Useful information on pairing
Possible reasons for unsuccessful pairing.
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.
