Retrying same channel
If, at the end of the ranging period, the Registered state is not achieved due to
interference or other reasons, the Master unit will retry twice more on the same
channel before moving to another available channel. Should this occur it might take a
number of minutes to establish a link in the Registered state.
Adjusting power settings
The transmit power levels of the installed units must be adjusted to ensure they are
not too high. Excessive power levels may cause saturation of the receivers or false
radar detection (in radar enabled regions), leading to degradation of link performance
and link failure.
To adjust power levels, proceed as follows:
Procedure 5-19 Adjust power levels
1
Consult the report generated by the LINKPlanner tool and note the Transmit
power recommended levels.
2
Set the local unit power equal to the “LOCAL - Max Transmit Power setting
while pointing” value from the LINKPlanner report.
3
Set the remote unit power equal to the “REMOTE - Max Transmit Power setting
while pointing” value from the LINKPlanner report.
4
Access each unit separately.
5
Align the units.
6
Repeat Step 2 and 3 using the values “LOCAL - Max Transmit Power setting
before disarm” and “REMOTE - Max Transmit Power setting before disarm” , if
different than the corresponding “while pointing” values.
7
Reboot the local unit then reboot the remote unit.
8
Disarm the units.
