(Fig 2: J1502 connection for the modulation adjustment)
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.
[Important]
In order to facilitate alignment over the complete switching range of the equipment it is
recommended that the channel data in the transceiver is preset as the chart below.

The alignment mode is accessed by “Alignment mode” command from the computer whilst
switching on. And it is operated by the alignment tool automatically.
During the alignment mode, normal operation is suspended. Use the alignment tool program
running on PC.

Connect the positive lead of the DC voltmeter to the test point TP1007 (VCV) on the RF-Unit,
as indicated in the figure, and the negative lead to chassis ground.

Set the transceiver to the high band edge frequency channel, then adjust coil L1017 on the
Unit for 4.25V on the voltmeter.

Next select to the low edge frequency channel and confirm above 0.80V to 1.50V on the
voltmeter.

PLL Reference Frequency
With the wattmeter, dummy load and frequency counter connected to the antenna jack, and
select band center frequency channel, key the transmitter and adjust VR1001 on the RF-Unit, if
necessary, so the counter frequency is within 100 Hz of the channel center frequency for the
transceiver version.
