Headline I & C, Inc. Misung Bldg, Guro-Dong 612-6, Guro-Gu, Seoul, Korea (152-865) www.headline.co.kr www.headline.co.kr LANDMOBILERADIO HL-1000 SERIES LANDMOBILERADIO HL-1000 SERIES SAFETY TRAINING INFORMATION Your FM radio generates RF electromagnetic energy during transmit mode. This radio is designed for and clas- sified as "Occupational Use Only", meaning it must be used only during the course of employment by individuals aware of the hazards, and the ways to minimize such hazards. This radio is NOT intended for use by the "General Population" in an uncontrolled environment. This radio has been tested and complies with the FCC RF exposure limits for "Occupational Use Only". In addition, your FM radio complies with the following Standards and Guidelines with regard to RF energy and electromagnetic energy levels and evaluation of such levels for exposure to humans: FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3kHz to 300GHz. American National Standards Institute (c95.3-1992), IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields-RF and Microwave. The following accessories are authorized for use with this product. Use of accessories other than those specified may result in RF exposure levels exceeding the FCC requirements for wireless RF exposure.; Li-Ion Battery Pack (BP-227), Belt Clip (BC-98), and External Speaker-micro phone (HM-138). To ensure that your expose to RF electromagnet- ic energy is within the FCC allowable limits for occupational use, always adhere to the following guidelines: DO NOT operate the radio without a proper antenna attached, as this may damaged the radio and may also cause you to exceed FCC RF exposure limits. A proper antenna is the antenna supplied with this radio by the manufacturer or antenna specifically authorized by the manufacturer for use with this radio. DO NOT transmit for more than 50% of total radio use time ("50% duty cycle"). Transmitting more than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. The radio is transmitting when the "TX indicator" lights red. You can cause the radio to transmit by pressing the "PTT" switch. ALWAYS keep the antenna at least 2.5cm (1inch) away from the body when transmitting and only use the FM radio belt-clip which is listed on page vi when attaching the radio to your belt, etc., to ensure FCC RF exposure compliance requirements are not exceeded. To provide the recipients of your transmission the best sound quality, hold the antenna at least 5cm (2inch) from your mouth, and slightly off to one side. LANDMOBILERADIO HL-1000 SERIES 1.

THEORY OF OPERATION ON HL SERIES The HL Series Handheld Radio Transceivers are comprised of one main PCB. The main PCB contains the transmitter, receiver, and control circuits. Receiver The receiver circuit adopts dual conversion super heterodyne with 1 st IF 43.655 and 2 nd IF 455. Front-end Front-end consists of per-selector filter, RF Amplifier, Post-selector filter. The receive signal is routed through C111 and selected by D105~D108, D110~D113 and L106, L107, L110, L111 to amplified around 13dB at RF amp Q101. Front-end adjusts bandwidth by varicap diode tuning. This circuit removes unnecessarily spurious 1 st image. First Mixer The signal from front-end is input to Q103 gate1 of 1 st mixer. Local signal generated from VCO is input to Q103, gate2. These two signals are mixed at Mixer into 1 st IF signal 43.655, which is resonated in parallel at C155, L120, R131 and inputted to XF1, pair crystal filter. IF Amplifier 1 st IF signal from XF1 is amplified about 20dB at IF amp Q105 and imputed to U1, IF DEMOD IC. 2 nd Local oscillator is 43.2. The signal from 2 nd Mixer is refined removing unnecessary spurious signal and detected through high gain linear amp. This detected signal is inputted to U1 pin. AF Amplifier 300 high pass filter U606 removes the signal under 300 of the demodulated signal U1 so that noise under sub tone use is removed. De-emphasis functions to get 6dB/Oct by R641, C638 and this signal controls volume of sound by SW701. IC603 can operate a speaker as audio current amplifier amplifying the signal. The operating current can be reduced by mute signal. Squelch The demodulated signal from U1 is coupled of noise to C173. The noise is filtered and amplified by C176, 177, R147 and used internal amplifier of U1. This noise signal is used as the signal to mute CPU[IC801] D/A . Audio Amp After Sub-tone signal is removed at 300 High pass filter and de-emphasized to 6dB/Oct at R641, C638 the volume of sound is controlled by SW701. IC603 is doing low frequency current amplify as audio amplifier to operate a speaker. IC603 ha mute function and if pin4, mute port is Low, it’s on mute. If it is High, it’s unmated. Transmitter The transmitter consists of buffer, power amplifier, low-pass filter, antenna switch, auto-power control. 2-1) Buffer +2dBm TX RF signal from VCO is amplified to around +15dBm by buffer Q205, Q202 to have desired output power at final amp. Pie style resister attenuator is used between VCO and buffer amp. To minimize the effect of load caused by transmit amplifier in TX. 2-2) Power Amplifier TX RF signal form buffer Amp. Gains 6 Watt output by final Amp Q201. Collect impedance of Q201 states in low so that it is matching to 50ohm by C203, 205, 206, L202, 203and imputed to 5 th low pass filter[L101~103, C101~106]. 2-3) Low Pass Filter 5 th Low pass filter reduces the unwanted spurious for TX output power from final amp. L101~103, C101~106 are chebisheve filter. 2-4) Antenna Switch Ant. Switch is to share the antenna in TX and RX. It prevents TX sensitivity from degradation by LPF. Also, it protects receive circuit by blocking TX signal to receive end, turning on D101, 102. Flow of the signal in RX is designed to minimize the loss of the signal using the character of series resonance of L105, C111. 2-5) Auto-Power Control This circuit control TX power by detection on the current through R505. The voltage difference from these resistors is amplified by IC501-A and gets the voltage comparing the this signal with the reference voltage from R510, 511 at IC501-B. This voltage difference is kept to stable value by D/A1 changing gate voltage of final Amp. PLL Synthesizer Reference frequency is 14.4 and this oscillated frequency is compensated in temperature. The frequency from VCO is inputted to PLL IC and this inputted signal is divided by the ratio set by data and compared with reference step frequency. Then, the difference comes to IC1 pin5 port. HL series consists of internal charge pump at IC1. Charge pump output turns into DC by PLL LPF R403, 404, 406, C407, 406, 405, so that is can vary VCO control voltage to have set frequency. For TX and RX switch, Q305 and Q306 base switch to control voltage. (TX_EN) Audio and Control circuit IC801 controls all factions of the radio as Microprocessor. It detects outer condition such as function data on frequency, Power supply switching and make it operate correctly. IC606 consists of 250  LPF to function Sub-tone decoding correctly and he output of this filter is amplified at IC606. Then, it goes to IC606 to be changed to logic signal so that Sub-tone decoding is enabled. IC901-A,B, C, and D is TX Audio Amp and limiter. It amplifies the voice signal from C-MIC and has the character of 6dB/Oct Pre-Emphasis. This voice signal is controlled by RV301 for the volume. IC509-C,D is 3 LPF and has the character that reduces to 18dB/Oct. This character minimizes the interference of adjacent channel by voice signal.
