receiving an enabling signal. In this mode it is ableto select a channel and initiate a network by sending enabling
signals to other devices
□A client device is defined as a device operating in a mode in which the transmissions of the device are under
control of the slave. A device in client mode is not able to initiate a network.

(5) For client devices that have software configuration control to operate In different modes (active scanning in
some and passive scanning in others) in different bands (devices with multiple equipment classes or those that
operate on non-DFS frequencies) or modular devices which configure the modes of operations through software,
the application must provide software and operations description on how the software and / or hardware is
implemented to ensure that proper operations modes cannot be modified by end user or an installer. □ Apply,

"Yes please see S I security Description" No Apply (11 apply pls help to provide explanation on it was
