Siemens VDO Automotive AG SV C BC P2 RF TG IC: 267T-5WK49046 FCC ID:KR55WK49046 User Manual of the Siemens VDO Remote Control Transmitter Type: Designkey I:\POSTZULA\MB_DC\DesignKey\Original_Doku\Func_Designkey.
Siemens VDO Automotive AG IC: 267T-5WK49046 SV C BC P2 RF TG FCC ID:KR55WK49046 General description of the Designkey "Keyless Go" The Designkey incorporates two main functional features. 1. RF remote control system : activation by button press 2. Keyless go system : activation by an external LF-signal source. In both activation modes the Designkey answers with the available RF (radio frequency) interface. For remote control function additionally IR (infra red) communication is in use.
