Charging the BLUETREK® DUO Stereo
Please connect the charger to the headset and to the main. During the charge, the
indicator light is red. The indicator light will turn off when the charge is complete.
During subsequent charges, the charging should take approximately 3 hours.
When you hear a low-tone beep in your headset at regular intervals, and the indica-
tor light flashes in red, your headset needs to be recharged.
