The Iridium PTT handset automatically initiates PTT calling without pressing the PTT call button.

Isolate the issue by disconnecting the RJ45 to DB9 cable from the wireless PTT cradle and the docking station.

Plug the RJ45 cable to the dock. If the Iridium PTT device starts to initiate a PTT call, there is a problem with the cable. The cable will need to be replaced. Contact Beam customer support for assistance.

If plugging the RJ45 cable to the dock does not initiate a call, hook up the DB9 connector to the wireless PTT cradle. If doing this enables the Iridium PTT device to initiate a PTT call, there is something wrong with the cradle. Contact Beam customer support for assistance.

Early wireless PTT cradles were programmed active high. The wireless PTT cradles should be programmed active low to work with Beam Extreme Drive Dock.
