high forces or due to defective assembly. If

the spring contact is assembled incorrectly,

carefully unwind and clip the upper and lower

parts together. Be careful not to trap or bend

the spring contact (32e).

Features
This telephone system is fully integrated with your Mercedes-Benz audio system and steering wheel switches
*
. You can
scroll through the first 99 entries in your phone book and access the entire phone number memory; place, receive, and
terminate calls; change volume; and view call status (such as Ready, Dialing, Incoming Call, Call Active, No Service, Redial,
etc.). Because exact phone features are dependent on the particular audio system installed in your vehicle, detailed oper-
ation is covered in your audio system manual. Please refer to it.
Notes:
• In order for your Mercedes-Benz volume controls to work in conjunction with your Motorola phone (to change ringer
volume or adjust call volume), the vehicle must have either the engine running or the ignition key turned clockwise
to the last position before starting the engine.
• Your phone includes many new features that take additional time to initialize, resulting in increased power up/down
time. Please wait until the phone is completely powered up before using any feature from both the radio and phone
controls.
Finding Information on Phone Features
Your new Mercedes-Benz telephone operates in two modes:
•
Vehicular Mode
—when the phone is inserted and snapped into the privacy cradle in the vehicle
•
Portable Mode
—when the phone is operating as a stand alone device (NOT inserted and snapped into the privacy
cradle in the vehicle)
Most features of your new Mercedes-Benz telephone are available in both modes.
This guide contains basic information on using your phone in Vehicular Mode to place and receive calls.
* Not available on all models.
