Ä Rotate the lower alignment screw to the right until the last green LED on the SIGNAL QUALITY indica-
tor switches off at the mutually opposing device (see chapter 3.1.1 "Device construction", point 12).
To do this, communication with the second person is required at the mutually opposing device.
ð Note: The second person on the mutually opposing device notifies you of their "Signal Quality" indi-
cator.
Ä Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indicator
switches off. Only count the number of rotations.
Ä Then rotate the alignment screw half the number of rotations that was counted to the right again.
ð Data transmission is now horizontally aligned in the exact center.
Adjust the stationary device if the mobile device displays a reduced received signal level (SIGNAL QUAL-
ITY).
Ä Rotate the upper alignment screw to the right until the last green LED on the SIGNAL QUALITY indica-
tor switches off at the mutually opposing device (see chapter 3.1.1 "Device construction", point 11).
To do this, communication with the second person is required at the mutually opposing device.
ð Note: The second person on the mutually opposing device notifies you of their "Signal Quality" indi-
cator.
Ä Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indicator
switches off. Only count the number of rotations.
Ä Then rotate the alignment screw half the number of rotations that was counted to the right again.
ð Data transmission is now vertically aligned in the exact center.
Ä Rotate the lower alignment screw to the right until the last green LED on the SIGNAL QUALITY indica-
tor switches off at the mutually opposing device (see chapter 3.1.1 "Device construction", point 12).
To do this, communication with the second person is required at the mutually opposing device.
ð Note: The second person on the mutually opposing device notifies you of their "Signal Quality" indi-
cator.
Ä Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indicator
switches off. Only count the number of rotations.
Ä Then rotate the alignment screw half the number of rotations that was counted to the right again.
ð Data transmission is now horizontally aligned in the exact center.
Ä Repeat the process several times if necessary starting with the second step ("Move travel axis or lifting
axis") until the maximum transmission distance is reached.
NOTICE
Alignment at maximum transmission distance!
Ä At the maximum transmission distance, the procedure must be carried out for the last time
starting with the step "Adjust mobile device". Only then are the devices optimally aligned
with each other.
ð The devices are now ready.
NOTICE
At the maximum transmission distance, the SIGNAL QUALITY indicator may be one or two
green LEDs short of end-scale deflection. Data transmission is, however, still active.
