4. For large consoles (width greater than about 1.5’ or 45 cm), the FIT1/e should be located in the
middle third of the console, not to the right or left sides. This requirement helps to ensure that
the FIT1/e pairs with the user on the equipment and not a neighbor or passer-by. Please see
Figure 2 for details. For the FIT1e to achieve optimal EM range, place the FIT1e as close to the
user as possible within the console.
5. When determining mechanical fastening methods minimize material on or around printed
antenna (on both sides of PCB) and the EM coil (on FIT1e). Placing material in these areas will
affect the radiation pattern, potentially degrading performance. See “Printed Antenna Keepout”
in Figure 3. If possible, the module should be placed on or close to the front plastics of the
console or enclosure.
6. It is important that the FIT1/e is not placed behind the LCD or PCBs of other electronics within
the console/ enclosure. The RF and EM (on the FIT1e) circuit provide much greater reliability if
line of sight is available between the module and the user, with only the console/ enclosure
plastics in between. In some applications space does not allow for the module to adhere to this
guideline. In these cases the module can partially sit behind PCB material provided that it is free
of ferrous or nickel metals. This case should be avoided if possible.
For the FIT1e, it is important that the module is positioned away from sources of electric noise such as
fans, motors, generators etc. Devices causing large amounts of electrical noise, degrading EM signal.
LCD screens may also cause noise to the EM circuit. If possible position the FIT1e away from LCD
screens. If this is not possible, maximize the distance from the LCD screen to the module.
