When removing the headset from the base unit, the green link-up indicator on the
front of the base unit will light and the on-line indicator on the headset will flash.
If the green link-up indicator does not light, check the wiring connections on the
base unit and ensure that the power adapter is connected. If the on-line indicator
on the headset does not flash continuously, replace the headset in the base unit
and remove it again.
Battery charging and use
When not in use, place the headset in the base unit to charge the battery. Ensure the link-up indicator is not
lit. If the link-up indicator is lit after placing the headset, remove the headset from the base unit and place
it in the base again. If battery charge is too low, a beep will be heard in the headset every 20 seconds.
