5.1 Initial Startup & Checkout
In-service operation of the transceiver is completely automatic. Once
the unit has been properly installed and configured, operator actions are
limited to observing the front panel LED indicators for proper operation.
If all parameters are correctly set, operation of the radio can be started
by following these steps:
1. Apply DC power.
2. Observe the LED status panel for proper indications (Table 10).
3. If not done earlier, refine the antenna heading of the station to maxi-
mize the received signal strength (RSSI) from the Master Unit. The
RSSI command can be used to display signal strength. Turn the
antenna heading slowly so that the RSSI display can be updated.
NOTE: The RSSI function limits the maximum displayed signal
strength to –60 dBm.
