Notes on telephone retrofitting - AH82.70-P-0001-04A

Models 129, 168, 170, 202, 208, 210 

Retrofitting a CTEL with D2B optical wave guide technology is only advisable for vehicles in which D2B ring components are present, and only in combination with an Audio 30 radio.

Vehicles not equipped with these components should, where possible, be retrofitted with conventional CTELs, which are available from Mercedes-Benz accessories.

Vehicles equipped with the TELE AID emergency call system (code 347) or taxi panic call system (code 930) may for safety reasons also only have conventional CTELs retrofitted to them.

Vehicles with code 273 have been prepared for the system installation of conventional CTELs, which are available from Mercedes-Benz accessories. Here it is not  possible to operate the phone via the multifunction steering wheel.

It is more practical to install a CTEL with D2B optical wave guide technology in vehicles (as of approx. 7/99) fitted with a multifunction steering wheel (CTEL operation via keys mounted on steering wheel).

Here, either a radio from the new Audio or COMAND series must be installed.

With regard to an Audio 30 APS radio, it is necessary to ensure that it is a device bearing the following part number A 208 820 .. .. . Older devices with part number A 168 820 .. .. are incapable of conducting the master functions in the D2B ring.

The Audio 30 APS and Audio 10 radios are not equipped with a numeric keypad. This means that it is not possible to operate the CTEL via the radio (refer to owner's manual).
