as walls, or other electronic devices. The headset is compliant with the Bluetooth
Specification 2.0 + EDR version supporting the following profiles: Headset Profile
V1.2 and Hands-free Profile V1.0.Check with the manufacturers of other devices
to determine their compatibility with this device. There may be restrictions on using

10 meters (30 feet) from your phone and there are no obstructions between the head-
set and the phone, such as walls or other electronic devices.
If you don’t use headset for long time, or maintain the battery well, thus will make the
battery invalid. If so, please contact supplier.

headset and phone is out of 10 meters), the paired headset will connect with the
phone automatically within 20 minutes in the available distance.

This headset is powered by rechargeable battery. The new battery can achieve
the best function only after two or three times fully charged and discharged cycles.
But it eventually will be invalid after being charged and discharged for hundreds of
times.You only can charge the battery with our designated headset charger.
Unplug the charger from the electrical plug and the device when you don’t use it. Do
not leave a fully charged battery to a charger, since overcharging may shorten its
lifetime. If left unused, a fully charged battery will loose its power over time.
Note: Please charge the battery every three months if you don’t use the headset for
a long time.
Use the battery only for its intended purpose. Never use any damaged charger or
battery!
Leaving the device in hot or cold places, such as in a closed car in summer or
winter conditions, will reduce the capacity and lifetime of the battery. Please always
try to keep the battery between 15 ºC and 25 ºC (59 ºF and 77 ºF). A Device with a
hot or cold battery may not work temporarily, even when the battery is fully charged.
The battery performance will be particularly limited when the temperature is below
freezing. Do not dispose the batteries into a fire as they may explode. Batteries
may also explode if damaged. Dispose the battery according to the local regula-
tions. Please recycle the battery when possible. Do not dispose the battery as the
household waste.

5. Terms Interpretation
Pairing: Verify between the two devices (Bluetooth headset and mobile phone)
Connect: The two devices build up connection for communication after been ap-
proved by each other.
Note: Normally, only need to make paring between the two devices once, but con-
nection will not only once (Unless only one device connect with the headset, then it
can connect to that device automatically); Unsuccessful pairing not stand for avail-
able communication, only successful connection can make communication. BT-ET07
stands for the name of the headset mentioned in this manual ,the name will be
showed on the discovered devices list of the mobile phone when making pairing.
