The FLX 70 headset uses Bluetooth Class 2 with a range up to 10 meters in free line of sight.

	In typical use the range will be one arm distance between the headset and the Bluetooth enabled device.
	When used together with a mobile phone the optimum performance is reached when the user wears the headset on the same side as the mobile. This corresponds to any other headset on the marked.
	The FLX 70 is also equipped with eSCO technology. If your Bluetooth enabled device is equipped with the same technology, both the range and sound quality performance will be enhanced.
	Devices which emit radio frequency in the 2.4GHz band might interfere with and reduce the range of the VMX 100 headset (WiFi,  DECT, Wireless alarms, Microwave ovens, etc.).
