Beam PotsDOCK Extreme is a compact docking station specifically designed to support RJ11, Bluetooth and tracking. PotsDOCK allows the Iridium Extreme handset to be connected with an RJ11/POTS interface enabling standard corded, cordless or DECT handset connection or alternatively interfaced with a PABX system presenting standard ring, busy and dial tones like a standard phone network. PotsDOCK Extreme provides extra features such as Bluetooth for voice connectivity along with tracking and alert which can be configured to support periodic polling or emergency alert reporting. The Iridium Extreme handset fits securely in the docking station with an easy click to lock mechanism that can be inserted and removed with a press of a button. It is purposely built to allow you to utilize the SOS emergency, with an inbuilt GPS coupling capability that allows you to connect an external GPS antenna to the dock. PotsDOCK also supports the use of an optional compact BEAM Privacy Handset that can be attached next to the PotsDOCK for added convenience if required. The dock features phone charging, a USB connection for data connection, integrated antenna, data and power connection making it possible to keep all antenna cables and power permanently connected to the dock making it ready for use at all times. Iridium have developed a new Extra LongLife Battery for the Iridium 9575 that is thicker than the standard Litium Ion Battery. DO NOT attach this Extra LongLife Battery to the Iridium 9575 handset and attempt to dock your handset. This will cause damage to the dock and the handset.
