Logitech FAQ Resource Central

I'm sure many would like to know how to change the wireless channel for their Logitech devices. Legacy (older) Logitech cordless devices have the option of changing the RF signal from the Logitech software iTouch and MouseWare. Usually switching between channel 1 and channel 2. However, these options are removed with newer Logitech wireless devices.

Here is the breakdown of RF technologies that Logitech wireless devices are using
Legacy wireless devices - 27MHz RF (2 channels)
Current wireless devices - 27MHz Fast RF (2 channels)
Current entry level to high-end wireless devices - 2.4GHz (24 channels)
Current high-end wireless devices - 2.4GHz eQuad (24 channels)
Current high-end wireless devices - 2.4GHz Bluetooth (79 channels)

You can refer to this for the full list of Logitech wireless device range.

As mentioned before, only Logitech's legacy wireless devices allows you to change their wireless channel via the Logitech software. How are we able to do the same for the current ones? Actually it's pretty simple - You just need to re-synchronize them. Every time you re-connect the wireless devices, they will switch to a different channel.
