5.0 OPERATION
5.1 Initial Start-up
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 LED status indicators for proper operation.
If all parameters are correctly set, operation of the radio can be started
by following these steps:
1. Apply primary power to the radio.
2. Observe the transceiver LED status panel (Figure 21) for the proper
indications. Table 4 provides a complete explanation of the LED
functions.
In a normally operating system, the following LED indications will
be seen within 16 seconds of start-up:
•
PWR lamp lit continuously
• SYNC lamp lit continuously
• Remote radio(s) transmitting data (TXD) and receiving data
(
RXD) with the master station

5.2 Performance Optimization
After the basic operation of the radio has been checked, you may wish
to optimize its performance using some of the suggestions given here.
The effectiveness of these techniques will vary with the design of your
system and the format of the data being sent.
