3 Installation and starting
3.1 Location of the terminal and the base
The ideal place for the base is in the centre of the zone to be covered with a large open area
around. The inside antenna is on the left side.
It's mandatory to avoid docking the terminal on a metal surface and to place the hand under
the printer during a communication, the range is strongly reduced.
Also, a great vertical metal plane close the base (doors of refrigerator, large home
appliances, vending machines) can reduce the range distance.
If there are several Bluetooth technology bases it is necessary to position them at least 2
metres from each other.
Last point, equipment such as Home cordless telephones, cellular phones, can emit
harmonics which could disturb the terminal at 2,45 Ghz.
Some Microwave ovens disturb the 2,45 Ghz ISM Band. Don’t place the base or the
terminal at less than 3 m of any microwave oven in use.
Place the terminal on its base on a clear, flat surface near an electric socket and a telephone
socket.
The terminal should be placed far from any very hot zones, protected from vibrations, dust,
damp and electromagnetic radiation (computer screen, micro-wave oven, anti-theft barrier
etc.).
Bluetooth technology Regulations:
Please check your country regulation about the 2,45Ghz ISM band.
The I7780 system uses 20dBm (100mW) Bluetooth technology which requires no license
and which is free of declaration in almost the whole EEC.
