Alignment
The transceiver must be programmed for use in the
intended system before alignment is attempted. The RF
parameters are loaded from the file during the alignment
process.
In order to facilitate alignment over the complete op-
erating rang of the equipment, it is recommended that the
channel data in the transceiver be preset as per the chart
below.
Set up the test equipment as shown below for trans-
ceiver alignment, and apply 7.5V DC power to the trans-
ceiver.

Installation of the Alignment tool
The “alignment mode” is a software-based protocol,
accessed by an “Alignment Mode” command from the
computer while switching the transceiver on. It is oper-
ated by the alignment tool automatically. During use of
the alignment mode, normal operation is suspended. The
alignment tool program provides all needed operation ca-
pability.
Alignment Sequence
Although the data displayed on the computer’s screen
during alignment is temporary data, it is important you
follow the basic alignment sequence precisely, so that the
displayed data and the data loaded into the transceiver are
identical.
Basic Alignment Sequence
1. Enter the alignment mode
2. Upload data from transceiver
3. Align data
4. Download data to transceiver
