The Zebra range of Cradle Locks is designed to work with the TC2x, TC5x and TC7x range of Mobile Devices and SharedCradles with the exception of the TC7x Ethernet SharedCradle. The model of Cradle Lock chosen only works for the range of Mobile Devices for which it has been designed and should not be used for any other device. Each size of the Cradle Lock is available in either a 5 slot or 4 slot version so that the Battery Charger version of the SharedCradle may be accommodated. The Cradle Lock is a low power device and can be powered from the same PSU (Power Supply Unit) that is used to power the SharedCradle. A suitable cable to split the power is provided with each Cradle Lock.
