The provided document is a Retrofit-Instructions manual for the Becker Avionics AR6201 VHF-Transceiver, detailing the process of replacing an older AR4201 unit with the newer AR6201.
The AR6201 is a VHF-Transceiver designed for communication in aircraft. It facilitates two-way radio communication, allowing pilots to transmit and receive audio signals. The manual specifically addresses its use as a replacement for the AR4201, implying an upgrade or modernization of existing aircraft communication systems. The transceiver is equipped with an open collector output (P1-24) that indicates its "ON" or "OFF" status, capable of driving an external relay with a maximum current of 100 mA. This feature allows for the synchronization of slave equipment with the transceiver's power state.
While the manual is primarily focused on retrofit instructions rather than a full technical specification, it provides crucial details related to installation and compatibility:
The manual focuses on the installation and verification aspects, which indirectly describe the usage features:
The document outlines several checks and procedures that can be considered maintenance-related, particularly for post-installation verification:
The manual emphasizes the importance of qualified and authorized personnel for troubleshooting and repair in case of any findings during these checks, reinforcing the need for professional maintenance. It also states that user conversions and changes are not permitted, and the device must not be opened or modified beyond the instructions provided, to maintain warranty validity.
