The VXR-9000EV must be programmed for use in the in-
tended system before alignment is attempted. The RF pa-
rameters are loaded from the file during the alignment
process.
In order to facilitate alignment over the complete switch-
ing range of the equipment it is recommended that the
channel data in the transceiver is preset as the chart be-
low.

The alignment mode is accessed by "Alignment mode"
command from the computer whilst switching on. And
the alignment tool operates it automatically.
During the alignment mode, normal operation is suspend-
ed. Use the alignment tool program running on PC.

The Alignment Tool Outline
Installation the tool
Install the CE60 (Clone Editor) to your PC.
The re-alignment for VXR-9000EV may use the "Align-
ment" menu of CE60.
Basic sequence
The data displayed in screen of this tool is temporary data,
and there is fear that the consistence of the displayed data
and the data in the transceiver is failure when you do not
keep the sequence which is specified below.
1. Enter the alignment mode
2. Data upload
3. Align data
4. Data download
When finish the alignment one parameter, the tool ask
you "Update this data?" If you select "Yes," the tempo-
rary data is updated. If you select "Yes," the tool down-
loaded data to the transceiver.
Menu of the Tool ( BASIC A
In the Basic Alignment mode, the aligned data written in
the radio will be able to re-align its alignment data. In this
mode, there are many items to align with three point (low
edge, center and high edge) except "VCO," "RX Tune"
and "Mod Balance." The value of each parameter can be
changed to desired position by " " / " " arrow key for
up/down, direct number input and drag the mouse.
To enter the Basic Alignment Mode, select "Basic Align-
ment" in the main menu "Radio." It will start to "Upload"
the written personalized data from the radio and to
"Download" alignment data to the radio. Then pressing
the button "OK" will start the Basic Alignment Mode.
Note; when all items are aligned, it is strongly recommend-
ed to align according to following order. The detail infor-
mation is written in the help of CE60 (Clone Editor).
1. RX VCO Tune Voltage (RX VCO)
2. TX VCO Tune Voltage (TX VCO)
3. PLL Reference Frequency (Frequency)
4. RX Sensitivity (RX Tune)
5. Squelch (SQL)
6. TX Power
7. Modulation Balance <Wide>
8. Modulation Balance <Narrow>
9. Maximum Deviation <Wide>
10. Maximum Deviation <Narrow>
11. Sub-Audio (CTCSS/DCS) Deviation
