
with the lisa signals. In these cases
the use of mains filters or suppres-
sors is advisable. Please ask your
dealer.
Maintenance and care
All lisa devices are maintenance
free. Note: To clean, remove from
their mains sockets and wipe over
with a moistened cloth. Never use
alcohol, thinner or other organic
materials.
lisa devices should not be exposed
to excessive direct sunlight, heat,
thick dust, humidity or mechanical
shock.
Note: This product is not protected
against splash water. Do not place
