(alternating) tone will be heard, and the
appropriate indicator lamp will flash. If

fication number or customer information is
not available, the operator may need to
retransmit.
During this time you will hear a beep and
voice contact will be interrupted. Voice
contact will resume once the retrans-
mission is completed. Once a call is
concluded, a beep will be heard and the
respective indicator lamp will stop flash-
ing. The COMAND* system operation will
resume.
