Troubleshooting
1) CK11 repeatedly announces “Power on - Power o”. What should I do?
When CK11 can’t connect to any devices, it will repeat "Power on - Power o" due to its build-in
motion sensor.(Refer to Chapter 4)
a. Please make sure your mobile phones Bluetooth is on before you enter the car so that the CK11
can auto reconnect to your phone.
b. The CK11 will automatically reconnect to the last connected phone once powered on; for other
paired devices, you may need to manually click "Avantree CK11" on the Bluetooth screen of your
phone to reconnect.
c. If you don't want to use the CK11, you can DISABLE this motion sensor function by setting the
power switch to "OFF".
2) Why doesn’t it turn on automatically?
Please note that it will only turn on automatically when the power switch is set to “ON”. If you
manually set the power switch to “OFF“, the device will power o and not automatically turn on
again.
3) How to make a call by voice command?
Step 1: Make sure your smartphone is CONNECTED with WIFI or WLAN/Mobile Data; pair and
connect with CK11 successfully.
Step 2: Activate voice command of your phone by following 2 methods:
a. Press of CK11 once to activate voice command of your phone. You will hear a beep
indicating success. Then you can make a call by voice control (e.g. “call Mom”) or any
other voice commands.
b. You can also activate by “Hey Siri” or “OK Google” for Siri/Google Assistant, but you need
to congure your phone rst. You need to use your voice to complete the setting and it
will be activated by your voice in the future.
