This radio is designed for and classified 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 Com-Net Ericsson 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, 3 kHz to 300 GHz. • American National Standards Institute (C95.3 – 1992), IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields – RF and Microwave. WARNING 4 CAUTION To ensure that your exposure to RF electromagnetic 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 damage 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 an 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” light appears in the display. You can cause the radio to transmit by pressing the “PTT” button. • ALWAYS use Com-Net Ericsson authorized accessories (antennas, batteries, belt clips, speaker/mics, etc). Use of unauthorized accessories can cause the FCC RF exposure compliance requirements to be exceeded. • ALWAYS keep the antenna at least 1 cm (0.4 inches) away from the body when transmitting to ensure FCC RF exposure compliance requirements are not exceeded. To provide the recipients of your 5 transmission the best sound quality, hold the antenna at least 5 cm (2 inches) from mouth, and slightly off to one side. The information listed above provides the user with the information needed to make him or her aware of a RF exposure, and what to do to assure that this radio operates within the FCC RF exposure limits of this radio. Electromagnetic Interference/Compatibility During transmissions, your Com-Net Ericsson radio generates RF energy that can possibly cause interference with other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to do so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as hospitals, aircraft, and blasting sites. 6 OPERATING RULES AND REGULATIONS Two-way FM radio systems must be operated in accordance with the rules and regulations of the Federal Communications Commission (FCC). As an operator of two-way radio equipment, you must be thoroughly familiar with the rules that apply to your particular type of radio operation. Following these rules will help eliminate confusion and will assure the most efficient use of existing radio channels. This will provide a smooth operating radio network. When using the radio, remember these rules: 1. It is a violation of FCC rules to interrupt any distress or emergency message. As the radio operates in much the same way as a telephone "party line", always listen and/or observe the absence of the “BSY” display to make sure that the line is clear before sending any messages. If someone is sending an emergency message, such as reporting a fire or asking for help in an accident, KEEP OFF THE AIR! Emergency calls have priority over all other me…

Receiver Circuit The FM dual-conversion super heterodyne receiver is designed for operation in the 935-941 MHz frequency range. The Receiver has intermediate frequencies (IF) of 115.65MHz and 450kHz. Adjacent channel selectivity is obtained by using two band pass filters, a 115.65MHz crystal filter and a 450kHz ceramic filter. The RX detector is the phase digitizer. 1-1 Receiver Front-end A RF signal from antenna is coupled though the low pass filter/antenna switch, and band pass filter to the input of low noise amplifier Q101. The output of Q101 is coupled through band pass filter to input of 1íst Mixer Z101. Front End selectivity is provided by these band pass filter. 1-2 1íst Mixer The 1íst Mixer is a Double-Balanced-Mixer Z101, that converts a RF signal the 935-941 MHz range to 115.65MHz 1íst IF frequency. The signal on the output of Z101 is provided to the input of 1íst IF amplifier Q102. 1-3 1íst IF The 1íst IF signal 115.65MHz from the output of the 1íst Mixer is coupled through 1íst IF am- plifier Q102 to Crystal filter FL103. The highly selective crystal filter FL103 provide the first portion of the receiver IF selectivity. The output of the filter is coupled through the impedance- matching net work to IF Receiver U101. 1-4 2índ Mixer, 2índ IF filter and 2índ IF amplifier IF Receiver U101 is an one-chip IC for digital communication system. It includes 2índ Mixer, 2índ IF amplifier and Limiter amplifier. With the internal circuits of U101, The 1íst IF signal is amplified and applied to the input of 2índ Mixer. The 2índ local injection frequency 115.2MHz is applied from 2índ local amplifier Q104 to another input of the 2índ Mixer. The 2índ Mixer converts a 1íst IF signal 115.65MHz to 2índ IF frequency 450KHz. Then the 2índ IF signal is applied to Ceramic Filter FL105, which provides the 450KHz selectivity. The output of the 2índ IF filter is applied through 2índ IF amplifier and Ceramic Filter FL104 to Limiter amplifier. This IF signal is amplified and balanced outputs, RXIF and RXIF, are sent to HILLARY.

The transmitter carrier frequencies are same of TX local Injection frequencies. Notch Filter consists of C212, C233, C244, and L210. The output of U203 is applied to Notch Filter that is through an attenuator pad R204-R206. 2-2 Buffer Amplifier and Low Pass Filter, Band Pass Filter The output of attenuator circuit is applied to the Buffer Amplifier U202 that is amplified to +9dBm. The collector voltage for U202 is provided Switch circuit, and is controlled by DPTT. Low Pass Filter and Band Pass Filter consists of C207, C208, C232, L201 and FL201. These filters are controlled by VCO.BAND.SEL signal from the microcomputer (HILLARY:U700). The output of U202 is applied to PA module input through these Filters. 2-3 PA Module The input of the PA Module is amplified to about 2W. B+ (7.5 V dc) is connected U201 through RF chokes L211. The PA Module consists of two stages RF amplifier. The first stage power supply voltage is sup- plied by power control circuit. The second RF amplifier operates in Class-C. This output can be regulated by power control circuit. 2-4 Automatic Power Control The Automatic Power Control circuit samples the output power to the antenna to maintain a constant power level across the band.
