The CDR-31 can distract your attention from
the traffic conditions. You could cause an ac­cident and place yourself and others in dan­ger.

f Always devote your complete attention to the

traffic situation.

f Only operate the CDR-31 when traffic and dri-

ving conditions are appropriate.

f Only change discs while the vehicle is stationa-

ry.

f Set the volume to a level that allows you to

hear important sounds outside the vehicle e.g.
horns, sirens and alarms.

d Warning!

The CDR-31 is a Class 1 laser product. There
is a risk of damage to the eyes from invisible
laser radiation if the housing is opened or if
it is faulty or damaged.

f Do not open the housing.
f Do not remove any covers.
f Do not carry out any repairs to the device. If

necessary, the device must be repaired by a
suitably qualified repairer.

Protective circuits

The CDR-31 includes protective circuits that pre­vent damage to the device as far as possible:

– If the supply voltage is too low or too high, or

if the CDR-31 becomes too hot, the CDR-31
will switch off automatically.

– CD mode will be switched off if the CD drive

overheats. It is possible to switch to another
sound source until the CD drive has cooled
down.

General instructions 3

Introduction to operation

Operating functions using the touchscreen

The screen of the CDR-31 is a colour touchscreen
which allows you to operate the menus easily and
comfortably.

You can operate all menu functions, list entries
and text input fields, as well as the arrow symbols
by gently touching the appropriate place on the
screen.

Operating functions with the right knob

In addition to touchscreen operation, you can ope­rate all menu functions, list entries and input fields
using the knob on the right:

f Turn the right knob to mark the menu item.
f Press the right knob to select the menu item.

d Caution!

Risk of damage. The CDR-31 contains high
quality electronic components which require
careful maintenance and care.

Please note the following:

– The screen is easily scratched.

– Do not spray liquid onto the appliance. If liquids

get inside the appliance these could destroy it.

f Carefully clean your CDR-31 from time to time

using a soft, dry and clean cloth (microfibre
cloth) or a cleaning brush.

f Do not lean heavily on the surface when clea-

ning the appliance.

f Never use cleaning solutions such as methyla-

ted spirit, white spirit, benzene, acetone or al­cohol (ethanol, methanol or isopropanol) or
any abrasive.

f Wipe away fingerprints using a slightly damp

cloth or a mild cleaning agent.

f Never spray cleaning agents or other liquids di-

rectly onto the screen. Dampen a cloth and
then carefully wipe the screen.

f Never open the CDR-31 yourself in the event of

a fault! Take the faulty appliance to be repaired
by a competent specialist repairer. We recom­mend that you use a Porsche Partner for this
work as this will ensure that trained workshop
staff and the necessary parts and tools will be
available.

If it is extremely cold, it will take a few minutes for
the screen to reach maximum brightness.

function is deactivated, you may hear another pro­gramme whilst the radio is switching to an alterna­tive frequency.

1. Press "RDS" to switch on RDS ( ).

2. Select "Regional (FM)".

The regional function is now switched ON

Tips for use of compact discs (CD)

Dirty or scratched CDs may cause audible gaps
during playback. Please observe the following ad­vice to ensure optimal sound reproduction:

– Always hold the CD at the edge. Never touch

the surface of the CD and ensure it remains
clean.

– Do not attach anything to the CD.

– Protect CDs from sources of heat such as ra-

diators.

–Clean CDs before use with a generally available

specialist cleaning cloth, working from the cen­tre outwards. Cleaning solutions such as ben­zene, white spirit or other commercially avai­lable cleaning products and antistatic sprays
should not be used.

Tips for use of CD-ROMs and MP3 CDs

– The CDR-31 can be used to play back audio

CDs and MP3 CDs. MP3 CDs are data CDs that
can also include folders.

– Acceptable bit rates for MP3 mode: fixed and

variable bit rates up to 320 kBit/s.

– Acceptable sampling rates for MP3 mode:

24 kHz to 48 kHz

26 CD mode

– A delay may occur when reading MP3 discs,

depending on the format used and amount of
data stored.

