Troubleshooting

I can hear crackling noise.

To receive the best audio quality, it is recommended to wear your headset on the same 
side of the body as your mobile phone.

I can't hear anything in my headset.

•  Ensure the headset is turned on and is properly charged.
•  Ensure the headset is properly paired with the mobile phone.

 

Make sure that the mobile phone is connected with the headset – if it does not 
connect, either refer to the mobile phone's 

Bluetooth

 menu, or press the MFB once 

(see “Using Your Headset” and “Pairing Your Headset with a 

Bluetooth 

Mobile 

Phone”).

I can't connect my headset with mobile phone.

 

Ensure your headset is turned on and is properly charged.

 

Ensure the headset is properly paired with your mobile phone.

 

Ensure your mobile phone’s 

Bluetooth

 feature is activated. Please refer to your 

mobile phone user guide for specific instruction.

 

Ensure the headset is within ten meters' range of your mobile phone and there are no 

obstructions, such as walls or other electronic devices in between.

If the above steps do not solve your problem, please recharge the headset and remove 

your mobile phone’s battery for a while.

I can’t turn off the headset.

Recharge the headset for two seconds then disconnect the charger from the headset. 
The headset now turns off.

The default factory setting is in noise filtering mode

In general condition, users can stick with the default noise filter mode. In case users find 

there’s unstable connection due to mobile network connectivity, users could choose to 

“Mode 2” to strengthen headset reception capability. Users could just press and hold the 

Noise Filter button for 2 seconds while speaking and wait for 2 short beeps are heard. But 

the stability connection is still dependent to mobile network connection.

To return back to default Noise Filter mode, users could press and hold the Noise Filter 

button for 2 seconds while speaking and wait for 1 short beep is heard.

In case users make any alteration, such noise filter mode will remain unchanged for next 

incoming or outgoing calls. When headset is switch off and on again, the noise filter mode 

will be back to default factory setting.
