Technical Information
Battery Information
BlueDriver contains a rechargeable
Lithium-Ion battery. These batteries
do not have a “charging memory”
and can be recharged at any time
without changing their life expectancy.
All rechargeable batteries have a
limited life and will gradually lose
their capacity to hold a charge. This
loss of capacity is irreversible. To get
the most from your BlueDriver, the
battery should not be allowed to fully
discharge. If this unit is not in use, the
battery should be recharged at least
every 90 days. The Lithium-Ion battery
in this device is not user replaceable.
Please contact JK Audio or a factory
authorized service center for battery
replacement.
Master(Phone)
or Headset Mode
BlueDriver will first attempt to connect
using the Hands-Free profile, allowing
3.4 kHz (7 kHz if HD Voice is available
on your phone) telecom bandwidth
for a mono full-duplex connection. If
the Hands-free profile is not available,
BlueDriver will attempt to connect in
A2DP stereo streaming mode.
Difference between Profiles
A2DP (Advanced Audio Distribution
Profile): Used for stereo music
streaming.
Headset: Facilitates mono, full-duplex
audio between two paired devices.
Hands-Free: Similar to Headset
profile, but allows the receiving device
more control over the call, such as
volume, accept/reject/end a call.
