PT-2 LAW ENFORCEMENT TRACKING
TRANSMITTER
INTRODUCTION
The Communications Specialists Model PT-2 transmitter is used as a homing device to
locate persons or stolen goods under authority or agreement with a law enforcement
agency (federal, state, or local) having jurisdiction in the area where it is placed. It is
programmed at the factory to transmit on any one of 200 individual narrowband channels
in the Low Power Radio Service (LPRS). This allows 200 transmitters to be used
simultaneously in an area for unprecedented flexibility. Power output is 80 mW. It uses
a widely available CR123A Lithium battery which transmits continuously for 12 days or
a rechargeable battery which transmits continuously for 6 days. The battery snaps into a
holder which is attached to the PT-2. A retainer snaps over the battery to hold it in under
even the most demanding conditions. It is small in size (1.7"x1.2"x.9" without magnet)
with an 8" attached loaded antenna. Its total weight is 1.5 oz. It includes a steel keeper
on one side that allows the supplied rare earth magnet to keep it attached to the bottom of
a vehicle or other item for quick and easy installation. For non magnetic use, the magnet
need not be used. The PT-2 utilizes a TCXO rather than a fragile crystal so it is almost
indestructible.
BATTERY INSTALLATION
Snap a CR123A battery into the battery holder. Be sure to observe the proper polarity
by noting the diagram on the inside of the holder. If the battery is accidentally reversed,
the PT-2 will not operate but it will not be damaged. Just pop out the battery and reverse
it to resume operation. Snap the retainer over the battery to hold it in. Be sure to test the
PT-2 on your receiver before use to ascertain that it is operating. To remove the battery,
pry up the bottom edge of the retainer with a small screwdriver to pop it off.
