The docking station keeps beeping and the Iridium handset is not turning on.
This is usually an indication that the Iridium handset has crashed and unfortunately even though the docking station is trying to restart the Iridium handset the phone is not responding. To resolve this problem the Iridium handset must be removed from the cradle, have the battery detached for 10 seconds, replaced and then redocked into the cradle.