– ID3 tags are not supported, instead the filena-

me is displayed in MP3 mode.

– The CDR-31 can also read copy-protected au-

dio CDs, provided that the copy protection me­thod was known at the time of manufacture. It
may not be possible to read CDs protected
with newer copy protection algorithms.

– CDs with parts of the CD-ROM that do not cor-

respond to the audio CD standard may not play
on the system.

– CDs with more than 700 MB data volume can

also cause playback problems.

– For multisession CDs, the content of the first

session will determine how the CDR-31 proces­ses the CD. All other sessions will be ignored.

AUX (optional)

Depending on the equipment fitted in the vehicle,
a 3.5mm stereo jack socket may be located in the
storage compartment in the centre tunnel. This
can be used to connect an external sound source.

d Important

Using the headphone output can lead to un­desirably high volumes.

Headphone outputs from external sound sources
have a very low volume level. If the CDR-31 is
therefore set to a very high volume to compensa­te, this may lead to unintentionally loud volume if
another sound source is activated, or if a traffic
announcement is broadcast.

f Therefore, the LINE-OUT output on the external

source should be used instead of using the
headphone output, as this will ensure an appro­priate volume level.

If the device does not have a LINE-OUT output:

1. Switch off Traffic Announcements.

2. Switch off the mobile telephone system.

3. Reduce the volume on the CDR-31 before acti­vating another sound source.

Connecting external sources

If applicable, refer to the instruction manual for the
external sound source on how to connect the
sound source.

1. Press the CD AUX button repeatedly until AUX

mode is activated.

2. Set the CDR-31 volume to the minimum set­ting.

3. Connect the external sound source using the
AUX socket.

4. Set the volume on the external sound source
to a medium level.

5. Start playback on the external sound source.

6. Carefully adjust the volume of the CDR-31 in
small steps until the desired volume is rea­ched. If necessary, increase the volume on the
external sound source.

d Warning!

Operating the telephone whilst driving can
distract your attention from the traffic condi­tions. You could cause an accident resulting
in injury to yourself and others.

f Always follow the traffic regulations of the

country you are in when using mobile commu­nication devices whilst driving.

f Where the use of communications devices

whilst driving is permitted, these should only
be operated when traffic conditions are appro­priate.

devices to prevent unauthorised access to the
CDR-31.

Up to three mobile telephones can be authorised
for use with the CDR-31. Once authorised, a mobi­le telephone can be connected to the CDR-31 in
order to make use of the telephone functions that
it provides.

Connecting an authorised mobile telephone

The CDR-31 will detect when a previously authori­sed mobile telephone is in range and will send a
connection request to the mobile telephone. If se­veral authorised mobile telephones are in range,
then the CDR-31 will connect with the most re­cently connected mobile telephone. If it is not pos­sible to connect to this mobile telephone, then the
previously connected mobile telephone will be
searched for.

f Accept the connection request on the mobile

telephone. Follow the prompts displayed on
the mobile telephone (refer to the instruction
manual for the mobile telephone).

The CDR-31 should connect automatically to
the mobile telephone.

Note

With certain mobile phones the connection re­quest has to be confirmed by the CDR-31 on the
mobile phone. This may even have to be done se­veral times, e.g. before transferring the contacts.
To avoid these prompts you can authorise the
CDR-31 in the device list on your mobile phone. On
your next attempts the connection will be made
automatically without query. Please refer to the
mobile telephone instruction manual for further in­formation.

External authorisation

If the CDR-31 cannot find your mobile telephone,
or the authorisation process repeatedly fails when
initiated by the CDR-31, then the authorisation can
be initiated from the mobile telephone.

1. If another mobile telephone is connected to the
CDR-31, switch off Bluetooth

each authorised mobile phone. The respective
Contacts can then only be used when the CDR-31
is connected to that mobile telephone.

The CDR-31 can store a maximum of 100 entries
in each Contacts list, which can be added by sen­ding electronic business cards (vCards) from the
