It is not intended to contain a complete statement of all safety precautions, which should be observed by personnel using this or other electronic equipment. Documentation Read, retain and follow instructions before operating the equipment. There is a lot of useful information in the manual, and besides, we spent a lot of time writing it! Environment To reduce the risk of fire or electric shock, do not expose this equipment to rain, moisture, or rye and sodas at the company Christmas party. Refer all servicing to qualified service personnel. Servicing Do not attempt to service this equipment yourself as opening or removing covers can result in a warm tingly feeling and will void the warranty. Refer all servicing to qualified service personnel. 1 Safeguards 2 Terms and Warranty 3 Principle of Operation 4 Installation 5 Operation 6 Control System 7 RF Components 8 Power Supply 9 Maintenance 10 Troubleshooting Safety and First Aid Personnel engaged in the installation, operation, maintenance, or servicing of electronic equipment are exposed to the hazard of high voltage. It is imperative that all safety regulations and precautions are consistently observed. Knowledge of first aid procedures is recommended. The following information is presented as a reference only. The user should ensure that they are trained in proper first aid and the necessary precautions, which may not be contained in this manual, are followed. • At all times, avoid placing any part of the body in series between ground and circuit points, whether power is on or off. • Dangerous voltage may be present in equipment even though power is off. Do not open the cabinet. Refer servicing to qualified service personnel. • It is the duty of all personnel to be prepared to give adequate emergency first aid treatment and thereby prevent avoidable loss of life. • There are three principle degrees of burns, recognizable as follows: • a first-degree burn reddens the skin. • a second-degree burn blisters the skin. • a third degree burn chars the flesh and frequently places the victim in a state of shock accompanied by respiratory paralysis. • Respiratory paralysis can cause death by suffocation within seconds. It is imperative that the approved methods of artificial respiration are initiated immediately and continue until the victim’s breathing is normal. • A muscular spasm of unconsciousness may render the victim unable to break free of the electric power. If this is the case, turn the power off immediately. Do not touch the victim or you may share the same predicament! • If the power cannot be turned off immediately, very carefully loop a dry rope, article of clothing, length of strong cloth or a rolled-up newspaper around the victim and pull the victim free of the power source. Carefully avoid touching the victim or clothing. • Once free of the power source, the victim must be placed in a reclining position and covered with a blanket or newspapers to keep warm. At the first opportunity, enlist help in summoning a doctor. If a doctor cannot be summoned, transport the victim to the doctor or a hospital. Be sure the victim is kept well covered and warm while awaiting professional treatment. 1 Safeguards 2 Terms and Warranty 3 Principle of Operation 4 Installation 5 Operation 6 Control System 7 RF Components 8 Power Supply 9 Maintenance 10 Troubleshooting Operating Safeguards Load Impedance It is a known fact that our FM equipment enjoys 50-ohm load impedances. So much so, that it is imperative you maintain 50-ohm impedances throughout your system. In return, your equipment will provide you with maximum power transfer to the antenna and decreased reflected power heading back towards the amplifier pallets, reducing the amount of magic smoke that gets let out of the equipment. Before anything is turned on, ensure that there is a 50-ohm path from the output of each stage to the input of the next, all the way to the antenna. Operating Warnings Our FM equipment is designed to reliably generate a specific RF output power level. Failing to adhere to overdriven amplifier, high reflected power, and high temperature, and other war…

Test Temperature Standard temperature: 20⁰C +/- 5⁰C as per BETS-6 [section 3.3] Actual temperature: _______20_⁰C_____ 3. Carrier Power Definition The power output rating of the transmitting equipment is the carrier power at which the transmitting equipment may be operated continuously into the test load. Requirement (FCC) - 47CFR Part 2, Subpart J, 73.1560 (b) (b) FM stations. Except as provided in paragraph (d) of this section, the transmitter output power of an FM station, with power output as determined by the procedures specified in §73.267, which is authorized for output power more than 10 watts must be maintained as near as practicable to the authorized transmitter output power and may not be less than 90% nor more than 105% of the authorized power. FM stations operating with authorized transmitter output power of 10 watts or less may operate at less than the authorized power, but not more than 105% of the authorized power. Requirement (Industry Canada) - BETS-6 [section 6.1.3] The transmitting equipment shall be capable of being adjusted to deliver the rated power output when the AC input voltage varies by 5% from the rated value. Adjustment of the power output of the transmitting equipment shall permit operation over a range of at least from 50% to rated power output. Method An average reading RF wattmeter is placed between the transmitter output (directly on the directional coupler’s N connector on the back panel) and the 50 Ω dummy load. While observing the external wattmeter, the AC mains voltage and output power is varied to ensure that is adjustable over the proper ranges. Measurement Rated AC voltage 208 Vac. The rated carrier output power is 500 watts at -5% Vac. The rated carrier output power is 500 watts at rated Vac. The rated carrier output power is 500 watts at +5% Vac. Specified RF power …
