First time use
the BTS
Charging the battery before use is recommended but
not required. The BTS ships pre-charged, however, the
initial charge may vary. Low battery is indicated by the
status indicator blinking red with an audible tone every
20 seconds.
Charging using the USB cable
Connect the charging cable with the charging port
of the headset below the control panel of the right
earphone. Connect cable to the USB port of a PC or
Mac. The status indicator will be red while charging
and will turn off when fully charged.
