CFXPT-2LPRS TRQNSMITTER

Owner’s Manual 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. FCC COMPLIANCE NOTICE The PT-2 transmitter (FCC ID CFXPT-2) is authorized by rule under the Low Power Radio Service (47 C.F.R. Part 95) and must not cause harmful interference to TV reception or United States Navy SPASUR installations. You do not need an FCC license to operate this transmitter. This transmitter may only be used to provide: auditory assistance to persons with disabilities, persons who require language translation, or persons in educational settings; health care services to the ill; law enforcement tracking services under agreement with a law enforcement agency; or automated maritime telecommunications system (AMTS) network control communications. Two-way voice communications and all other types of uses not mentioned above are expressly prohibited. CAUTION: Any changes or modifications to this device could void the user's authority to operate the equipment. CHANNEL USE POLICY The channels authorized to LPRS systems by the FCC rules are available on a shared basis only and will not be assigned for the exclusive use of any entity. Those using LPRS transmitters must cooperate in the selection and use of channels in order to reduce interference and make the most effective use of the authorized facilities. Channels must be selected in an effort to avoid interference to other LPRS transmissions. WARRANTY The PT-2 is warranted to be free of defects in materials and workmanship for a period of one (1) year from the date of purchase. Just return the unit to the factory and we will repair or replace it at no charge.

Two-way voice communications and all other types of uses not mentioned above are expressly prohibited. CAUTION: Any changes or modifications to this device could void the user's authority to operate the equipment. The LPRS device is too small for a compliance statement. The compliance statement is placed in a prominent location in the instruction manual supplied to the user.

PART 95 ATTESTATION June 3, 2005 Federal Communications Commission Authorization & Evaluation Division 7345 Oakland Mills Road Columbia, Maryland 21046 Gentlemen: Reference: CFXPT-2 This equipment meets the Low Power Radio Service requirements of the FCC Rules, Part 95. Programming of this product’s transmitter power and its transmit frequencies can be performed ONLY by the manufacturer. The operator cannot increase transmitter power or program transmit frequencies using the equipment’s external operation controls. (Rule 95.649) Sincerely. Communications Specialists, Inc.

PT-2 DESCRIPTION OF CIRCUITRY The PT-2 transmitter is a PLL synthesized design using a 1.0ppm TCXO as the reference oscillator. A microprocessor controls all of the functions of the PLL, oscillator, and amplifier stages. The circuit has a 1 stage VCO oscillator locked to the PLL, followed by 4 stages of amplification. Any harmonic or spurious signals are filtered out by a 5th order 230Mhz low pass filter before reaching the antenna.

PT-2 FACTORY TUNE UP PROCEDURE PRIOR TO POTTING 1. Download test firmware. This changes the PT-2 frequency to 216.000Mhz. 2. Adjust trimmer pot VR-01 to set the VCO frequency to 216.000Mhz (+ or - 20Hz). 3. With the frequency at 216.000Mhz, align VC-1 so the VCO test voltage is .3v (+ or - .1V). 4. Check power output to make sure it is 17.0dBm to 19.5dBm. 5. Check that all harmonics or spurious signals are at least 50dB down from main carrier. 6. Download test firmware to change the transmitting frequency to 222.000Mhz 7. Check that the VCO frequency is 222.000Mhz (+ or - 20Hz). 8. Check that the VCO test point is less than 1.7v. 9. Check that the power output is 17.0dBm to 19.5dBm. 10. Check that all harmonics or spurious signals are at least 50dB down from main carrier.

Equipment marketed to a consumer must be capable of complying with the necessary regulations in the configuration in which the equipment is marketed. Where special accessories, such as shielded cables and/or special connectors are required to enable an unintentional or intentional radiator to comply with the emission limits in this part, the equipment must be marketed with, i.e. shipped and sold with, those special accessories. However, in lieu of shipping or packaging the special accessories with the unintentional or intentional radiator, the responsible party may employ other methods of ensuring that the special accessories are provided to the consumer, without additional charge. Information detailing any alternative method used to supply the special accessories for a grant of equipment authorization or retained in the verification records, as appropriate. The party responsible for the equipment, as detailed in § 2.909 of this chapter, shall ensure that these special accessories are provided with the equipment. The instruction manual for such devices shall include appropriate instructions on the first page of text concerned with the installation of the device that these special accessories must be used with the device.
