Set up the test equipment as shown below, and apply 14.4V
DC power to the transceiver.
The VX-1210 must be programmed for use in the intended
system before alignment is attempted. The frequency and other
parameters are loaded from the file during the alignment pro-
cess.
In order to facilitate alignment over the complete switching
range of the equipment it is recommended that the channel data
first be uploaded and then stored to disk. Alignment Channel
data should then be downloaded. The original data can be re-
placed at the end of the alignment process.
