• Then rotate the alignment screw half the number of rotations that was counted to the right again.
Data transmission is now vertically aligned in the exact center.
• Rotate the lower alignment screw to the right until the last green LED on the SIGNAL QUALITY indi -
cator switches off at the mutually opposing device (see figure 4.5). To do this, communication with
the second person is required at the mutually opposing device.
Note: The second person on the mutually opposing device notifies you of their "Signal Quality" indi -
cator.
• Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indi -
cator switches off. Only count the number of rotations.
• Then rotate the alignment screw half the number of rotations that was counted to the right again.
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 QUALITY).
• Rotate the upper alignment screw to the right until the last green LED on the SIGNAL QUALITY indi -
cator switches off at the mutually opposing device (see figure 4.7). To do this, communication with
the second person is required at the mutually opposing device.
Note: The second person on the mutually opposing device notifies you of their "Signal Quality" indi -
cator.
• Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indi -
cator switches off. Only count the number of rotations.
• Then rotate the alignment screw half the number of rotations that was counted to the right again.
Data transmission is now vertically aligned in the exact center.
• Rotate the lower alignment screw to the right until the last green LED on the SIGNAL QUALITY indi -
cator switches off at the mutually opposing device (see figure 4.5). To do this, communication with
the second person is required at the mutually opposing device.
Note: The second person on the mutually opposing device notifies you of their "Signal Quality" indi -
cator.
• Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indi -
cator switches off. Only count the number of rotations.
• Then rotate the alignment screw half the number of rotations that was counted to the right again.
Data transmission is now horizontally aligned in the exact center.
 Repeat the process several times if necessary starting with the second step, until the maximum trans -
mission distance is reached.
NOTICE
Alignment for maximum transmission distance
 The procedure must be carried out for the last time starting with the fourth step for the maximum trans -
mission distance.
Only then are the devices optimally aligned with each other.
The devices are now ready.
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.
