IM20-VT3H040CT DE DANIELS ELECTRONICS VT-3H040 VHF Enhanced Transmitter Instruction Manual 1 1 GENERAL 1.1 Introduction The VT-3H040 transmitter is a low power, synthesized FM transmitter capable of operating in 20 kHz or 25 kHz channels and within one of two bands: 29 MHz to 38 MHz or 38 MHz to 50 MHz. The transmitter is rated for continuous duty at an RF output power of 3.0 Watt. The RF output power level is preset at the factory. A modular design allows each of the transmitter's modules; MT-3 Transmitter Main Board, MT-3 Audio Processor, VT-3H040 Amplifier and OS- 3H040 Synthesizer to be individually assembled and tested. This facilitates construction, tuning, maintainance as well as troubleshooting procedures. The synthesizer module can be programmed to have up to 16 channels exclusive to one frequency band. The VT-3H040 Transmitter is designed to interface with Daniels Electronics' MT-3 Repeater System while maintaining MT-2 System compatibility. Both radio systems are characterized by dependable, low maintanence performance under the most severe environmental conditions. 1.2 Manual Organization The organization of this manual reflects the modular makeup of the VT-3 product line. Each module is fully described within its respective submanual, all of which are contained within this document. In general, each submanual contains: 1. A functional description and specification summary, 2. a detailed technical description (Theory of Operation) and 3. assembly, setup and alignment procedures relevent to that particular module. The module manuals are as follows. Note: material presented in a given "sub-manual" may include information related to other module versions not dir…

iii RF Exposure Warning Exposure to radio frequency (RF) energy has been identifi ed as a potential environmental factor that must be considered before a radio transmitter can be authorized or licensed. The FCC has therefore developed maximum permissible exposure (MPE) limits for fi eld strength and power density, listed in FCC 47 CFR § 1.1310. The FCC has furthermore determined that determination of compliance with these exposure limits, and preparation of an Environmental Assessment (EA) if the limits are exceeded, is necessary only for facilities, operations and transmitters that fall into certain risk categories, listed in FCC 47 CFR § 1.1307 (b), Table 1. All other facilities, operations and transmitters are categorically excluded from making such studies or preparing an EA, except as indicated in FCC 47 CFR §§ 1.1307 (c) and (d). Revised FCC OET Bulletin 65 (Edition 97-01) provides assistance in determining whether a proposed or existing transmitting facility, operation or device complies with RF exposure limits. In accordance with OET Bulletin 65 and FCC 47 CFR § 1.1307 (b), this Daniels Electronics Ltd. transmitter is categorically excluded from routine evaluation or preparing an EA for RF emissions and this exclusion is suffi cient basis for assuming compliance with FCC MPE limits. This exclusion is subject to the limits specifi ed in FCC 47 CFR §§ 1.1307 (b) and 1.1310. Daniels Electronics Ltd. has no reason to believe that this excluded transmitter encompasses exceptional characteristics that could cause non-compliance. Notes: • The FCC’s exposure guidelines constitute exposure limits, not emission limits. They are relevant to locations that are accessible to workers or members of the public. Such access can be restricted or controlled by appropriate means (i.e. fences, warning signs, etc.). • The FCC’s limits apply cumulatively to all sources of RF emissions affecting a given site. Sites exceeding these limits are subject to an EA and must provide test reports indicating compliance. RF Safety Guidelines and Information Base and Repeater radio transmitters are designed to generate and radiate RF energy by means of an external antenna, typically mounted at a signifi cant height above ground to provide adequate signal coverage. The following antenna installation guidelines are extracted from Appendix A to OET Bulletin 65 and must be adhered to in order to ensure RF exposure compliance: Non-building-mounted Antennas: Height above ground level to lowest point of antenna ≥ 10 m or Power ≤ 1000W ERP (1640 W EIRP) Building-mounted Antennas: Power ≤ 1000 W ERP (1640 W EIRP) The following RF Safety Guidelines should be observed when working in or around transmitter sites: • Do not work on or around any transmitting antenna while RF power is applied. • Before working on an antenna, disable the appropriate transmitter and ensure a “DO NOT USE” or similar sign is placed on or near the PTT or key-up control. • Assume all antennas are active unless specifi cally indicated otherwise. • Never operate a transmitter with the cover removed. • Ensure all personnel entering a transmitter site have electromagnetic energy awareness training. For more information on RF energy exposure and compliance, please refer to the following: [1] FCC Code of Regulations; 47 CFR §§ 1.1307 and 1.1310.
