INTRODUCTION & COVER LETTER Because the device described in FCCID: QDQ-100 uses an already approved FRS radio core in a new application, more explanation is warranted. The original FRS core that will be used in this device has FCC ID: PHC-1428. The grant was given on 6/12/2001. This new device is a special purpose transceiver that is to be used by firefighters and other rescue services for short-range communications during fires, or any usage requiring a breathing air mask. It uses a side-of-head mounted triangular housing. This housing allows the microphone to be placed on the facemask’s voice diaphragm, and repositions the speaker over the ear. The extra circuitry made/assembled by the manufacturer (Safety Tech Industries) is completely contained in the housing. It will be marketed as the model SAV-100 “TeamTalk”. Simple “push-to-talk”, “on/off” and volume controls are done by three push buttons. The interface between the buttons and the PHC-1428 FRS-radio core is achieved by extra circuitry. The device manufacturer will supply the description of this (see enclosed), and all other circuitry in the exhibits. Because of the availability of 9-volt alkaline batteries to fire personnel, a separate voltage regulator is used to lower the 9-volt level to a 5-volt level to operate the PHC-1428. The transceiver emits a distinctive double beep when battery voltage drops below 7 volts. Once the beeping begins, there are 30 minutes of operation time available. The transceiver complies with the “5%Transmit, 5%Receive, 90% standby” standard for portable transceivers. There is no provision for the recharging of batteries. A 47-ohm resistor at the RF output of the radio board and a printed circuit antenna reduce the output power from the PHC-1428. Because of this new antenna system, effective radiated power and spurious radiated emission measurements are included in the exhibits. The effective power level is reduced from the 300mW level described in the PHC-1428 level. Only short-range communications are needed for this device and the higher power to be reduced for this application. For operational simplicity, only two out of the 14 channels present in the PHC-1428 are used. One assigned channel is for normal usage. The second channel is used for special needs, such as mutual aid from other cities or departments. This “alternate” channel is selected by the simultaneous pushing on both up & down volume buttons for 3 seconds. The unit returns to the regular channel upon either repeating the dual buttons, or a powering down (off) of the unit. The selection of what channel is to be “normal” is up to each customer, however, it is programmed to that channel by Safety Tech Industries. The upper pushbutton is used to increase the speaker volume in eight distinct steps. The lower pushbutton lowers the speaker volume, but does not allow the volume to go totally “off”. The manufacturer affects no RF generating subsystem of the PHC-1428 core. The PHC-1428 core is bought in quantity and no on-board functions are changed. For this reason, the frequency stability due to temperature and battery voltage variations, bandwidth and modulation tests are not repeated. The original unit is used as was designed. Safety Tech Industries merely has employed a different method to control the original pushbuttons on the radio core’s PCB board. Thank you, for your time and effort in this project.

FILE NAME: SAF0201 EUT NAME: "Team Talk" SAV-100 THE EUT IS A REDUCED POWER, FRS-BASED TRANSCEIVER. IT IS POWERED BY A SINGLE 9VDC ALKALINE BATTERY. THE EUT IS A PROTOTYPE, USE SERIAL NUMBER: " PROTO1." CUSTOMER REPRESENTATIVE: CURT SEATON (not present) MEASURED BY STEVE PETIX ON 5/22/02 TO FCC PART 95 USING 3 METER OPEN AREA TEST SITES, (OATS). THE EUT MEASURING ANTENNAS ARE: A SCHWARZBECK MODEL VHA9103 BICONICAL ANTENNA, (s/n: A) IS USED FOR 30 TO 300 MHz. AN AILTECH MODEL 96005, (s/n 1095), LOG PERIODIC ANTENNA IS USED FOR 300 TO 1000 MHz. AN EMCO MODEL 3115 s/n 2498 GUIDED RIDGE HORN ANTENNA IS USED FOR 1 TO 18 GHz. THE SUBSTITUTION ANTENNAS IS: A SCHWARZBECK MODEL UHA-9105 TUNED DIPOLE IS USED FOR 300 TO 1000 MHz. THE ANTENNAS ARE FACING THE YELLOW TRANSMIT BUTTON SIDE FOR ALL MEASUREMENTS. THE EUT IS 1.5 METERS ABOVE THE SHEET STEEL GROUND PLANE. ALL MEASUREMENTS USE PEAK DETECTION. ADVANTEST MODEL R3361A & HP MODEL 8569B SPECTRUM ANALYZERS ARE USED. The EUT is based on a previously approved FRS radio core. Its FCC ID is: PHC-1428. This FRS radio core is used in the Audiovox model FR-1428 Two Way Family Radio. It is manufactured by Linkomm Communications Network of South Korea. Safety Tech Industries, Inc. is using this FRS radio core electronically unchanged. It places the radio core inside a new housing that is to be mounted on the face mask of firefighters. The housing contains circuitry on a mother board that interfaces with the FR-1428's controls. This circuitry allows the use of any of the 14 channels. Safety Tech Industries elected to use channel 12 (467.6625MHz) for a "common" channel on all units. The only RF modification is the use of a PCB antenna with a 47 ohm loading resistor mounted on the interface electronics board. The PCB antenna and load resistor reduce the effective radiated power from the 300 milliwatts claimed by Linkomm Communications for the PHC-148 radio core. In this unit, Channel, 467.714 MHz, is used for all measurements. All measurements are performed with the bottom edge of the TeamTalk housing parallel to the ground. This is similar to its actual orientation on the firefighter's face mask when he/she is looking straight ahead. The TeamTalk FCC ID is: QDQ-100. continued on next page TEST & MEASUREMENT DATA REPORT FOR "TEAM TALK" TRANSCEIVER CARRIER FIELD STRENGTH MEASUREMENTS: The EUT's unmodulated carrier is measured on a spectrum analyzer. The maximum level is measured by scanning the receive antenna height from 1 to 4 meters. No preamplifier is used at the spectrum analyzer input. No amplifier is used at the signal generator output.

The dipole is energized with a Marconi model 2022C signal generator. Due to insufficient power, a 32 dB preamplifier on the spectrum analyzer input was needed to boost the signal from the receive antenna. The output of the signal generator was raised until the resulting 467.714MHz signal level matched the level recorded from the field strength measurement above.
