KLLTP-323Family Radio Transceiver

1 OWNER’S MANUAL FRS RADIO WRF 108 INTRODUCTION Your FRS radio is a portable, easy-to-use, two-way radio with clock and NOAA receiver that you can carry almost anywhere. It makes you can contact others as well as watching NOAA WX broadcasts in one unit meanwhile grasping time. Use it at shopping malls, amusement parks, sports events, or at the beach to contact family and friends, or for vital communications in a neighborhood watch. Your radio has 14 channels and 38 different quiet codes. If someone else is using the channel you selected and you do not want to hear that person, select another channel or use the quiet feature. You can talk with a person who has a FRS radio if both radios are tuned to the same channel and quiet code. Your radio has auto-squelch (FRS only), which means you will not hear anything on a channel unless someone is transmitting nearby on the same channel. You can turn off auto-squelch to hear weaker, distant transmissions. Also, if the radio is idle for a period of time of 2 hours, it automatically shuts off. It turns on again when you press POWER/VOL key for 2 seconds. You can connect an optional earphone/microphone and a charger (not supplied) to the radio. And, the belt clip lets you take your radio almost anywhere. FCC INFORMATION Important: Do not open your radio to make any internal adjustments. Your radio is set up to transmit a regulated signal on one of 14 assigned frequencies. It is against the law to alter or adjust the settings inside the radio to exceed those limitations. Any adjustments to your radio must be made by a qualified technician using the proper test equipment. To be safe and sure: ! Never open your radio’s case. ! Never change or replace anything in your radio except the batteries. Your radio might cause TV or radio interference even when it is operating properly. To determine whether your radio is causing the interference, turn it off. If the interference goes away, your radio is causing it. Try to eliminate the interference by: 2 ! moving your radio away from the receiver ! calling your local service store for help If you cannot eliminate the interference, the FCC requires that you stop using the radio. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. SAFETY INFORMATION Your wireless hand-held portable transceiver contains a low power transmitter. W hen the Push-to-Talk button is pushed it sends out radio frequency (RF) signals. The device is authorized to operate at a duty factor not to exceed 50%. In August 1996, the Federal Communications Commission (FCC) adopted RF exposure guidelines with safety levels for hand-held wireless devices. CAUTION: To maintain compliance with the FCC’s RF exposure guidelines, hold the transmitter and antenna at least 2 inch (5 centimeters) from your face and speak in normal voice, with the antenna pointed up and away from the face. If you wear the handset on your body while using the headset accessory, use only the supplied belt clip for this product and when transmitting, take it out of the belt to ensure that the antenna is at least 1 inch (2.5 centimeters) from you body. Use only the supplied antenna. Unauthorized antennas, modifications, or attachments could damage the transmitter and may violate FCC regulations. 3 USING THE RADIO A.

To start using your radio, insert four AAA batteries into the battery compartment, noting the polarities. As soon as you connect the power, the unit will enter the clock mode and the cleared time will display on LCD. Note: Once your batteries are used up, you should replace all the four alkaline batteries with new ones. Then the cl…

ALIGNMENT PROCEDURES Important: The FCC requires that any frequency adjustme nt on a radiophone must be do ne by authorized person, who is the holder of a current first or second class radiotelephone license. This unit has been fully aligned at the factory before shipment and does not normally require furt her adjust ment. W hen necessary, however, the unit may be aligned as indicated below. Do not adjust any circuit in this radiotelephone unless you understand the circuit operation and have experience of adjusting radiotelephone. Tampering with the radiotelephone may upset the alignment and lower its performance. Test Equipment Required: Regulated DC power supply, 0~12V, 1A or higher; or 8.4V, 1A Audio signal generator, 10Hz~2KHz Digital multi meter Deviation meter Frequency counter, 0~500MHz high impedance Oscilloscope RF power meter, 5W High frequency standard generator,>160MHz Tracking generator, >160MHz Distortion analyzer Audio level meter T-coupler Aligning drivers, etc.

ENGINEERING STATEMENT For Type Certification of Tekcom Industries Limited Model No: TP-323 FCC ID: KLLTP-323 I am an Electronics Engineer, a principal in the firm of Hyak Laboratories, Inc., Springfield, Virginia. My education and experience are a matter of record with the Federal Communications Commission. Hyak Laboratories, Inc. has been authorized by Tekcom Industries, Ltd., to make type certification measurements on the TP-323 transceiver. These tests made by me or under my supervision in our Springfield laboratory. Test data and documentation required by the FCC for Type Certification are included in this report.

Photographs of the equipment are submitted as a separate exhibit. 3. Quantity production is planned. 4. Technical description: a. 11k0F3E emission b. Frequency range: 462.5625 - 467.7125 MHz. c. Operating power of transmitter is fixed at the factory at less than 0.5 W ERP(d). d. Maximum power permitted is 0.5 watts, and the TP-323 fully complied with that power limitation. e. The dc voltage and dc currents at final amplifier: Collector voltage: 5.9 Vdc Collector current: 0.29 A f. Function of each active semiconductor device: See Appendix 1. g. Complete schematic diagram is submitted as a separate exhibit. h. A draft instruction manual is submitted as a separate exhibit. i.

A description of circuits and devices employed for suppression of spurious radiation and for limiting modulation is included in Appendix 3. l. Not applicable. 5. Data for 2.985 through 2.997 follow this section. C. RF Power Output (Paragraph 2.985(a) of the Rules) The TP-323 has a permanently attached built-in antenna without provisions for a coaxial connector. Therefore RF power output was measured by substitution. The transmitter was tuned by the factory. TABLE 1 Operating Freq., MHz Power watts into a dipole antenna 462.5625 0.49 D. MODULATION CHARACTERISTICS 1. A curve showing frequency response of the transmitter is shown in Figure 1. Reference level was audio signal output from a Boonton 8220 modulation meter with one kHz deviation. Audio output was measured with an Audio Precision System One integrated test system. 2. Modulation limiting curves are shown in Figure 2, using a Boonton 8220 modulation meter. Signal level was established with a Audio Precision System One integrated test system. The curves show compliance with paragraphs 2.987(b). 3. Figure 3 is a graph of the post-limiter low pass filter which provides a roll-off of 60Logf/3 dB where f is audio frequency in kHz. Measurements were made following EIA RS-152B with an Audio Precision System One integrated test system on the Boonton 8220 modulation meter audio output. 3 4. Occupied Bandwidth (Paragraphs 2.989(c) of the Rules) Figure 4 is a plot of the sideband envelope of the transmitter output taken with a Tektronix 494P spectrum analyzer. Modulation corresponded to conditions of 2.989(c)(1) and consisted of 2500 Hz tone at an input level 16 dB greater than that necessary to produce 50% modulation at 2895 Hz, the frequency of maximum response.

The horizontal scale frequency) is 10 kHz per division and the vertical scale amplitude) is a logarithmic presentation equal to 10 dB per division. E. SPURIOUS EMISSIONS AT THE ANTENNA TERMINALS (Paragraph 2.991 of the Rules) The TP-323 has a permanently attached antenna. There is no connector for an external antenna. Therefore, no antenna terminal conducted measurements were made. F. DESCRIPTION OF RADIATED SPURIOUS MEASUREMENT FACILITIES A description of the Hyak Laboratories’ radiation test facility is a matter of record with the FCC. The facility was accepted for radiation measurements from 25 to 1000 MHz on October 1, 1976 and is currently listed as an accepted site. G.
