OPERATION 3.1 INTRODUCTION This section contains information concerning the operation procedures for the BK Radio DPH Flex•Mode Series handheld VHF radios. Information on installation and programming is contained in Section 2 of this manual. WARNING DO NOT OPERATE THE TRANSMITTER IN CLOSE PROXIMITY TO BLASTING CAPS WARNING DO NOT OPERATE THE RADIO IN AN EXPLOSIVE ATMOSPHERE (PETROLEUM FUELS, SOLVENTS, DUST, ETC.). RF ENERGY EXPOSURE AWARENESS AND CONTROL INFORMATION, AND OPERATIONAL INSTRUCTIONS FOR FCC OCCUPATIONAL USE REQUIREMENTS BEFORE USING YOUR PORTABLE 2-WAY RADIO, READ THIS IMPORTANT RF ENERGY AWARENESS AND CONTROL INFORMATION AND OPERATIONAL INSTRUCTIONS TO ENSURE COMPLIANCE WITH THE FCC’S RF EXPOSURE GUIDELINES. NOTICE: This radio is intended for use in occupational/controlled conditions, where users have full knowledge of their exposure and can exercise control over their exposure to meet FCC limits. This radio device is NOT authorized for general population, consumer, or any other use. This 2-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communications between two or more users over a distance. It uses radio frequency (RF) energy or radio waves to send and receive calls. RF energy is one form of electromagnetic energy; other forms include electric power, radar, sunlight and x-rays. RF energy, however, should not be confused with these other forms of electromagnetic energy, which when used improperly can cause biological damage. Very high levels of x-rays, for example, can damage tissues and genetic material. The energy levels associated with radio waves from portable 2-way radios, when properly used, are not great enough to cause biological damage. Experts in science, engineering, medicine, health and industry work with organizations to develop standards for exposure to RF energy. These standards provide recommended levels of RF exposure for both workers and the general public. These recommended RF exposure levels include substantial margins of protection All 2-way radios marketed in North America are designed, manufactured and tested to ensure they meet government established RF exposure levels. In addition, manufacturers also recommend specific operating instructions to users of 2-way radios. These instructions are important because they inform users about RF energy exposure and provide simple procedures on how to control it. Please refer to the following WEBSITES for more information on what RF energy exposure is and how to control your exposure to assure compliance with established RF exposure limits. http://www.fcc.gov/oet/rfsafety/rf-faqs.html http://www.osha.gov/SLTC/radiofrequencyradiation/index.html FEDERAL COMMUNICATIONS COMMISSION REGULATIONS The FCC rules require manufacturers to comply with the FCC RF energy exposure limits for portable 2- way radios before they can be marketed in the U.S. When 2-way radios are used as a consequence of employment, the FCC requires users to be fully aware of and able to control their exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a product label directing users to specific user awareness information. Your BK Radio 2-way radio has a RF exposure product label. Also, your BK Radio user manual, or product manual, or separate safety booklet includes information and operating instructions required to control your RF exposure and to satisfy compliance requirements. COMPLIANCE WITH RF EXPOSURE STANDARDS Your BK Radio 2-way radio is designed and tested to comply with a number of national and international standards and guidelines (listed below) for human exposure to radio frequency electromagnetic energy. This radio complies with the IEEE and ICNIRP exposure limits for occupational/controlled RF exposure environment at operating duty factors of up to 50% transmitting and is authorized by the FCC for occupational use only. In terms of measuring RF energy for compliance with the FCC exposure guidelines, your radio radiates measurable RF energy only while it is transmitting (during talking), not when it is receiving (listening) or in standby mode. Note: The approved batteries supplied with this radio are rated for a 5-5-90 duty factor (5% talk-5% listen - 90% standby), even though this radio complies with the FCC occupational RF exposure limits and may operate at duty factors of up to 50% talk. Your BK Radio 2-way radio complies with the following RF energy exposure standards and guidelines: United States Federal Communications Commission, Code of Federal Regulations; 47 CFR §§ 1.1307, 1.1310, 2.1091 and 2.1093 American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1992 Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition