(e. g. portable CTEL, fixed installation, execution in combination with TELE AID). The portable cellular telephone version (A34/6) (code 854) is described in detail below. The telephone radio signals are transmitted and received by the telephone antenna (A2/22).
When the telephone is ready for operation, the reception field strength is indicated in five increments on the display of the COMAND operating, display and control module (A40/3). All the control and useful information signals (e. g. loudspeaker signals during activated handsfree system) are transmitted over the Digital Data Bus (D2B).

^ Automatic disabling of telephone card when the Personal Identifier Number (PIN) is entered incorrectly three times.
