Charging
Your SX-918 comes with a built-in rechargeable battery. Before
using the device for the first time, it is recommended to charge
the battery fully.
1. Connect SX-918 to your USB charger.
a. Red LED indicates the device is charging
b. Blue LED indicates the device is fully charged
2. It takes 1.5-2 hours to charge the battery fully.
3. Please note the input power should be no more than DC5V/1A, to avoid
potential damage to the earphone.
Restore factory settings
Long press the MFB button for about three seconds while charging. The red and blue
LEDs will flash three times to indicate that factory settings have been restored.
Keep your wireless earphone in close proximity to your cell phone. The SX-918 works
much better if it has a clear line of sight to your cell phone. Assuming there are no
obstacles between your cell phone and the SX-918, it has a range of about 10 meters.
Beyond this distance, the connection may become less reliable and sound quality may
deteriorate.

Troubleshooting
Cell phone does not detect the SX-918
Solutions:
1. Confirm that the wireless earphone is turned on and in pairing mode. If the blue
and red LEDs are flashing alternately, the earphones are in pairing mode.
2. If the wireless earphones are turned on but still can't be found on your Bluetooth
device, restart both the cell phone and the wireless earphones and then try again.
After connecting the wireless earphone with your mobile phone, you experience
disconnections or low sound quality.
Solutions:
1. The wireless earphones may have low battery. Recharge the device as needed.
2. There may be an obstacle between your cell phone and the wireless earphone.
Ensure this is not the case. You should be aware that your hand may obstruct
communication if you are holding it against the SX-918. Make sure the line of
communication is clear of any obstruction between these two devices.
3. Your wireless earphone may be out of range. Try moving it closer to your cell
phone for best results.
The wireless earphone has connected successfully, but you can't listen to music.
Solutions:
1. Some cell phones do not have a complete Bluetooth function and stereo
Bluetooth module that are required to listen to music. Please test whether this is
the case by connecting your wireless earphone with another cell phone. If you
can listen to music through the other cell phone, the wireless earphone is
functioning as it should.
2. Check your Bluetooth settings of handsfree mode.
How do you use the wireless earphone to listen to music or chat on computer?
Solution:
If your computer has a Bluetooth function, simply open it and search for the
wireless earphones (SX-918). If your computer does not have a Bluetooth
function, then you will need a wireless adapter in order to connect your computer
to the SX-918. We recommend IVT wireless adapters.

Troubleshooting continued
What is the Bluetooth pairing password?
Solution:
The Bluetooth pairing password is 0000. Only a very small proportion of cell
phones require manual password entry. Most cell phones enter this password
automatically.
The red light is not on when charging
Solution:
If the Bluetooth earphone has not been used for a long time, it may need to be
charged. Try charging the SX-918 for 30 minutes. The red light should come on
again.
