If your LINKA won't respond, please determine if the LINKA LED can be turned on.
LED can be turned on
In some cases, your LINKA may have connected to another phone. Make sure that bluetooth on all other phones in the surrounding area have been turned off.
If your LED is on, you may notice that it is solid yellow.
Activate LINKA reset by quickly pressing the power button on your LINKA 20 times. You should now be able to connect to your LINKA.
LED is off
If the LINKA LED is off and cannot be turned on, it is an issue with the battery. Please charge your LINKA with a high-amperage power supply. If you are unable to wake up your LINKA, use a different cable and a different power supply.
