Regarding CDR/PCM:
It can happen that a mobile phone does
not appear in CDR/PCM’s search list due to
unfavourable external conditions. In this
case, you can also start the pairing process
from the mobile phone.
Bluetooth® connection problems
associated with AUX BT may be caused by
the simultaneous running of the telephone
and audio profiles or by the sequence in
which they are connected. In this case, it
may be preferable to deactivate the AUX BT
function by going to ‘DISC/OPTION/SET
DISC/AUX’ to ensure all phone functions are
stable and reliable.
CDR/PCM must not be connected with any
other mobile telephone.
In very rare cases, it can happen that CDR/
PCM forgets the pairing information. As a
result, no connection can be established
between the devices. In this case, delete
the entry left in the car and repeat the
pairing process.
Deleting the device list on CDR/PCM enables
CDR/PCM to find the mobile phone more
quickly.
Regarding the mobile phone:
For the pairing of mobile phones, we
recommend starting the device search
from the mobile phone itself.
The user has 30 seconds to enter the
Bluetooth® code. Otherwise the pairing
process has to be repeated. To do this,
select CDR/PCM from the search list
on the mobile phone again.
There are situations where the mobile phone
will not allow a connection because of an
irregular condition. Restarting the mobile
phone usually returns the mobile phone
to normal operating condition again.
Some phone models allow the user to select
the Bluetooth® profiles supported. Here, too,
profile selections can become forgotten and
the connection can no longer be established.
In most cases this problem can be solved
by recreating the Bluetooth® profiles.
Some phone models respond to a pairing
request by CDR/PCM only when their screen
is active and visible.
In very rare cases, it can happen that the
mobile phone forgets the pairing information.
As a result, no connection can be established
between the devices. In this case, delete
the entry left on the phone and repeat the
pairing process.
On some phone models, each connection
request by the car must be confirmed by
the press of a button. If this confirmation is
not provided, the connection will not be
established.
