Regulatory Information/disclaimers
Installation and use of this Wireless Radio device must be in strict accordance with the
instructions included in the user documentation provided with the product. Any changes or
modifications made to this device that are not expressly approved by the manufacturer may
void the user’s authority to operate the equipment. The Manufacturer is not responsible for
any radio or television interference caused by unauthorized modification of this device, of the
substitution or attachment. Manufacturer and its authorized resellers or distributors will

The FCC Wants You to Know
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
a) Reorient or relocate the receiving antenna.
b) Increase the separation between the equipment and receiver.
c) Connect the equipment to an outlet on a circuit different from that to
which the receiver is connected.
d) Consult the dealer or an experienced radio/TV technician.
FCC Warning
Modifications not expressly approved by the manufacturer could
void the user authority to operate the equipment under FCC
Rules.

Product description
SA tag:
The SAT is used to track assets in real time. It is based on an RF transceiver and a
microcontroller.
It uses the iLocate proprietary protocol which provides a 2 way, half duplex communication with
the base station.
The unit is powered by a 2/3 AA lithium thionyl chloride (Li-SOCl2) battery and is hermetically
sealed with no connectors available to the end user.

System test configuration
SAT
The unit tested was configured with all hardware options present (Motion sensor M1 and keypad
connectors J2 and J3).
Since the unit, under its normal operation, does not transmit data periodically, for emissions
measurements, the SAT was programmed with a special test software to transmit packets
continuously at maximum output power, maximum duty cycle (20%) with power amplifier enabled.
Normal duty cycle, assuming worst case, one event per second is 0.5% (5msec transmit time per
1 second).
Theory of operation
The SAT method of communication is synchronized event based reporting, the SAT spends most
of its time in low power sleep mode. When an event happens, the SAT sends a report to the base
station. In order to avoid packet collisions and associated detection methods, the system uses a
synchronous protocol, that is, An SAT can transmit data only after receiving a synchronization
signal from the base station.

Unit definitions:
Base station, referred to as PBS: A radio device that transmits data to and from the tag (SAT) to a
personal computer (PC), also provides synchronization signal. The unit is powered by a DC power
supply.
Beacon, referred to as PBC: A radio device that defines a location. Location detection can be
realized through one or more PBCs. The unit is powered by a DC power supply.
Tag (SAT): A radio device that is used to track and monitor assets. It communicates with the PBS
and can detect the PBC signals.
