FSG 90F System 1. Safety Information W. Dittel GmbH Section 1 Safety Information Every radio, when transmitting, radiates energy into the atmosphere that may, under certain conditions, cause the generation of sparks. All users of our radios should be aware of the following warning: Do not operate this radio in an explosive atmosphere (petroleum fuels, solvents, dust, etc.
FSG 90F System 1. Safety Information W. Dittel GmbH • Prior to any flight verify proper FSG 90F(X) functions by means of a short communications test. It has to be taken into account that with a faulty antenna or cable this COM test may absolutely turn out positive at the airfield or in short distance to the ground station. But at distances of 2 to 6 miles a faulty antenna and/or cable will cause communication breakdown! • Push-to-Talk keys may stick occasionally.

FSG 90F System 3. Installation W. Dittel GmbH Section 3 3.1 Installation General This section contains instructions and suggestions to be considered before installing the radio FSG 90F(X) into an aircraft. Close adherence to these suggestions will assure more satisfactory performance from the equipment. Information in this section are intended for certified avionics shops only.
FSG 90F System 3. Installation W. Dittel GmbH e) Connect a 50 Ohm Wattmeter and a 20 or 30 dB throughline RF attenuator pad. Key the transmitter and check RF output level (more than 6 Watts carrier, or more than 10 Watts carrier for FSG 90F-H1 model). f) Adjust audio generator to 1,000 Hz (via attenuator for dynamic microphone or directly via decoupling capacitor) connected to Amplified/Carbon Microphone Input With 100 mV rms input, the transmitter shall achieve more than 70% AM. Increase AF input to 1.

FSG 90F System W. Dittel GmbH 3. Installation 3.4.3 Antenna installation Your radio FSG 90F(X) is only as good as the antenna! For operation, a vertical polarized 50 Ohm broadband aircraft COM antenna is required. The antenna must be able to radiate RF energy evenly and omnidirectional: • First of all, look-up the aircraft's manual for antenna installation instructions. • The antenna installation location must be carefully planned. It would be the best to consult the aircraft certifying inspector.
FSG 90F System 3. Installation 3.5 W. Dittel GmbH Airborne wiring Refer to Figures 3-5 to 3-7 of on-board wiring. 3.5.1 General recommendations • Always ensure continuously good, stable electrical contacts, and efficient RF interference suppression of all electrical systems like generator/alternator, ignition etc., especially consider vibration and corrosion effects. Consult the aircraft installation licensing inspector.
