4. How to connect Bluetooth earphone to your computer?
Answer:If your PC comes with a Bluetooth function, you can start to
search the on-state headset after installing the correct driver.
If your PC does not compact with Bluetooth, you will need to download
and install the Bluetooth adapter software (IVT) to be able to use
Bluetooth on your PC. Computers with XP system can identify Bluetooth
adapter and it does not need driver, whilst the XP built-in adapter can only
transfer files but not audio signal, so you will need to install the IVT
software from the CD to enable audio transmission.
5.How long can the devices part from each other while using?
Answer:The sensing distance between Bluetooth earphone and mobile
phone or adapter is 10 M. Within that range, the connection stays sturdily
when there is no obstruction between devices. But there will be light noise
or distortions on calls if the devices are set apart outside the sensing
range.
6. What is the pairing password for the Bluetooth headset?
Answer:The default Bluetooth pairing password is 0000. Most phones fill
that password automatically, but you might need to manually enter the
password in some cases.
7.The indicator on the headset shows no red light during charging?
Possible reason: The device has not been powered for a long time.
Solution: Keep the device on charging for 30 minutes, the red light should
reappear on the indicator.
Caution: Over charging or put the headset within enclosed environments
like within a car, the battery life and capacity would be reduced.
