3.11.4 Limitations/Notes
Limitations Please note that there are certain limitations to radio operation if the best
signal selection function is active:

The radios cannot be operated in the main/standby mode as described
in chapter 3.6 Main/Standby Operation (1:1). Both radios must be
operated in active mode
 The USER_OUT2 output cannot be used for remote control of a user
via the management system (UO (user out) GB2PP code)
Note: If the signal strength is nearly identical on both radios, it may happen
that the radio with the weaker signal is connected to the distant station
because of measurement tolerances.
Note: The thresholds are defined for S/N. The corresponding value of
SINAD will be 2 dB higher (SINAD 12 dB value corresponds with S/N 10 dB
value).
