AR 3201 - ( ) 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). AII controls and indicators are located on the front panel. The rear panel locates the connector for connecting the transceiver to aircr

AR 3201 - ( ) The transceiver also contains a stage for monitoring the aircraft supply voltage. This stage 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 aircraft with no power circuit (gliders) the battery box (BK 5) is provided. When using the emergency power unit EPU 400 the transceiver can be continued to be o

AR 3201 - ( ) 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 or the temperature sensor develop a fault or should the transceiver need replacing, the device will need recalibrating according to the instructions as given in Section 5, Item 5.7. 2.4 Installation wiring 2.4.1 General Fig. 2-5 illustrates the installation wiring of the VHF transceiver.

This input can only be heard, however, in the RX mode. The possibility of circuiting two units together finds application in aircraft having, for instance, only one transceiver and one NAV receiver. When using the auxiliary audio input, a 680Ω resistor must be switched to GND. When circuiting units toget
