Section 1 GENERAL INFORMATION 1.1 Introduction The following Handbooks describe the VHF-communications transceiver AR 3201 - ( ). The Handbooks DV 28110.03 ( ,, Installation and Operation ‘‘ ) and DV 28110.04 ( ,, Maintenance and Repair ‘‘ ) contain the following sections : Section DV 28110.03 DV 28110.04 1 General Information X X 2 Install[...]

rigid fuselage mounting in all aircraft. The VHF transceiver is designed for compliance with RTCA and EUROCAE airworthiness requirements. 1.3 General description The VHF transceiver is designed as a single-block unit with dimensions in keeping with 58 mm diameter standard instrument size. Mounting is by means of four screws (behind-panel fitting). [...]

The transceiver also contains a stage for monitoring the aircraft supply voltage. This stag e is ON as soon as the transceiver is switched on. Should the aircraft supply voltage drop to 11 V - 10.5 V, the readout will commence flashing. For operation on an 28 V aircraft system a voltage regulator (VR 2011 ) is necessary. In ai rcraft with no power [...]

Section 2 INSTALLATION 2.1 General Installation of the VHF communication transceiver and the battery box depends on the ty pe of aircraft and equipment involved, the instructions given in this section thus being only generally appl icable. 2.2 Pre-instailation check 2.2.1 General Prior to fitting the new system in the aircraft, the units must be ch[...]

The temperature measuring circuit in the VHF transceiver and the temperature sensor are calibrated in the factory together for optimum temperature measuring accuracy. Should the device o r the temperature sensor develop a fault or should the transceiver need replacing, the device w ill need recalibrating according to the instructions as given in Se[...]

3.6 LC display blinking As soon as the operating voltage for the transceiver drops to a value of 10.5 V to 11 V, the d isplay starts blinking to signalize, e.g. in battery operation that the batteries need rechargin g. The display will start blinking in transmitter operation since this situation involves the highest curr ent drain. Since the discha[...]

3.11 Precautions In order to secure a reliable transceiver operation, please note the following precauti ons: a) Before running-up the engines, ensure that the transceiver is switched off. b) Always conduct a verbal pre-flight check. Note that in the vicinity of a flight control, a brok en or shorted antenna cable must not necessarily impair the fu[...]
