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.
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.
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.

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.
The temperature measuring circuit in the VHF transceiver and the temperature sensor are calibrated in the factory together for optimum temperature measuring accuracy.

Section 3 Operating Instructions 3.1 Control and Indicators Fig. 3-1 Controls and indicators Controls and indicators Description Function Volume control Potentiometer Turning control clock-wise increases volume continuously. ON/OFF switch combined with squelch 3-position rocker switch Postion OFF : VHF transceiver OFF.
Controls and indicators Description Function Channel selector 5-position rotary switch Position A : When the transceiver is powerd up, a brief test routine is performed for the segments of the display. Afterwards the channel frequency 121,500 MHz appears in the display and the transceiver is ready for operation.
Controls and indicators Description Function Store button Pushbutton Briefly pressing the STORE button causes the display frequency to be stored in one of the four memory locations, provided that the channel selector switch is not in position A, but set to one of the four memory positions (1 - 4).
selector switch is in position A. If the channel selector switch is set to one of the stored channel frequencies (any one of switch positions 1 through 4), then the channel frequency stored in that memory location will appear in that display.
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.
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.
