Red and blue indicator LED Charging the battery CHARGING PORT Charging the battery This device has an internal, rechargeable battery. 1. Plug the charger cable into the headset. 2. Connect the charger to a USB power source. The red indicator light will display during charging. If charging does not start, disconnect the charger plug it in again, and retry. Charging the battery fully may take up to 4 hours. 3. When the battery is fully charged, the red indicator light will turn off. Disconnect the charger from the USB power source and the headset. The fully charged battery has power for up to 3-6 hours of talk-time or up to 60 hours of standby time. However, the talk and standby times may vary when used with different devices, settings, and environments. Pairing the headset with compatible phone 1. Make sure your headset is turned off. 2. Push the MFB key for about 7 seconds until the light flashes blue and red. 3. Activate the Bluetooth feature on the phone, and set the phone to search for Bluetooth devices. See the user guide of your phone for instructions. 4. Select the device from the list of found devices. (if pass code is requested enter 0000) 5. If the pairing is successful, the headset’s blue light will flash for 2 seconds then twice every 4 seconds. 6. Once the headset has paired with your device, no password will be needed to reconnect Power ON/OFF & Reconnecting To switch on, press and hold the MFB key for 5 seconds. The blue indicator light will flash quickly for four times. To switch off, press and hold the MFB key for 3 seconds. The red indicator light will flash and a tone will sound. Answer a Call To answer a call, you can press the MFB key, or use the phone keys. To end a call, you can press the MFB key, or use the phone keys.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generate, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:  Reorient or relocate the receiving antenna.  Increase the separation between the equipment and receiver.  Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.  Consult the dealer or an experienced radio/TV technician for help. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. RF exposure warning This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment must not be collocated or operating in conjunction with any other antenna or transmitter.
