• Spread Spectrum – either a 915 MHz or 2.4 GHz
modem.

modem (Europe and Japan: 900/1800 MHz; USA
and Canada: 900/1900 MHz).

The Base station operator is responsible for complying
with local regulations for radio operation. In the US, the
FCC regulates the use of radio transmitters, requiring a

if you need advice on obtaining the proper license in the
USA.
The internal PDL radio modem comes with a number of
preset frequencies programmed at TPS.
WARNING
The use of these preset frequencies without
a license is illegal. Contact your local
