Connect one end of the USB cable to the headset and the other end to the USB connector on a computer, a mobile phone power adapter, or a portable power bank. Troubleshooting Problem: The device cannot be powered on by pressing the power button. Solution: Ensure that the headset is sufficiently charged. Problem: The mobile phone or computer cannot be connected to the Bluetooth headset. Solution: Follow the correct pairing operations and ensure that the device to be paired has the Bluetooth function enabled. Problem: The device cannot play music. Solution: Ensure that the pairing is successful. Problem: A call comes in when I’m listening to music on the headset. When I finish the call, the mobile phone cannot automatically resume music play. Solution: This should be a system software issue of the mobile phone. Try restarting the mobile phone. Problem: The mobile phone cannot find the headset through Bluetooth. Solution:  Ensure that the Bluetooth headset is powered on.  If the Bluetooth headset is powered on but still cannot be located, restart the headset and the mobile phone. Problem: There is always disconnection or noises after the headset and a mobile phone are paired. Solution:  Ensure that the headset is sufficiently charged.  Ensure that there is no barrier between the mobile phone and the headset that might interrupt signal transmission.  Ensure that the distance between the computer or mobile phone and the headset is within 10 meters. Problem: The headset is connected with a mobile phone through Bluetooth, but I cannot listen to the music. Solution:  Ensure that both phone audio and media audio are switched to the paired headset in the Bluetooth setting or the player setting on the mobile phone.  Some mobile phones do not have a complete stereo Bluetooth module, hence no function of music play through a Bluetooth device. You can connect the headset to other mobile phones to check if the headset works. Problem: Some functions of the player are not available on the headset. Solution: Some functions of a player are not supported by the headset. Ensure that you use a compatible player on the mobile phone. Problem: Slow or no response when buttons are pressed. Solution: This might be a result of the disorder of Bluetooth program caused by incorrect button operations. Charge the headset and reset it. Then, disconnect the charging cable and power on the headset for re-pairing. The device should work again. Problem: Unable to mute the device using the headset. Solution: Limited by the Bluetooth agreement, some devices support the mute operation on only one device. In this case, switch the mute function from the device (mobile phone or computer) to the headset. Notice  Long-term exposure to high-volume sounds might result in serious hearing damage.  For your safety, do not use the headset under risky conditions, such as when you are driving or riding.  Ensure that you distinguish the left and right ear buds when you use the headset.

1 INTERTEK TESTING SERVICES RF Exposure The Equipment under Test (EUT) is a Bluetooth headset model Lenovo W520. It is powered by DC 3.7V. For more detail information please refer to the user manual. Antenna Type: Integral antenna. Antenna Gain: 0dBi. The nominal conducted output power specified: 1dBm ±3dB. Test radiated output power: -2dBm ~ 4dBm Modulation Type: GFSK, π/4 –DQPSK and 8-DPSK. According to the KDB 447498: Th e maximun conducted output power specified is 4dBm = 2.51mW The source- based time-averaging conducted output power = 2.51* Duty Cycle mW= 2.09mW The SAR Exclusion Threshold Level: = 3 .0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.480) mW = 9.53 mW Since the source-based time-averaging conducted output power is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing. Transmitter Duty Cycle Calculation Based on the Bluetooth Specification (BT version: 3.0 + EDR), the duty cycle is dependent of packet type (DH1, DH3 and DH5).For one period for a pseudo-random hopping through all 79 RF channels, for DH5: One hop set consists of 5 TX slot and 1 RX slot. Duty cycle = 5 / 6 = 0.833 F CC ID: A5MW520
