The Planar series impresses with its small and compact design and can be used in many different ways. With up to 17 single-stage keys and an extremely flat design in breast pocket format, this is the smallest station in the NBB product portfolio. Exchangeable AA cells allow maximum functionality. The Planar are equipped with charging contacts, which enable rechargeable batteries to be charged using a charging cradle. The 3.6 V battery developed by NBB itself can also be used as an optional power source. With just one charge, it can power the transmitter for up to 40 hours. The feedback of your machine can be displayed on the integrated 7-segment display.
