Pairing Headset to USB Adapter
The headset and USB adapter are supplied paired to each other.
However, if you wish to use a replacement headset with your
existing USB adapter, the units can be paired to each other by the
following method:
1 Ensure your replacement headset is fully charged.
2 Press and hold the power button until the indicator light
flashes red and blue. The headset is now in pairing mode.
NOTE If you don’t see the red and blue flash, press and hold the
power button to turn your headset off. Then press and hold the
power button again until you see the red and blue flash.
3 Place the USB adapter in pairing mode by pressing
and holding the pairing button on the adapter for two
seconds. The pairing light will flash red and blue.
4 When the pairing light on the USB adapter goes solid
blue, the headset and the USB adapter are paired.
NOTE Take caution pairing the USB adapter. Do not press hard.
Please “press” with both fingers rather than push on the USB
adapter to avoid damage to the USB adapter or USB port.
