Operation
The Reciter will need approximately 30 seconds to boot up after power up. When the transceiver is
ready to operate, a voice report (if enabled) can be heard from the front panel speaker, and the
Digital/Analog LED will indicate the current operational mode.
Front Panel Controls and Indicators
The front-panel includes LED indicators, tactile switch buttons, a microphone connector and an USB
(type A) connector, refer figure.1 for details
