The radio detectors DOW1171 and SMF6120 have a status indicator.
In configuration mode the status indicator uses flashing sequences to indicate the
field strength.
This table lists all possible status indications:
Flashing sequence of status

1x/s
1x / 2 s
3x / 2 s
1x long / 2 s
4x / s*
3x / s*
2x / s
