Actual Lead Times for Repair and Maintenance (June 2013):
Transponder: 1-2 week
VHF Voice Radios: 3 weeks
Note for transponders with EEPROM error:
The transponder has to be connected using the original connector TRT800EM (SS). This contains the memory for the ICAO 24 bit address and is part of the certified equipment (it, therefore, may not be opened or modified). The operation of the transponder without the original connector leads to the said error message.
