Description of the LAUR
The LAUR operates within the
frequency band from 215 MHz
to 250 MHz. Within that band, it
uses a 200-kHz or 800-kHz
bandwidth channel,
depending on the selected data
rate. The user is responsible for
inquiring about local radio
frequency regulations and using
the frequency band accordingly.

depending on the selected data
rate. The user is responsible for
inquiring about local radio
frequency regulations and using

The LAUR unit operates from a
10.5 VDC to 15.0 VDC power
supply voltage. The power
supply should be capable of
generating a minimum current
of 15 A. A 12 VDC battery can
be used as a power supply. The
power supply used shall be
compliant with the rules and
regulations of the FCC, of
Canada or with other local
regulations.
