900 MHz QUAD Channel Base Radio Controller Controls and Indicators

front panel indicate the status of BRC-monitored modules. All LEDs on the BRC
front panel normally flash three times upon initial power-up. A RESET switch
allows a manual reset of the Base Radio. Figure 4 shows the front panel of the
BRC.
