Overview and Basic Information General Information
■Research has demonstrated that in certain cases medical devices can be affected by portable
telephones (DECT) that are switched on. This is why when within medical institutions you should be sure
to comply with the regulations of the respective institution when using portable telephones.
SWarning! Never
– open the charger or the mobile device (aside from the battery compartment lid)!
– touch the plug contacts with sharp, metal objects!
– carry the charger by the connecting cable!
■Only use a slightly damp or an anti-static cloth to clean your telephone. Never use a dry cloth. Never use
cleansing agents.
■Do not use your telephone in areas at risk of explosion.
■Do not use Comfort Pro CM 500 in damp rooms (e.g. bath).
■Do not hold the telephone in the hands-free mode next to your ear as the volume can be very high.
■Set up and keep mobile device and accessories outside the reach of children.
Note for Persons Wearing Hearing Aids
Persons wearing hearing aids should keep in mind that when using the mobile device at sufficient volume,
the resulting radio signal interference produces an unpleasant humming noise.
Overview and Basic Information
Authorisation is Required
Most of the features mentioned in this manual can only be used when you have the corresponding user
authorisation. Your system administrator configures authorisations when configuring the communications
system.
Contact the system administrator when you have questions on specific features or are not able to use a
feature satisfactorily.

General Information Overview and Basic Information
Further Documentation
Please use the other included documentation on parts of your communications system. This documentation
is on the Comfort Pro product CD.
DECT and GAP
A digital radio connection is established between the mobile unit and the base station (Radio Fixed Part, RFP)
in accordance with the DECT standard (DECT = Digital Enhanced Cordless Telecommunications). The digital
channel ensures the best voice quality without static or background noise. The Generic Access Profile (GAP)
is used for signalling between the communications system and the mobile unit.
The Generic Access Profile (GAP) and the DECT standard define procedures according to which digital
cordless telephones can establish connections. The GAP standard applies independent of manufacturer,
meaning that communications systems and mobile units of various manufacturers can be combined. The
basic functions (telephoning, accepting calls) are always available in these combinations; other functions
(e.g. displaying the call number on the display, displaying connection charges) which your Comfort Pro
communications system provides along with your mobile unit, may not be available with other manufacturers’
communications systems. Please consult the corresponding manufacturer’s user guide or contact your
system administrator.
Information on Transmission Quality
■Due to digital transmission within the frequency range used – even within range depending on the
structural environment – dead spots can result . In this case, transmission quality can be lessened by
increased and brief transmission gaps. A slight movement outside the dead spot will re-establish the
usual transmission quality. When a caller goes out of range, the connection is disconnected.
■In order to avoid radio-related interference with other electronic devices, we recommend as great a
distance as possible (minimum of 1 m) between the charger or mobile unit and other devices (e.g. radios,
loudspeakers, etc).
■As is the case with any cordless telephone, the mobile unit uses radio signals which do not guarantee a
connection under all circumstances. This is why you should never completely rely on cordless telephones
for essential communication (e.g. for medical emergencies).

Bluetooth interface can be used for transmitting audio data only with a headset.
Buetooth Qualified Design Identity
The Bluetooth QDID for your Comfort Pro CM 500/510 is: B014700.
Safety Precaution
Headsets (earphones and headphones) can produce tones which are very loud and high. When you are
exposed to such tones, this can lead to hearing damage. Before using a headset, please adjust the volume to
the lowest possible level. You can make these settings for cable-connected headsets in the >
Audio >
Volume > Headset (cable) menu (see page 104). Adjust the setting directly on the device with
Bluetooth headsets (please consult the device user guide). When telephoning with the headset, adjust the
volume – if necessary – slowly.
Comfort Pro CM 510 : Removing the Cover
The opening of the headset socket is closed with an undetachable cover. If a headset is not used, please be
sure to close the opening to be sure the device can be operated in accordance with its protection class.
Remove the cover by tugging it out of the housing on the upper edge.
Never tug it out on the lower edge!

Installation USB and External Charging Port
USB and External Charging Port
There is a mini USB port (2.0) on the lower right side of the mobile unit. It has two functions:
■As an interface for connecting to the PC e.g. to load data to/from the device. When the mobile unit is
connected to a PC it is charged simultaneously. The charging process is slower, however, than when the
mobile unit is charged in the charger.
■As a connection socket for a USB charger. This charging process is also slower than when charging in the
charger.
Be sure to use only a shielded USB cable.
Comfort Pro CM 510 – USB Port: Removing the Cover
The opening of the USB port is closed with an undetachable cover. If a USB cable is not used, please be sure
to close the opening to be sure the device can be operated in accordance with its protection class. Remove
the cover by tugging it out of the housing on the upper edge.
Never tug it out on the lower edge!
Setting Up and Connecting the Charger
“Comfort Pro CL 500”
As additional component you can purchase the Comfort Pro CL 500 charger
(material no. 40246042).
Comfort Pro CM 500: The mobile unit can be operated without changing the charger.
Comfort Pro CM 510: When operating the mobile unit, you
have to remove the two lateral guides in the charger. These
are easy to lift up on the inner edge using a fingernail or a
paper clip.

17
Power Supply / Power Supply Unit Installation
You can also remove the guides by pressing a suitable screwdriver in the longish
holes on the bottom of the charger.
Connect the power supply unit with the charger and place the connecting cable
through the cable guide. If necessary, change the connector of the power supply (see Power Supply / Power
Supply Unit on page 17).
Where to Set It Up
Your telephone is made for normal usage conditions. Today’s furniture is coated with a sheer myriad of
lacquers and plastics and treated with various lacquer care products. It is possible that some of these
materials contain components which can attack and deteriorate the plastic feet of the charging station. The
device feet altered by these foreign substances may leave undesirable marks on furniture surfaces.
For understandable reasons, the manufacturer cannot assume liability for these types of damage. This is why
you should use an anti-slip mat under your charging station – particularly with furniture that is new or has
been freshened up with lacquer care products.
NNote: Please make sure you do not set up the charging station in the space where doors or windows open: Damage Risk!
Power Supply / Power Supply Unit
The power supply unit is suitable for 100V to 240V alternating current (50-60 Hz). It comes with 4 inter-
changeable adapters so it can be used practically anywhere worldwide. As needed, put the connector on the
power supply used in your country. Mounting varies slightly as there are two variants of the power supply
connector:
Variant 1: Position the switch on the power supply at OPEN and slide the connector in place upwards and off.
Stick the desired new connector into the power supply and lock it by positioning the switch at LOCK.
Variant 2: Remove the connector if one is there by pressing OPEN. Then place the desired new connector
into the power supply slightly diagonally with the TOP designation showing upwards. Press it down until it
clicks into place.
When you wish to disconnect the charger from the power supply, pull the power supply unit plug out of the
mains socket. If there is a power outage, all memory data (programme and user data) are saved on the mobile
unit without alteration.