RF EXPOSURE COMPLIANCE AND CONTROL GUIDELINES AND OPERATING INSTRUCTIONS To control your exposure and ensure compliance with the occupational/controlled environment exposure limits always adhere to the following procedures. Guidelines: • Do not remove the RF Exposure Label from the device. • User awareness instructions must accompany device when transferred to other users. • Do not use this device if the operational requirements described herein are not met. Operating Instructions: • Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push the Push- To-Talk (PTT) button. To receive calls, release the PTT button. Transmitting 50% of the time, or less, is important because this radio generates measurable RF energy exposure only when transmitting (in terms of measuring for standards compliance). • Hold the radio in a vertical position in front of face with the microphone (and the other parts of the radio, including the antenna) at least one inch (2.5 cm) away from the nose. Keeping the radio at the proper distance is important because RF exposures decrease with distance from the antenna. Antenna should be kept away from eyes. • When …

BK RADIO Page 4-1 THEORY OF OPERATION 4.1 INTRODUCTION This section contains the theory of operation for the DPH Flex•Mode radio. To help you understand the operation of the equipment, refer to the schematic diagrams in Section VI of this manual. 4.2 EQUIPMENT DESCRIPTION The DPH Flex•Mode radio is a self-contained VHF FM radio operating in the 148 MHz to 174 MHz band. The radio is digitally synthesized and uses a single crystal for frequency control. An EEPROM is incorporated for the storage of channel frequency, Code Guard™ values, Automatic Numeric Identifier (ANI), hardware tuning, and other operating information. Connectors are provided on the side of the radio for the external antenna, microphone, speaker, and other optional accessories. Twist-off battery packs are also available. The 16 channels are fully programmable. The radio is shipped with stop pins so that the channel selector switch can be moved to limit the number of positions to any value. 4.3 THEORY OF OPERATION Circuitry for the DPH Series radio comprises five major circuits: • The RECEIVER, which consists of RF preselectors, RF amplifier, mixer, IF filters, IF amplifiers, FM IF IC, and noise squelch circuitry. • The TRANSMITTER, which consists of a power amplifier, harmonic filter, antenna switch, and power control circuitry. • The SYNTHESIZER, which consists of a voltage controlled oscillator (VCO), VCO buffer, prescaler buffer, prescaler, synthesizer IC, reference oscillator, loop filter, and acquisition aid bit circuit. • The SYSTEMS area, which consists of a microprocessor, microprocessor oscillator, EEPROM, signaling and switching, front-end tuning amplifier, 5V and 8.2V regulators, transmitter audio processing, deviation compensation, squelch threshold circuitry, and receiver audio processing. • The Digital Signal Processing (DSP) area, which consists of a Digital Signal Processor, Flash Memory, CODEC, TCXO, 1.8V and 3.3V regulators. 4.3.1 Receiver The receiver is a dual-conversion design with intermediate frequencies of 16.9 MHz and 455kHz. RF signals received at the antenna pass through the antenna switch and front end. The front end consists of an amplifier and two microprocessor-tuned bandpass filters. The front end amplifies the receive frequency and attenuates image, half IF, and other frequencies that degrade receiver performance. RF signals from the front end enter a mixer that converts them to 16.9 MHz. The 16.9 MHz IF signal passes through two crystal filters that provide adjacent channel selectivity. The IF amplifier then amplifies the signal and couples it to the 455 kHz IF integrated circuit. The 455 kHz IF IC consists of a mixer, limiter, demodulator, and squelch circuit. The 16.9 MHz signal enters the mixer and is converted to a 455 kHz IF signal. A ceramic filter at 455 kHz provides more adjacent channel selectivity. The signal is then amplified by the limiter and demodulated. Audio processing is then done on the options board. Filtered audio noise is used to provide a squelch indication. Theory of Operation DPH Series VHF Radio Page 4-2 BK RADIO A. RF Preselectors The preselectors provide greater than 75 dB of attenuation at the image frequency. Both bandpass filters are varactor tuned, which allows a wide frequency spread. Overall, the preselectors exhibit a bandwidth of 4.5 MHz. The preselectors consist of L2, L3, L4, L5, and associated circuitry. Figure 4-1 Receiver block diagram B. RF Preamplifier The RF amplifier is a single-transist…
