II. About the Product
The model of this product is V4 and it is one multifunctional Bluetooth device specially designed
for the motorcycle and skiing enthusiasts. It can be used for the following purposes:
1. One call device for the mobile phone with handfree Bluetooth headset
When going out to ride a motorcycle or ski, this device can automatically and safely use the
inbuilt Bluetooth function to receive an incoming mobile phone call. When there is a call
incoming, you can automatically receive the call after 3s without pressing any key but
riding the motorcycle as usual.
2. One 2-way fully duplex wireless interphone among 4 riders or between a rider and the
passenger on his/her rear seat
Within the sight without any barrier, the max. call distance may reach 1200M/3936miles; on
the roads in a city, the general effective distance is around 500m/1,640miles. Please note that
the actual distance depends on the weather condition, landform, existing barriers, i.e. large
vehicles or invisible buildings, etc..
The 1-way interphone is semi-duplex and thus cannot realize the functions of speaking and
listening at the same time while V4, like a common phone, can realize the communication in
real time.
V4 may be connected among 4 riders or between the rider and the passenger on the rear seat
so that they can communicate with each other easily.
3. One wireless Bluetooth music receiver and speaker
V4 has the functions of EDR and A2DP and one of its important features is that it may be
connected with the mobile phone with A2DP stereo function, MP3 or GPS audio navigator so
as to listen to music. (Of course, this MP3 and GPS audio navigator must have one inbuilt
audio Bluetooth transmission module).
