Pearl Twin+ handheld transmitter, 868.95MHz SOMMER version, black/chrome 2-command, including SOMMER packaging insert The Pearl Twin+ is primarily intended for use with the 'Codemaster+' transmitter management system because, unlike the Pearl Twin, it can be used to perform the 'remote addition' and 'remote replacement' functions. This means that additional handheld transmitters in the Pearl Twin design can now be prepared in the office with the Codemaster+ and then sent by post, already 'learned', to an underground car park, for example. Remote replacement of Pearl Twin handheld transmitters is also possible in this way. This means that no on-site technician is required, which saves time and money.
