2. The starting order delay ensures that colocated masters will not select a frequency
channel at the same time, therefore minimizing the possibility that they choose the
same one. For more information about the starting order, see page 36.
3. The device scans the available frequencies (based on the selected country) and
automatically selects a channel. In the selection process, channels already used by
colocated masters will be discarded at first.
4. The device listens for 60 seconds on the selected channel to detect possible radar
interference.
5. If a radar is detected on the channel, the device returns to the scan process. Otherwise,
it continues its bootup procedure.
6. The device runs normally.
7. If a radar is detected, the device immediately goes back to the scan process to select
another channel.
The boot sequence of client (transmitter) devices is:
1. The device goes through the standard startup procedure.
2. The device roams through the channels in the available frequency bands to locate its
master.
3. When the master is located, the client device runs normally on the selected frequency
channel.
Colocated Systems
When installing colocated systems, you have to carefully plan the position of the devices in
order to prevent radio interference. You can operate many wireless cells in the same
location, provided you follow guidelines relative to frequency band and channel, distance,
wireless passkey, and location.
Regarding frequency channel, you cannot manually select one in the 5.40–5.725 GHz band
in Europe; for the detailed procedure, see page 13.
The wireless passkeys of colocated cells must be different from one another, regardless of
their frequency channels.
