Selecting an installation location / Checking the reception quality of the mobile phone
network
Before installing the SmartBox
®
, you must check whether the reception quality of the
applicable telecommunications network is sufficient. The easiest way to do this is to have a
mobile phone ready at the designated place of installation. As a precondition, the mobile
phone must be registered with the same telecommunications network (in Germany e. g. T-
Mobile, Vodafone, O
2
) as the SIM card which is used for the SmartBox
®
.
If there is no suitable mobile phone at hand, you can also perform the test with the SIM card
for the SmartBox
®
. In this case, insert this activated SIM card into a mobile phone and switch
it on again.
The reception quality at the designated place of installation can simply be seen from the
indication in the mobile phone screen. At least one bar/scale line of the reception quality
indicator must be visible on the screen. If the reception quality is very bad (no bar/scale line
visible), another installation site should be picked and tested (possibly in another room).
If the reception quality is very bad, an additional antenna (accessory) should be used. It can
be installed e. g. in front of a basement window.
