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 operated at reduced output power (12 V operating voltage) even when aircraft power is down.

When operating the IC mode, the transceiver can be used for intercommunications.

The auxiliary audio input permits input of audio signals from other equipment in the aircraft, however, these auxiliary audio input is standard as of module No. 471 . Up to module No. 470 this feature was only available as an option.

If LCD illumination is required, it can be connected either directly to the operating voltage or to a dimmer.

The standard version can be extened by optional voltage and temperature measuring facilities without affecting the airworthiness of the transceiver.

An optional voltage and temperature measurement circuit permits measurement of either two different voltages or two different temperatures or a single voltage and a single temperature with the aid of two corresponding sensors and two external pushbuttons. The LCD provides indication on pressing the external pushbuttons for approx. 4 seconds. Temperature can be indicated in Fahrenheit or Celsius.

1.4Variants survey

Table 1 -1 surveys the variants of transceiver AR 3201 - ( ). The various variants are not different in appearance, i.e. dimensions, case depth, etc. being the same for all variants. The necessary accessories are given in the List of Accessories at the end of Section 1 for the various variants, all of which have no effect on airworthiness of the transceiver.
