Detailed installation
6.1. Selection of place for PBX
Aspects which must be taken into consideration when selecting a place for the PBX:

Good visibility and accessibility (the exact time and other data about operation is
shown in the display of the PBX in operation).

Protection from damp and extreme temperatures: the PBX must definitely
not be located near heat sources (above heaters) or in a place where direct
sunlight may fall. Also avoid damp places (bathroom, cellar), places where
the temperature changes rapidly (near doors, windows, air-conditioning),
dusty places (workshops etc) or places with aggressive gases (battery
rooms, boiler rooms) and places with high vibrations and shocks
(compressors, heavy industrial operations). The PBX has an upright
operating position.

Installing circuits in building: by choosing a suitable location for the PBX (centre
of building or administrative centre) it is possible to reduce the costs for the
building of the circuits. If there are already circuits in the building, the location of
the PBX is generally already determined thereby and it cannot be changed.

Possibility of direct connection using modules with connectors RJ-45.

Quality of GSM signal: if one part of your configuration is (or later will be) a GSM
module, it is necessary to take into account the fact that the cable from the PBX
to the GSM cable is usually about 3 metres long (maximum 10m). It is therefore
necessary to make sure that in the specified circuit around the selected place for
the PBX there is a place with a good level of GSM signal suitable for locating the
GSM antenna. *)

Ensuring against theft: when selecting a position, it is recommended that the
conditions of the insurance company be respected.

Opening cover: there should be at least 10 cm of free space right and left of the PBX.
Note: In places with a poor level of GSM signal it is possible to use an independent
(external) GSM gateway which can be installed at a distance of up to 500 m from the PBX (!)
in a place with a good GSM signal (on high building, hill etc.) and ensure both cheap access
to the GSM network and reliable function in places where there is very poor coverage
(borderline areas).
6.2. Unpacking and checking
If you haven’t yet done so, check that the delivery is complete. The packaging of
the basic module is usually used for the transport of other independently purchased
items of the PBX (modules etc.). You can usually check them using the delivery note
and order numbers which are on all parts. The remaining components in the upper
part of the box are the accessories of the basic module. Remove the separate basic
