atypically.
• Carry out a reset (see page 24).

®
.
• See information on page 50.
I am receiving error messages from a maintenance pro-
gram after installing ActiveSync
®
.
• The program places the WCESCOMM.LOG file in a tempo-
rary directory defined by the system, which cannot be de-
leted. A respective error message will appear, if another
program attempts to do so.

If a GPS signal continues not to be reported on the screen, in
spite of the correct installation of the system, this can be caused
by the following factors:

Solution:
Change the position of your navigation system and ensure
that unrestricted “sight” of the aerial is not impaired.

• Check the volume setting.
