General warnings
•
Fasten the access point/repeater in the desired position, considering
that as the device being installed is a radio device, the following simple
rules must be observed:
–
avoid enclosing the appliance between two metal walls;
–
the effi ciency of radio transmission is reduced when there are
obstacles, metal shelving or other objects that may block the
reception of the wireless signals;
–
if the product is wall-mounted, fasten it to a masonry wall rather
than a metal wall, to improve the range of the signal;
–
remember that the best position for the access point is one where it
is "visible" to the other devices. It should be positioned in such a way
as to minimise any obstacles;
–
like all radio equipment, avoid installing the access point near other
electronic appliances, so as to avoid interference.
•
do not install the instruments in environments with the following
characteristics:
–
strong vibrations or knocks;
–
exposure to water sprays;
–
exposure to direct sunlight or the elements in general;
–
If the appliance is used in a way that is not described by the
manufacturer, the specifi ed level of protection may be aff ected.
2.2 Terminal and Sensor
The terminal and the sensor can be fastened to the wall using the support
shown in the fi gure (included with the product).
Part A shown in the fi gure is used to lock the instrument to the support.
A screwdriver will be required to remove the instrument. This plastic part
may be essential for hotel-type applications. For applications where the
instrument needs to be removed frequently (residential, offi ce,...) part A
can be eliminated simply.
