After the alignment using the viewfinder, make adjustment
with the voltmeter for more accurate optical alignment.
Set the voltmeter range to 5 to 10 VDC.
After checking the receiving level of optical axis by using
the Level indicator LED, make sure to make fine
alignment for both transmitter and receiver with voltmeter
to achieve a monitor output level of "Excellent".
Adjust the horizontal and vertical angles while checking
the light receiving status by Alarm indicator LED on the
pairing receiver.
Perform rough alignment of the horizontal angle.

Look into the viewfinder and perform fine alignment of the
horizontal and vertical angles using the alignment dial.
Make the settings of 1 to 4 to the lower as well.

Insert the voltmeter's positive pin into
the positive terminal of the monitor
jack, and the negative pin into the
negative terminal.
Mount a beam blocking plate to the lower
unit and then start optical alignment from
the upper unit.
Beam blocking plate is attached on the
back of the cover.
Return the beam blocking plate to the
cover after use.
