2.1 Battery Charging and Usage

2.1.1 Battery Charging

This device contains a rechargeable Li-Polymer battery. First-time charging needs about 4 hours. Later-on

recharging needs 2-3 hours. Detailed charging procedures are as follows:

1. Referring to Figure 2, connect the charger cable to the device.

2. Plug the car charger into the cigarette lighter in your car to start charging. Both the Red and Blue LEDs will be

on during charging. Once the Red LED turns off, the battery is fully charged and you should disconnect the

charger.

Figure 2 Battery charging

You can also use the USB charging cable to charge the device on your PC, which will take longer to charge as the

power output of the USB port is lower than it is with the car charger.

Once the battery is fully charged, it will provide up to 8 hours of talk time and up to 600 hours of standby time.

When the battery is low, the device prompts “Battery low” once every 2 minutes and the Blue and Red LEDs

alternate every 3 seconds, and then you need to charge the battery as described above.

Note that, over-charging will reduce battery life. If a fully charged battery is left unused, it will lose power over time. Extreme temperature (either too hot or too cold) will also affect its ability to charge, capacity, and lifetime.

2.2 Mounting your Handsfree

This Handsfree device can be easily mounted inside the car by using the Sun-Visor Clip to fix the product on the

sun-visor over the driver’s seat.

connected to it.

2. Initiate connection request from the Handsfree:

When the handsfree is in standby mode, which means no Bluetooth connection exits, press button

connect the device last connected to it. Once the connection is established, start to connect the second to the

last device. Note that, if your handsets are not the last or second to the last connected handsets, you need to

make connections from the handset side.

that you have to wait one connection is completed before launching the other.

. 13

BTHF304 User Manual

When two handsets are connected with the handsfree, the one which is connected to the handsfree first works as the

primary device and the other is the secondary device. Only when the first handset is disconnected from the

handsfree, the primary/secondary relation can be handed over.

Any operation initiated from the handsfree side, such as redialing and voice dialing, will only be applied to the

primary device.

Operations initiated from either handset shall be applied to the handsfree as normal.

2.8.2 Call Operations

When two handsets are both connected to the Handsfree:

1. If only one handset receives a call, the call will be transferred the handsfree and all call operations will be the

same as the case of single connection.

2. If both of the connected handsets receive calls at the same time, only the first call will be transferred to and

controlled by the handsfree (call waiting and conference call are also controlled by the handset which receives

the first incoming call). Unless the first call is terminated, and press call button

on another handset to the device, the second call will stay on that handset.
