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 for proper indications.
Table 4
provides an explanation of the LED functions.
In a normally operating system, the following 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
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.
Complete instructions for using the commands referenced in this manual are
provided in
“RADIO PROGRAMMING” on Page 21 .
